Ergodic

[zoltran]

Please find attached the 'Ergodic' and the Ergodic Candlestick Oscillator from William Blau's book.

You would use the Ninja \File\Utilities\Import function to import the attached zip file.

[NinjaTrader_Josh]

Interesting work zoltran. Thank you for the contribution. I'll need to go pick up Mr. Blau's book and see how this Ergodic.

[whitmark]

Great work Zoltran . . . Blau's work has produced some really useful indicators and til now, have been noticably absent from Ninja. Thanks for your contribution.

[KBJ]

There are some instrucions in the souces that may make the Ergodic Oscillator more interesting...

Description from Investor RT
http://www.linnsoft.com/tour/techind/custom/ergodic.htm

ErgodocOscillator = TSI
ErgodocOscillator Signal Line = EMA(TSI)
ErgodocOscillator Oscillator = TSI - EMA(TSI)

By default, TSI is setup with a Short Term of 5 and a Long Term of 20 and EMA is setup with a period of 5.

Trading Ergodics with the Trend - Rules

1. Enter or hold position only when slope of ErgodocOscillator Signal line has the same direction as the trend
2. Stand aside when slope of ErgodocOscillator Signal Line is in the opposite direction of trend
3. Enter or exit position when ErgodocOscillator and its Signal Line cross

[KBJ]

Also, while figuring out the code, I added some comments to it, so I've attached an update for Ergodic.cs which should make it an easier read, and a beginner might have half a chance at understanding it.

Shameless advertisement:

With adequate commenting of all of the NinjaTrader indicators, there would be much less simplistic questions on the forums, and a lot less load on NinjaTrader staff answering them, and even more people would flock to NinjaTrader because of the user friendliness.

My services are available.

Oh, and I could even do slightly better than this example, if I were being paid for it.:)KBJ

[edgeliner]

KBJ.....

Can you upload your Ninjascript Strategy so that we can all comment on it and learn from it as well? I would personally like to implement it with my trading. Thanks!

[KBJ]

This one isn't for the Ergodic, but I posted a strategy for the FastStochastic which the Optimizer was able to get 73% success out of. It needs lots of testing on other time frames and such.

Here it is: http://www.ninjatrader-support.com/vb/showthread.php?t=3615

[saschja]

I've been searching all over the forum for a slingshot indicator, but couldn't find such an indicator for Ninjatrader.

Anyone ?

Thanks in advance.

Adapted from Blau's Momentum/Direction/Divergence by zoltran (Wes S.)


The following is the Ergodic Candlestick Oscillator.
The ECO is a Momentum Oscillator that is not affected by opening gaps. See William Blau's Momentum/Direction/Divergence book.

It is used in a very similar manner to other Momentum indicators such as CCI, MACD or the Ergodic.

The 'Candlestick' part comes from the formula's use of just the open-close vs high-low.
It's primary advantage is that is not affected by Gap openings. It totally ignores them giving a better view of current momentum.

You can see this in the attached screen shots.
The trend was flat-to-down on 11/29. There was a gap open on 11/30 that ended up also being flat to down and eventually sold off.
The other indicators were all pegged high overbought/in the green due to the gap. The ECO pretty much ignored it. Same for 12/5.

There are some interesting strategies for using this indicator.
As they are on another charting programs web site.. I'll leave it to the reader to do a google for it. Try a search for ergodic candlestick histogram

/----------------------------------------
Trading Ergodics with the Trend - Rules

1. Enter or hold position only when slope of ECO Signal line has the same direction as the trend
2. Stand aside when slope of ECO Signal Line is in the opposite direction of trend
3. Enter or exit position when ECO and its Signal Line cross
4. Take note when the ECO is 'inside' it's signal line. This indicates failing momentum
This is what the magenta "Fading" dot signifies

// Formula for Candlestick oscilator from Blaus book is
// EMA(EMA(close-open),r),s)
// CSI(r,s)= 100 x --------------------------
// EMA(EMA(high-low),r),s)
//
// The 'Ergodic' version adds signal line, wich is a 5 bar ema of the CSI

v1-4 -Fixed Plot Overflow- again Dec 18

[KBJ]

(Cleaned up comments so KBJ doesn't scold me ;-) )

You've done well.

[deanldavis475]

1st a question. What determins if a bar is red or green and what causes the change. 2nd can you easlily tell me how to insert a line at plus 15 and at minus 15?? I love the indicator so far (2 days). Thanks

[zoltran]

Green Bar = Rising ECO line .. ie the ECO line is greater than the prior bar
Red Bar = Falling ECO line
Same for the Ergodic Indicator

You can adjust the line levels when you add the indicator to the chart. Look for the 'Lines' section on the right of the Add Indicator dialogue .. just above where you change the color/size of the plots.

If you want an additional line, you can use the standard NT indicator called "Constant Lines" . It is used to place any arbirary line on chart/panel.
Apply it to the same 'panel' as your ECO, and adjust the line levels/color/formats as you wish.

[deanldavis475]

Thank you so much. I forget about the constant line indicator.

[deanldavis475]

Any idea why I can get ECO to run on a tic chart of any number of tics, a 2 min chart but not a 1 min or a 3 min or any other min chart ??? Strange !!! The panel is just blank

[zoltran]

Sorry,
It works fine here on all 3 types of charts. Have not had a problem.

Are there any entries in the NT log? For example Index out of bounds?

[deanldavis475]

I do findan error that reads

Error on plotting indicator. Please check the "Plot" Method. Overflow error.

[zoltran]

Yes, ... I'm seeing that now too...
Weird that I didn't before. I'll try and find a solution

[zoltran]

It should be fixed now Dean.

Updated the original post below with the 1.1 version.

I didn't skip enough 'look back' bars so the code would some times have an overflow error. Depended on what the price data was.. which is why I think I didn't see this before

[deanldavis475]

Thanks I will try this one out and let you know my results.

Thanks again

Dean

[deanldavis475]

Sorry but now I can consistantly get a 1 min but not any other time frame no 3 5 min etc.
Same error message as before

Dean

[deanldavis475]

When using the new version, There are no pink dots. Did you intend that???
Dean

[zoltran]

Fixed. Thanks for catching that. I had removed them temporarily when trying to find the plot error. See ver 1.2 in original post

[deanldavis475]

OK the dots are back and here is what I discover about the time problem. If on a minuite chart I bring in more that 4 days history on a 2 min chart the indicator will not form if I reduce the days to 4 the indicator will form. For a 3 min chart the Max days is 2. Also, today is Wednesday and the property for exclude weekends appears to change the results.

Hope this is helpful to you and sorry I am not able to really assist in fixing the problem rather than just nagging about it.

Thanks again.
Dean Davis

[zoltran]

Hmmm

The logic/Math in the ECO is pretty simple.. but a friend has told me he gets this too..

Nevermind .. I can re-create the problem here now using the info you provided.
Don't know what's wrong yet .. but at least I can test it.


What are your begin/end times for the charts?
Also what symbols and who is the data provider?
And do you get an error in the log?

[deanldavis475]

I am still getting the same error message Please check the Plot method Overflow Error.

The range on my charts is
if weekends excluded 1 min 5 days back OK, 6 days Not OK
if weekends included same as above
2 min no settings would get the indicator to show
3 min with weekend excluded 4 days back ok 5 days back not ok
3 min with weekend not excluded 2 days back OK 3 days back not ok

begin and end time for charts is 12:AM and 12:AM

[zoltran]

Ok .. Try again please. Version 1.4

Found the root cause.
Problem was an error 'skipping' the 1st few bars that left invalid data behind,causing an overflow result to happen.

So far, I can't make it fail with these last changes

Pls note, that this indicator needs about 100 bars or so to 'warm up'.
Results are inaccurate before this time.

[deanldavis475]

Thank you for keeping on keeping on. This one apprears to work as expected on all tim frames.

Thanks

Dean

[crossover]

Also, while figuring out the code, I added some comments to it, so I've attached an update for Ergodic.cs which should make it an easier read, and a beginner might have half a chance at understanding it.

KBJ

I suppose that the ergodic is calculated at the close of the bar
Is there a way to calculate the ergodic with as input a macd or cci?

[NinjaTrader_Josh]

It is doable, but you would need to go into the code and change it to use your MACD or CCI as the input DataSeries instead of Close prices.

[crossover]

I have the script in front of me but i know nothing about programming the script
Editing the input dataseries..........yes but i dont have any idea how to do and what tu use as dataseries..................

the idea of using a cci as input is to eliminate the " noise" of the cci


The Ergodic formula is a ratio of two double averages. The numerator is an average of an average of the Net. The denominator is an average of an average of the Absolute value of the Net. The Net is the difference between a bar's close and the prior bar's close.
Ergodic = (Average (Average (Net, parameter 1), parameter 2) / (Average (Average (Abs(Net), parameter 1), parameter 2)

[NinjaTrader_Josh]

It may be best to contact the original author of the custom indicator since due to bandwidth issues we cannot provide direct custom coding.

You can also try contacting one of our NinjaScript Consultants here: http://www.ninjatrader.com/webnew/partners_onlinetrading_NinjaScript.htm

[zoltran]

I've made a new version of the ECO that displays the rising/falling status a bit differently.

- Histogram - Green over 0, Red below 0
- ECO Line - Green when Rising, Red when falling

Same formula, just a different display.

Colours in the screen shot are gaudy on purpose, just to show the lines.
ECO 2 on the bottom

[zoltran]

Updated ECO2 to correct some formating problems.
Sure wish NT had an easy way to draw a rising/falling line without using two extra plots.

Please re-download from the original post (#32 below)

[Druid]

Zoltran,

Thank you for keeping the ECO indicator updated.

Much appreciated!

[zoltran]

I've been playing with an idea about using the ECO State as a price bar.
I don't like a lot of indicators on my chart, and this is an attempt at mapping the important info from the ECO indicator onto the price panel.

That is ...

Green = Strong Long ECO, Above Zero, Above it's signal line, and over a minimum 'chop' threshold
FadedGreen = Weakening Long ECO, Above Zero, BELOW it's signal line, and over a minimum 'chop' threshold
Red = Strong Short ECO, Below Zero, Below it's signal line and a minimum 'chop' threshold
FadedGreen = Strong Short ECO, Below Zero, ABOVE it's signal line and a minimum 'chop' threshold
Yellow = Chop ... ECO between the chop threshold (default =/-8 .. can be tuned)


Also plot dots to show ECO hooks or 'ZLR' on the price panel.
Not sure how useful this will be .. but it was an interesting exercise.

[crossover]

I have been experimenting with the ergodic indicator and it is working fine

I use the 24,6,14 and the cross for buy and sell is good indicated.

I did a lot of work to have it in a startegy for NT but i wont succeed...


any idea how to do that?

[meyer99]

Nwbie Q here:
After I download the files what should I do next to be able to use the ECO?
Save to NT folder, import, etc?

[meyer99]

Zoltran,
Have you/can you do the high/low activator?


Here is the Metastock-Version of GANN - HiLo

HLd:=If(CLOSE>Ref(Mov(H,3,S),-1),
{then}1,
{else}If(CLOSE<Ref(Mov(L,3,S),-1),
{then}-1,
{else}0));
HLv:=ValueWhen(1,HLd<>0,HLd);
HiLo:=If(HLv=-1,
{then}Mov(H,3,S),
{else}Mov(L,3,S));
HiLo;

It's the three-period moving average of the highs or lows plotted one day forward (see page 55 of the February 1998 S&C). If the market is in an uptrend and today is day 4, the hi-lo activator for day 4's trading is the low from days 1, 2 and 3 added together and divided by three. This value is the hi-lo activator for all of day 4. It does not change until the close of day 4. Then, for day 5, the hi-lo activator is the low from days 2, 3 and 4, added together and divided by three. The same concept applies for calculating the highs.

[eDanny]

Played with Ergodic a little bit and changed signal line colors depending if rising or falling, above or below the zero line.

[eDanny]

After reading about the use of the ECO2 indicator I thought I'd try it out. I made some modifications to enhance quick viewing of the indicator status. If the ECO line looks flattish but you want to know if it is really angling up or down, I have a box showing the difference between the current value and the last value. Also if the signal line is above the zero line and the ECO line is above the signal line you will see "LONG" and the opposite will show "SHORT". If the ECO line then falls below the signal line but is still above the zero line you will see "FADING" as well still see the dots plot on the signal line. As always the alerts can be on, off, left or right. Enjoy the eye candy.

[zoltran]

Thanks for the update

Hi
Is Eco2 a variation of Ergodic or are they 2 different indicators? I haven't checked either yet.

Javier

[eDanny]

Yes they are different indicators but look similar. One difference I see is ECO2 doesn't react wildly to gaps. I have made ECO more user friendly today to actually give potential trades signals, to be filtered by all your other indicators and signals of course. A signal is forming when a transparent triangle appears at the zero line. Also a sound alert, if turned on will give you a heads up. If the signal is still valid the the close of the bar, the triangle will change to a color and another sound will alert you. If both the ECO line and signal line are in the right direction the triangle color will be dark and if one line is angling in the opposite direction the triangle will be a light color. This small filter may alert you to change in direction. The picture will show a signal forming and also an example of the lighter triangle and the condition that caused it. To me, this is much more useful than the fun text signs (which can still be used). Good trading!

[mahlonhersh]

Danny,

I like the work that you've been doing with the Ergodic and ECO2 indicators.

What are the parameters that you are checking to generate buy and sell signals with the ECO2?

Thanks,

Mahlon

[eDanny]

A short signal for example is generated when the main ECO line is below zero and the signal line crosses below zero. If the ECO line goes back above the signal line but then crosses below the signal line another short signal is made. I don't know if that is the correct way but it seems to be the most effective. I think I read that a short is when the signal line crosses the main line but if that were to happen above the zero line it is an indication of fading, or a possible reversal but I wouldn't think it is strong enough to signal a short. My opinion only which can change over time.

[mahlonhersh]

Danny,

Thanks for the explanation.

Would it be possible to have the ECO2 or Ergodic histogram show different colors when rising or falling, for example green when rising and red for falling? Like the Bill Williams Awesome Oscillator does. It appears that the ECO2 has a selection in the setup for this, but it didn't seem to work for me. I tried using the main rising and falling line and plotting it as a bar, but that wasn't real accurate either. Apparently the main line doesn't always change colors when it goes up and down.

I do really like what you have done with the alert dots on the Ergodic. (the start of the fading) I find this to be a pretty strong reversal alert, especially when used along with other indicators.

Thanks for your consideration,

Mahlon

[eDanny]

Making the histogram change colors would be a major re-write of the code but I may tackle it sometime. I also looked at the main line color changes but don't see why it doesn't look right sometimes. The fading dots were part of the original code by Zoltran.

[mahlonhersh]

Thanks. I am not a programmer, so I would be lost for sure! Maybe Zoltran has some input on this.

[Elmi]

zoltran is it possible to have available just the signal to plot it on price or on another panel as well ?
Thanks for sharing with all of us.

Thanks for the coding it's awesome!


Did anyone figure out a way to automate as part of a hands-free-system?

[Javier]

Hi eDanny:
I use your ECO2new in my charts and find it very useful, but often, not all the time, the ECO line does not change color from green to violet or vice versa as prices change from raising to falling or the other way around.

This odd behavior is corrected when pressing refresh (F5 key). I have other indicators on the same charts that plot correctly while that is happening..

I wonder if someone else is experiencing the same behavior or if you know a way to correct it.

Thank you for this indicator it is very good aid.

Javier

[eDanny]

I can't take the credit for these indicators. I just spruced the ECO2 up a bit. I have the same ECO main line behavior but a look at the code shows it should work right.

[Chartsky]

Thanks for all your work Zoltran . . . I've really missed the Ergodic coming to Ninja from another charting program. Glad to now have it again.

[vast524]

Thankyou to all for the work on this indicator.
I am wondering how this indicator works. I looked in the indicator editor and saw that it uses: open, close, high and low.
Is this based on the regular trading hours or only so many candles before?
If it was the first way which I believe it isn't I guess it would need session times to function correctly.
Thanks once again
Regards
A

[zoltran]

OHLC refers to the current bar.
It doesn't use or know about the session start times.

In fact, the ECO indicator only knows about the current prior bar.. which is why it's not affected so much by gaps.

Mr Blaus book explains the background behind them

[vast524]

Thank you for your explanation Zoltran.
I am wondering if you are able to help with a little problem I have.
I have x2 machines that are running Ninja. There are times when the graph lines drawn by Eco are different on both machines. Both are running Zenfire, with the same version of Ninja and the same version of Eco. They are set up the same way and are running 1 min charts. I am using them on the ES and TF charts.
Any help would be appreciated to explain why there are differences please.
Regards

[eDanny]

This will probably be the last enhancement I will make to the ECO2 indicator. Just made a quick change to allow switching between the standard histogram, one color above zeroline and another below, and a histogram with colored bars for rising or falling main line.

OK, I had exported with the new name ECO2new and posted that file. I just applied my ECO2new to a chart and it works. Thinking the export may be corrupt I deleted the indicator and imported fresh and it still plots. Either you are doing something wrong or something happened to the file during the upload to the forums. Try deleting the indicator and re-importing it.

[eDanny]

There have been requests for the histogram to change color in the Ergodic indicator if the Main line rises or falls. After getting a PM about it I made the change so it works like the ECO2 histogram now, user selectable. This will overwrite the last update since the indicator is still called ErgodicNew.

Hello zoltran and eDanny.

First, an absolute THANK YOU for the hard work on this indicator. If you read my blog, you already know it has become an integral part of my discretionary trading. I talk about it often and have high praise for it.

I have a couple of questions I've been unable to reliably answer for myself so far. I will upload a pic of one of the charts I used for today's blog post so you can see my ECO2 settings on my chart (you can ignore the rest).

edit: was too big for forum, arrggghh, so click here (http://i43.tinypic.com/10n9wnn.png) for the picture

1) Sometimes the main line can be falling, yet still be green. What is the significance of this? Does it mean that the EMA is falling but the Close was higher than the previous bar?

2) Sometimes I swear the ECO2 repaints the last bar (for instance, it was purple but is now green, 1 bar later). I have yet to put my finger on this, if I am just noticing the intrabar updates (I do have calculateonbarclose = false) and not paying enough attention, or if it truly is repainting the last bar. Can you confirm if it repaints, or not?

Thank you.

Mike

[zoltran]

Hi Mike

I think I see the problem .... And I bet it does repaint.

As you may know, you have to use two plots to display a color change, one for each color. There's a problem in the logic that changes color ...
I remember doing this because I kept getting blank spots in the line when it changed direction.

I think that Values[3][1] = eco[1]; line will repaint the bar...

My bad

I'm heading out for a short vacation .. Don't think I'll be able to fix this until later next week


if (eco[0]>eco[1]) // Plot green bars for rising eco, red for falling
{
if (eco[1]<eco[2]) Values[3][1] = eco[1]; // connect prior secgment Paint falling eco if (CurrentBar > Slow+Fast+SignalLen)
Values[3].Set(eco[0]); // Paint Rising ECO2 Line
}
else
{
if (eco[1]> eco[2]) Values[4][1]= eco[1]; // connect prior secgment Paint rising eco
Values[4].Set(eco[0]); // Paint falling eco
}

[zoltran]

Mike .. I'm not sure I can fix this...
It's the same technique that's used by the 'samplemulticolorplot' example.

But .. you can change the 'histogram-type' variable to true and I think the bar color will acurately reflect the direction.

[ctrlbrk]

Hi zoltran,

Thank you for the quick attention and response. I will try setting to true and see what that does, I've only tried false up to now.

I hope you enjoy your vacation!!

Mike

[eDanny]

Mike, I'm glad you like the indicator but Zoltran is the guy to thank for it. As far as the line color glitch it is something I have seen in oscillators where you stitch two color plots together to get a color change on direction change. It doesn't always work and I don't know why. You will just have to watch the line more closely I guess, unless someone else comes up with a cure.

[mrlogik]

Danny is right about the line stitching, this is why.

When you switch colors on a line, it has to connect two line plots.

So, if it changes colors 2 times on 3 consecutive bars, the color will be the same through all 3 bars because it is overwritten by the "connecting line."

If you change the plot style to dots or something else, this shouldn't happen.

NT knows about this limitation (I posted info about it here (http://www.ninjatrader-support2.com/vb/showthread.php?t=8728&highlight=plot+color)), even though its a little different coding method.

hope this is informative

[simjs]

Hi eDanny,

Prof Logic Charts.

Thanks.

[zoltran]

Thanks Mr Logik for the info on color plots .. I thought I was going mad..
And to eDanny for some great improvements to the eco.

Since the standard two color NT process will end up repainting ... I took it out.

Now, the ECO line will show 'Yellow' any time it turns... and it won't repaint it.

I took eDanny's version and added this change to it.

I also broke out the "Parameters" from the 'Display Parameters'... and this can be seen in the picture below.

This has two important things to remember ...

1) Now .. the parms that affect calculation, and strategies are simple to specify .. fast, slow, and signal ... thats it.

2) Since this parm changes the way it's called in a Strategy, I saved it as ECO2New2...

Enjoy ..

Awesome thank you. I will incorporate this into my templates, and then later into my indicators and strategies after I see how the changes impact them. But the biggest thing I wanted was the visualization aspect of the re-paint to be "known" or as you've done -- "corrected" -- even better!

Also I like your VMABands, I discovered something similar and released it as VMA Zones, yours is much more advanced and looks nice :)

Hi,

Actually I had tried the Ergodic indicator (latest version) and find it different than the prof logic ergodic indicator. So I am looking for some help to change the ergodic indicator to match with prof logic ergodic indicator.

The charts I post are the prof logic chart with ergodic indicator.

Thanks.

[NinjaTrader_Bertrand]

You would then need to look for the TSI (True Strength Index) as the basis of it...

Hi All,

I just noticed that the ECO2New Indicator has an additional bar of lag over the previous ECO2 Indicator. This is on a 4 tick Range chart.

could some one help me to paint my frama_4 up green down red sideways yellow its one of my main indicators and colors would make it much simpler to read here are the settings 2-3-15-7-close-34
frama-k band is yellow and the other 2 bands are netural if someone colud figure this out for me i would appericiate it thanks sam

Hi sharky2372, the technique needed is discussed in the reference sample here - http://www.ninjatrader-support2.com/vb/showthread.php?t=3227

here is a better pic of what i mean i would like up one color and down one color and sideways one color like the double ma you guys have posted... sam

[velocity]

So simjs,

I too am still a little confused by your post. Where is the code for your "prof logic ergodic indicator" in Multichart program so that someone can migrate it over.

[NinjaTrader_Bertrand]

Hi sharky2372, I followed what you had in mind, unfortunately we don't provide custom coding services - for this you would need to work with a NinjaScript consultant - http://www.ninjatrader.com/webnew/partners_onlinetrading_NinjaScript.htm

[shark bite]

yes im aware that you dont provide custom work i just thought that anyone could try to do it and it would benifit everyone.... thanks anyway i will look elswhere...sam

[zoltran]

Right Bertrand

The 'Ergodic' is just based on the built-in Ninja TSI indicator.
The Ergodic applies smoothing to the TSI and plots the histogram and Signal line.

ECO is Blau's 'Ergodic Candlestick Oscillator ' and is different.
It's looking at the difference between the High/Low and Open/Close .. much like a Candlestick chart does. Hence the name. And it only looks at the current bar. Period.
That's why it isn't affected by Gaps.. No Rocket Science ;-)

The bulk of the coding in both indicators is just to handle the different colors and plots.

[zoltran]

Hi All,

I just noticed that the ECO2New Indicator has an additional bar of lag over the previous ECO2 Indicator. This is on a 4 tick Range chart.

RJay


Rjay ... There should be no differences in 'lag'.. as it was just a color change.

Can you post a screenshot with both the Old and new eco on the same chart, so I can see what you're looking?

Hi Raj
You have different parameters on each.
3,5,14 for the old one, and 7,4,21 for the new...

So it will look different.....

[zoltran]

William Blau created the ECO .. I just coded it for Ninja, using the formula in Mr. Blau's book. There's not a lot of info on the net about the ECO, so I thought I'd add a bit more here on the 3 ECO parms.

The 3 parms are slow, fast, and signal

The 'slow' parm is the cycle time, and is similar to a Moving Average length ..
- It mainly affects how quickly the ECO will move above and below the Zero line.
- Try different lengths here ... Longer.. such as 30, or 50, or even 100 do a good job of showing the longer term trend.

The 'fast' parm controls how smooth the the ECO line looks. It could have been called 'smoothing'. Longer values will smooth out the jagged edges. You'll notice it doesn't introduce much lag...

The 'Signal' parm controls how tightly the signal line hugs the ECO.

Take a look at the screenshots that Raj posted below to see some differences. I'll post some of my own later this week

Check "format data series" for how many historical days back you are showing on the chart. Try increasing it.

Also make sure calculate on bar close = true.

hey rjay yes your right my panel 3 is the eco my panel 2 is mikes new macd but both of them i made lines netural in color just for my trading style you can do this to just down load the indicators and show all the indicator colors or only what you need, for my style of trading i dont need the lines and historgrams so i just show what i need so i dont have too much to look at when i trade...sam

OK, I see it now.

[suchen]

has anyone been able to incorporate the JMA moving average into the DoubleMA as an option, if we subscribe to Jurik MAs?

[nkhoi]

yes you just need to add the JMA.

[suchen]

I am not a programmer...so I don't know how i would go about adding this option to the DoubleMA indicator? I got the indicator from BigMike who added multiple different MAs within the DoubleMA and I love this option he provided...

[ctrlbrk]

Edit the MAV.cs indicator, there are three sections if memory serves you need to add the new Jurik JMA. Under #variables, under onbarupdate there is a case/switch, and under parameters.

It should be fairly obvious how to do so from there. Remember Jurik has more than just Input and Period, there is another component something like Phase, so you'll need to provide that as a static value in the syntax because DoubleMA isn't built to have that as an extra variable without more code change.

Mike

[shark bite]

well im revisiting the eco indicator from big mikes blog worked well today for 2'200 dollars profit,btw thanks mike for recomending the 4 range works well been trading 144 tick and 89 tick for so long just got use to it..sam

[shark bite]

hey traderandreas the sam trend bars are mod ha2 and the eco you can get off of big mikes blog
http://ctrlbrk.blogspot.com (http://ctrlbrk.blogspot.com/)

[traderandreas]

Thanks Sharky for the reply and post.
cheers

[shark bite]

mike why dont you try using my sam mod ha2 bars instead of the trend bars you use you can play around with them if on the default settings you get the yellow bars for some chop but if you set it on 1 and 1 or 2 and 2 and so on then you just get 2 colors for trend just a suggestion but i dont really care for the super trend bars and here are the eco bars also if you want to play with them i could not get them to fit my style but maybe you can...sam

[shark bite]

hi everyone just wanted to adress something ive been running into for some time now i noticed everyone is still looking for the holy grail indicator even guys ive traded with for years,there are so many addons and 3rd party indicators for sale or lease out there and trust me ive tried a bunch of them to many to be frank lol but ive came to the truth that the holy grail is me and you. if you will put hundreds of chart hrs in just looking at charts in real time and also historical data and think about what makes me see this chart so im comfortable in entering a trade and when do i feel like the trade is done then you will get so that trading is 2nd nature for you.just find a indicator or 2 that helps you see the market dont always try to see the market from someones elses eyes or mind because we all think differently.find what works for you clear your head relax and just feel the market and trade,well that all for today i hope that my post today will help even if it is just one person then i did my job...sam

[toddaclark]

Sam,

I've been following your comments and charts on Mike's blog. I'd like to ask some questions about your trading style.. I've appreciated your posts.

Do you trade ZN exclusively?
Can you share what you look for to get into a trade?

TC

[ctrlbrk]

This is why Ninja desperately needs an off-topic section in the forum.

I am sure zoltran doesn't want all this blog talk taking up space on his thread, wanting to keep it relevant to Ergodic only.

I want to read your thoughts and discuss etc, but perhaps a different thread would be better.

I would suggest you use this thread for now, it is meant for this type of discussion:
http://www.ninjatrader-support2.com/vb/showthread.php?t=15572

Mike

[zoltran]

Oh I don't mind ;-)

[WhoKnows]

Something I could not yet find.

I want to use the difference between the main and signal line.
The rough idea is to e.g. exit when main and signal start moving towards each other.

Apparently something like the following does not work.
if ((ECO2New2(1,2,3).Main[0]) - (ECO2New2(1,2,3).Signal[0])) < (ECO2New2(1,2,3).Main[1]) - (ECO2New2(1,2,3).Signal[1]))

Anybody an idea how to approach this?

Edit: corrected the type spotted by fast Velocity.

[velocity]

WhoKnows??? (pun intended)

but, do you have a typo? one too many comas???

ECO2New2(1,2,,3) should be ECO2New2(1,2,3) ?

[WhoKnows]

That was fast .. Velocity. Well spotted, but it isn't the comma. Made a mistake copying.

NT complains about:
; expected
Statement expected
Invalid expression term '<'

[ctrlbrk]

WhoKnows,

I would simplify things first. If you only need the current bar value, then do something like

double diff = Math.Abs(ECO2New2(1, 2, 3).Main[0] - ECO2New2(1, 2, 3).Signal[0]);

then do your logic from there. Not sure if math.abs is what you need or not, depends if you always want a consistent positive number, or if you want a negative number sometimes. I would approach with math.abs and just determine long or short by whether above or below the signal line.

Mike

[WhoKnows]

Thanks, two answers in one. I was looking how to define the absolute difference. Ok, I'll dumb the expressions down then.
As I need to diff of the past bar to, probably I have to go with a new dataserie for diff.

As I never dataseries stuff before a question.
- if you define a new diff dataseries and in the indicator code you loose your work is the indicator gets updated. If there any issue with introducing the diff dataseries and the logic in the strategy itself?

[ctrlbrk]

If you need past bar values:

#variables
private DataSeries diff;

#init

diff = new DataSeries(this);

#onbarupdate

diff.Set(Math.Abs(blah - blah));

Like so. You don't "lose" anything, I am not sure I know what you mean by this.

Mike

[WhoKnows]

Thanks Mike,
I meant that with rapidly developing indicators, with every new version you have to port your own adaptation to that new version.

[ctrlbrk]

Gotcha.

Just put your DataSeries and diff in the Strategy, not the indicator, like you said.

If the indicator itself isn't going to plot these values (diff), then no need for it to be in there.

Mike

[starrynight]

What exactly does the ECO2 signify ? Like I know MACD is a MA of a MA and smoothed but what does the ECO2 track , price , MA's , price closing near its highs or lows ?

[zoltran]

Hi starry...
That's been covered a few times in the thread... Take a look at the 1st post as well as a couple others of mine in this tread as well.

Basically it's a smoothed difference of the relationships between High/Low and Open/Close... much like a candlestick hence the name.

Originally developed by William Blau

[toddaclark]

Zoltran,

Thanks for your work on this indicator! I've only been studying it for a short amount of time, but I really like it.

Here is a link to a picture of how I'm using ECO2.
http://screencast.com/t/ty3cr3HndL

Would it be possible for you to make the following improvements to ECO indicator:

1. Paintbar - paint bars red when the eco line is red, blue when blue, yellow when yellow (I've chose yellow as the color of the main which only shows when there is no rising or falling bias).

2. Arrow - Blue arrows when it moves from yellow to blue...red arrow when it moves from yellow to blue?

3. Audio alert - "possible long signal" - when the eco line turns blue...."possible short signal" when the eco line turns red.

I don't know much about programming. I don't know if that is 5 minutes of work for you or 5 hours...

You might even have better ideas... I've only been looking at this indicator for a short amount of time.

Thanks,
TC

[toddaclark]

Zoltran,

Did you get the last reply? I didn't get any response.

The paintbars are more important to me than the other things but they would all "be nice". I can compensate you for this work, I just don't have the skills to do it myself.

TC

[zoltran]

Hi todda
There already is a version of the ECO that paints the bars.
Read down near begining of this forum... Like at http://www.ninjatrader-support2.com/vb/showpost.php?p=28435&postcount=35

See if this is what you want ..

[toddaclark]

Hi Zoltran,

I've seen the ECO bars...those do not help me.

What I want is:
Candlestick Paint Bars that will paint the bars to match the color of the ECO Line. I'm currently using blue for rising, red for falling and yellow for main when neither rising or falling is dominant.

The arrows and alerts are not important at this point.

Is that something that you can help with? I'm currently using the ECO2New indicator that Big Mike modified from your original design.

Please let me know.
Thanks,
Todd

IMHO, I'd recommend looking over the BigMikesTrading Forum (free), much info available, then if you find value there, by all means the nominal ($50 I think) fee to have access to Elite areas is a bargain.
