Hello,

You auto trend line is GREAT! I love it.

Have a question for you. How hard would it be
to devise a indicator that works the same type of
way but works with divergence?

Ie - plots the divergence between price action
and say macd or stoch or both :-)

Thanks,

Colin

Thanks Ray for the auto trendline indicator.

When I tried to install it is trying to overwrite the default "swing"indicator, is this expected? Does it change swing indicator in anyway?

What does the "strength" field indicate? Does it indicate number of swing pivots needed for drawing the trendline?

Did you test whats the optimum strength field for ES 3 min chart. Appreciate your time on this.

Thanks
RK

[NinjaTrader_Josh]

The reason it is trying to overwrite the Swing indicator is because the way the export NinjaScript is designed is to allow the export file to work on its own. You can safely overwrite your Swing indicator as it is the same file. There will be no changes done.

[NinjaTrader_Ray]

Strength represents the number of bars left and right of a pivot required to form a pivot. I have not done any optimization to determine best values on any time frame.

[RK_trader]

Thanks Josh. I appreciate it.

Do you know what the "strength" field indicates? Does it indicate number of swing pivots needed for drawing the trendline?

Did you test whats the optimum strength field for ES 3 min chart. Appreciate your time on this.

Hi

Any active users of this auto trendline indicator, did you experiment with what "strength" property value you are getting good results? I tried 5 and not sure if it is good.

Also when does it give the signal. Does it wait for atleast one bar to close below the current trendline?

Josh thanks for good indicator. I am not a Ninja programming expert, trying to learn the indicator programming. Is it possible you can modify the indicator to include a property field "the number of bars to close below trendline to give signal"

Also I would like to request if you are considering enhancements to make the trendline a little below the swing lows with a "displacement". For example in an uptrend the trendline is joining the swing low pivots. I am finding that if the trendline is a bit conservative and like a few ticks below the swing lows, it is holding well. For example, if the swing lows in ES uptrend are like 1531.50, 1535.50, 1540.50, then a line joining 1531.25 ,1535.25,1540.25 with 0.25 displacement to downside is holding really well and when it breaks, it gives a very strong signal and doesn't give false signals. May be this can be enhanced by adding a "displacement field" to properties.

I appreciate your time and any active users opinion on this.

Thanks

[NinjaTrader_Josh]

Unfortunately I cannot provide assistance on this indicator RK_trader. It wasn't me who programmed this one and so I do not know what the parameters do or mean.

[RK_trader]

Thanks Josh for the quick reply. No problem.

I would appreciate opinions/comments on people who are actively using this indicator. Any volunteers who can modify the code to get the enhancements/options.

Thanks
RK

[NinjaTrader_Ray]

The indicator waits for the first value lower or higher than a uptrend or downtrend line. If the indicator's "Calculate on bar close" is set to true, it will wait for a close of the bar otherwise just the first tick.

Unfortunately I will not be ammending the code to provide extra user defineable parameters however, anyone can take this open source code and modify it as they wish.

[RK_trader]

Thanks Ray. I am still in learning phase of Ninja programming.

I see "calculateonbarclose" on line 42 in Initialize() and it is set to true

And the other place I see it is on line 298 which says as below:

indicator.CalculateOnBarClose = CalculateOnBarClose;

Can you please clarify as to in which line, I need to change the value to true, so that it waits for a a bar to close below the trendline to give the alert.

Appreciate your time on this.

Thanks
RK

[NinjaTrader_Ray]

Line 42 should be set to 'true'.

[RK_trader]

Hi Ray,

In line 42, it is already set to true.

Thanks
RK

[APat1]

If it is set tof alse the calcs are on incoming tick basis.
Probably can change it in the indicator prop window.
Pat

[RK_trader]

Hi Apat1,

It is set to true in the code and also in the properties window by default. But I see it gives signal even before a bar closes below the trend line. Not sure what to change to fix it, so that it gives signal only when a bar "closes" below trendline.

Thanks
RK

[Mike_32]

Does anyone understand the methodology of using this indicator?
When it gives a long trendline are you supposed to go long?
Or wait until it goes long and gives the arrow of breaking the trend then go short?
What is the arrow breaking the trendline supposed to signify exit the line trend or go other direction?
Thanks

[NinjaTrader_Ray]

There is no trading methodology on this indicator. Its purely a visual that draws trendlines and alerts you to a break. Interpret as you see fit.

[superarrow]

Hi Ray,
Firstly, thanks to the best indicator I ever used. It makes my trading so much easier.

Now, I need to visually analyze the price for the whole day, not just during an active trendline drawn object. I tried to comment out all the "RemoveObject..." to try and keep all the arrows for the previous trendline breaks. However, this does not seem to work.

Would you be able to advice/guide me to make this feature possible? Appreciate your assistance.

Happy Thanksgiving to you and the entire NT team. You guys do a great job.

Cheers,
SA

[NinjaTrader_Ray]

You are welcome...Not looking at the code, I suspect in the DrawArrow() call, the same tag parameter is used for each break, try changing this to be unique such as:

DrawArrow(CurrentBar.ToString()...)

[superarrow]

Ray,
Thank you. Works!

SA

[pgabriel]

Is it possible to modify this indicator to leave a history of the prior trend lines on the chart when a new one is plotted...?

[NinjaTrader_Bertrand]

Hi pgabriel, you could apply the same concept as discussed for the plotting the past break points (unique tag ID's) to the DrawRay() statements by adding + CurrentBar to them...this would then create a new draw object each time leaving the history of objects unmodified.

[goldfly]

Here
http://www.ninjatrader-support2.com/vb/showthread.php?t=6648

Get "TrendlinesAll.zip (http://www.ninjatrader-support2.com/vb/attachment.php?attachmentid=2217&d=1208053993)"


Edit: I'm not sure how I did that, but you can just click TrendlinesAll in this message.......

[pgabriel]

Thanks... that was quick...but as the lines are all rays it really clutters up the chart...can you limit the history to just the current day...?

[diage4]

Some trendline softwares have delete old trendlines functions.

I noticed that there are so many great trendlines for Metatrader, but unfortunately this is very different story for Ninjatrader.

Is it because Ninjatrader is difficult to program trendlines? Or is it because people who are not interested in developing indicators for Ninjatrader?

[dannyss35]

well I downloaded the file and saved it on my desktop. I have to copy and paste however I do not remember how...anyone can help me?

[NinjaTrader_Bertrand]

Welcome to our support forums dannyss35 - just go to File > Utilities > Import NinjaScript and point to the downloaded zip file then.

[timokrates]

Hi,

first, thanks for this tool.

One question: Could it be modified to also draw the contrary trendline to create a channel?

[NinjaTrader_Bertrand]

Hi timokrates, this would be possible - you can review the sourcecode of this study and work the needed changes in. If you need the modification professionally programmed, please consider contacting those consultants - http://www.ninjatrader.com/webnew/partners_onlinetrading_NinjaScript.htm

[jaybird151]

is there anyway that you can make this draw the up trendline and down trend line at the same time instead of it just plotting 1 or the other


thanks

[NinjaTrader_Bertrand]

Hi jaybird151, this should be possible, but unfortunately we don't offer custom code modifications. You could contact a NinjaScript consultant for this project - http://www.ninjatrader.com/webnew/partners_onlinetrading_NinjaScript.htm

hello,

thank you for this great indicator. I would like to ask if it can be modified to keep all trend lines, not they disappear.

It is ilustrated on attached picture.

thanks for your help.

go to download section , look for the tape indicator, it draws channel without deleting old t/l.

[toddaclark]

I use this AutoTrend Line indicator and like it a lot.

I'm trying to figure out how to keep the arrows from disappearing when a new trend line is drawn. I would like to be able to look back thru the whole day on my 233 tick chart of ES and see what trendlines broke.

Can someone help find where to change the code to make that happen?

Thanks,
TC

[NinjaTrader_Josh]

You will likely need to examine the code and submit with unique names for each drawing object so it does not overwrite the old one.

[toddaclark]

Josh,

Thanks for your reply. I've attached the indicator.

I've looked at the code but don't see where I should submit unique names for the arrows. I'm not sure what to do.

Would it be possible for you to open the code, make the change and re-attach the revised code?

TC

[NinjaTrader_Josh]

Look at all the areas that have DrawRay or DrawArrowDown. They all have non-unique string names. Give them unique string names if you do not want them to overwrite each other.

Bear in mind you need to then mess around with the RemoveDrawObject() lines. Unfortunately those are the only pointers I can give you to get you in the right direction. I cannot amend the indicator for you at this point in time.

[designer]

Creating a strategy with AutoTrendlines....In the Strategy Wizzard I am trying to create a strategy where i enter a position when price close crosses above the trendline...but for some reason does not seem to be triggering the orders when the strategy is added to the chart. Am i doing something wrong? Please see screenshot attached.
Thanks

[NinjaTrader_Bertrand]

designer, this is expected since the plotted trendlines can't be used directly in the wizard to generate auto trades. For this you unfortunately need advanced custom code giving your the exact trend line values to trigger trades from.

[trader1512]

has anyone modified the code to keep the trend lines and arrows on the chart after trend ends?

[designer]

Not that am aware of...

Hi there,

Can somebody help me on converting CS File to Mq4. I've downloaded it but still no avail in using it.

Thanks & cheers.

[NinjaTrader_Bertrand]

mat j, welcome to our forums! Unfortuantely we can't assist you on converting your NinjaScript files to MQ4.

[winja]

I tried to import the AutoTrendLine.zip from post #1 but get an error message -
Import Failed. There are NinjaScript files in the imported NinjaScript Archive File that hav programming errors. These errors must be resolved before you can import the NinjaScript Archive File.

Any suggestions? Thanks
winja

[nkhoi]

you need to go to your indicator folder, move the most recent indicator to somewhere else, also delete user define file, try compiling again, keep doing that until you are able to compile then you know which indicator gives you the trouble.

any one be able to import auto trendline file into NT7 Beta??

Mike, I believe some people can and are indeed able to import auto trendline file into NT7 Beta....at least that is my understanding...

[Mike12345]

Hi Bertrand

Regarding this code, What I have to do to unlock the trend line just in case. I try to move it and give me a red lock sign, I try to save it as unlock but it is going back next tick to be locked.


Thanks
Mike

[NinjaTrader_Bertrand]

Try adding this below to Initialize() -


AllowRemovalOfDrawObjects = true;

[Mike12345]

Thanks Bertrand

I try this and it is not working on calculate on bar close false or true.
just I want be able to move the TL in Auto Trendline indicator by the mouse.

Thanks
Mike

[NinjaTrader_Bertrand]

Sorry Mike, to unlock the drawn objects, you can set locked to false programmatically with this snippet here in the OnBarUpdate() code portion - http://www.ninjatrader.com/support/helpGuides/nt7/idrawobject.htm

[Mike12345]

Thanks Bertrand

I did that and I have been able to move the past TL not the current one??

Thanks Again

Mike

[NinjaTrader_Bertrand]

Sorry don't follow you, if I apply this on the code I referenced on # 51 I see one current ray drawn and it's unlocked i.e. freely movable then after this snippet is added.

[Mike12345]

Thanks Bertrand

Yes I add on # 51.

I attach a copy of the code, I may missing something, thanks for help me.
if you don't mind would you please check it.

Thanks

Sorry it deosn't let me attach the full code here but if I get you email I will email it to you

[NinjaTrader_Josh]

Mike,

In your code you will need to set the lock property for the object to false.

Please see the example here: http://www.ninjatrader.com/support/helpGuides/nt7/idrawobject.htm

[Mike12345]

Thanks Bertrand

I view the code again but I didn't find anything related to unlock, Do I missing anything.
Thanks
Mike

[NinjaTrader_Austin]

Mike, if you are using CalculateOnBarClose = true, you will have to wait until the most current bar is completed (or for a new bar to start, it is the same event) before the current trend line will be unlocked.

If CalculateOnBarClose is set to false, you will just have to wait for the next tick to come in before the trend line will be unlocked.

[Mike12345]

Thanks Bertrand
I have CalculateOnBarClose is set to false, and I wait a 2 or 3 tick and after that one TL is moving and the current one is locked.
is any way to load the code or send it for you.
I run NT 7/17

Thanks for helping
Mike

[NinjaTrader_Bertrand]

Hi Mike, you can send the code you use to support at ninjatrader dot com to my Attn, so I can take a look - thanks.

Thanks Bertrand
I will do so

Has anyone been able to use this awesome indicator on something other than price, i.e. Stochs PeriodK or something like that? It could make for a mean divergence indicator.

Hi

Since last week I can not see the lines of this indicator only the Arrows.
I already reimported the indicator from the forum and imported again into the NT but didn't fix it.

I have NT 6,5.1000.16

Do you know how fix this?

Thanks

[NinjaTrader_Bertrand]

Rita, any errors in the log tab of your Control Center as this happens?

[RitaPacheco]

No errors on the log tab of myControl Center

I can see arrows but not lines
