January 08 S&C article "Profit Locking And The Relative Price Channel"

[NinjaTrader_Ray]

Attached is the "Bear Range Trailing Stop" indicator as discussed in the January 08 S&C article authored by Leaon Wilson titled "Profit Locking And The Relative Price Channel".

This indicator is for NinjaTrader Version 6.5 or greater.

To install:

1. Download the file to your desktop
2. Start NinjaTrader
3. Select the menu File > Utilities > Import NinjaScript
4. Select the downloaded file saved to your Desktop

This particular .zip is giving me an error when importing. Anyone else having issues? I'm quite interested in the idea behind this one.

Are you using NinjaTrader 6.5?

[jonesenberg]

Apparently not?! Working on that now and will report...

[jonesenberg]

Upgrading to 6.5 surely did the trick, but interestingly, LinRegSlope no longer plots.

[NinjaTrader_JoshP]

That is because of the syntax change to the Slope() function in NT6.5. Go bring up your indicator and remove the CurrentBar references.

If it use to be "...CurrentBar - Period, CurrentBar)" change it to just "...Period, 0)"

[jonesenberg]

The applicable lines read:

{
LRSlope.Set(Slope(LinReg(Period), CurrentBar - Period + 4, CurrentBar));
}


So...:

{
LRSlope.Set(Slope(LinReg(Period), Period + 4, 0));
}

? And thank you for the help, Josh.

Right. Btw. Where did you get LinRegSlope? I have it on my comp too, but forgot what I made it for haha.

Awesome, works like a charm. It comes from the Dec '07 S&C release, paired with the rSquared indicator.

Thanks again. I'm sure I'll be back for more.

LinRegSlope

Per the below message I made the change in the code for the LinRegSlope indicator and saved it and closed the window -- see attached image. However the indicator does not display on the chart. I can choose it but the panel is blank. Did I leave out something I need to do? I'm not familiar with code btw.

The applicable lines read:

{
LRSlope.Set(Slope(LinReg(Period), CurrentBar - Period + 4, CurrentBar));
}


So...:

{
LRSlope.Set(Slope(LinReg(Period), Period + 4, 0));
}

? And thank you for the help, Josh.

Hello,

Try adding if(CurrentBar < Period + 4) return; right after OnBarUpdate().

You can't access a bar that does not exist yet.

LinRegSlope

I still can't get the indicator to plot..what am I doing wrong? Also is there a way to plot angle value of the Linear regression Line? Thanks!!


{
if(CurrentBar < Period + 4) return;
LRSlope.Set(Slope(LinReg(Period), Period + 4, 0));
}

[NinjaTrader_Ray]

Are there any error messages in the Log tab of the Control Center window when you apply this indicator to a chart?

There are no ways to access an angle value for lin reg.

This looks more like the correct Linear Regression Slope

The Slope for the Linear Regression posted by anachronist here:

http://www.ninjatrader-support2.com/vb/local_links.php?catid=1&sort=N&pp=15&page=7

( LinRegSlopeSFX - Linear regression slope super fast calc with option for exponential weighting )

matches the Slope indicator in the orignal S&C article (I plotted historical charts and they matched the ones in the article). IMO his formula should replace the one in Ninja

Thanks for the link and input bkout!
