Thank you very much for this. I've downloaded the code and will check it out tomorrow.

Josh, thanks. This is very useful. I would like to apply this to other indicators. Can you explain what is necessary to modify in the ninjascript to plot an indicator as an overlay on price?

Thanks,

Steve

There is actually a decently advanced routine to accomplish this. I overrode the Plot() method to get it to plot the way it does. Basically I had to create my own "scale" on the price panel based on pixel count of the height/width of the window.

[stevestrading]

Thanks for the explanation. Sounds like it's more complicated than I thought. You wouldn't by chance want to program the Ninjatrader TRIX indicator to plot in overlay mode would you? If I thought I had the expertise, I'd try to do it myself.

Thanks,

Steve

Unfortunately I just don't have the spare time to commit to handling custom indicator requests at the moment. Maybe someone from the community can hack up my code for you.

[stevestrading]

I understand, no problem.

I also want the %K overlaid on the price.
I downloaded the zip files but I cannot tell what format the file is in.

Any ideas would be appreciated
many thanks

[NinjaTrader_Ray]

You need to import the Zip file.

Josh,

I have applied this method to an indicator I wrote, and it works like a charm.

My question is how would I modify the plot method to plot things like trendlines or text objects (from calls to drawLine() and drawText()) on the indicators scale?

I would think this is similar code, in that you would iterate thru the collections of drawing objects and plot them based on the indicator scale. Any help would be greatly appreciated.

[NinjaTrader_JoshP]

I'm not sure if I understand what you are trying to do exactly, but if you are trying to use the draw objects on the price panel you can already do that. Setting the property DrawOnPricePanel to true in the Initialize() method of your indicator should do the trick.

I have an indicator that is similar to your stochastic, and I have used your plot code to plot it on the price panel but using a different scale. In that same indicator, I would like to do something like draw a trendline between specific peaks of the indicator or place a text object at a peak, again on the indicator scale not the price scale.

In the indicator, the plot method was overriden to get the indicator on the price scale. I am asking how would I get other draw objects to show up on the price panel but with the indicaotrs scale.

[NinjaTrader_JoshP]

I do not remember the exact algorithms I used in the overlay, but the general idea is to normalize the drawing field and then plotting to absolute pixels. You will need to do the same with the draw objects.

Unfortunately the answer is not a simple one and beyond the brief overview above it is beyond the level of support we can provide due to bandwidth issues. Thanks for understanding.

[aslane]

Understood. I can try to figure it out if you can at least point me to how to access the collection of objects that have been added via the drawLine or drawText methods. Thanks.

Unfortunately this is beyond what we provide support for.
