Automated Creation of Horizontal Lines in Indicators

[mmeninger]

Hello -

I would like to add horizontal lines programmatically to my indicator rather than hard-coding them.

Is there a way to do this?

Thanks,
Mark

Welcome to our forums here Mark - you could use the DrawHorizontalLine command in NinjaScript to achieve this.

Memory leak when using negative numbers in DrawRegion

Hello -

I ended up using DrawRegion instead. It works pretty well and allows me to shade regions.

My indicator is essentially an oscillator which travels around zero.
I want to shade the negative regions.

I ended up doing this:
//DataSeries: regionLevel 1
regionLevel1.Set(theTop);
//the top: a double of 0.01
//the bottom: a double of -0.01
DrawRegion("region", CurrentBar, 0, regionLevel1, theBottom, Color.Black, colourLevel1, 5);

When I use negative values of -0.02 for the top and -0.04 for the bottom, it does not render properly. I get a hack running where I get one portion of the indicator shaded.

However, when I run this code, NT has some sort of memory leak and it gradually consumed 2.5 GB of ram by EO day today (I have 8 GB of ram). I don't want this to happen. Is there a way to shade below zero regions using DrawRegion without the memory leak?

System specs:
Win 7 SP1
8 GB memory
NT 7.0.1000.25 (live)

Thanks,
Mark

Hello Mark,

Thank you for your response.

Can you provide the code for DrawRegion that does not work for negative values?

There should be no issue with negative values, and I am not aware of any memory issues.

I look forward to assisting you further.

I figured it out.
I was instantiating the same Data Series object twice - in 2 separate methods.

That was the culprit.

Thanks for your help!
