CCI Color Shading Problem

[daiyqchenyh]

Hello,

I'm trying to make a simple modified CCI indicator.
The function is to shade the area between CCI and level 100.
But the output seems it drift to the left.
Could anyone give me some advice?
Thanks for any help

The Drawing Part Code:
Plot0[0] = CCI(Period)[0];
top[0] = Plot0[0];
if(top[0] < -100)
{
Draw.Region(this, "Region" + CurrentBar,1, 0, top, -100, Brushes.Red, 70);
}
else if(top[0] > 100)
{
Draw.Region(this, "Region" + CurrentBar,1, 0, top, 100, Brushes.Green, 70);
}

Hello daiyqchenyh,

Thank you for writing in. Please make sure to keep NinjaTrader 8 inquiries in the NinjaTrader 8 section of the forum: http://ninjatrader.com/support/forum...splay.php?f=57

To make sure the full segment gets covered, you cannot be drawing the region using bars. It will rarely happen where the first bar will line up with the beginning of the region. I recommend drawing using the DateTime override:

Draw.Region(NinjaScriptBase owner, string tag, DateTime startTime,
         DateTime endTime, ISeries<double> series, double price, Brush areaBrush, int areaOpacity)

As an example, for the first bar of a red segment, where CCI(Period)[0] < -100 && CCI(Period)[1] >= -100, you need to do some math to determine the actual DateTime where the CCI would hit -100. This will usually be in between bars.

Then you would use a similar procedure for the first green segment, and the lest red and green segments.

Please let me know if I may be of further assistance.

Apologies for dragging up an old thread.

I'm trying to follow up on the advice from Michael M: As an example, for the first bar of a red segment, where CCI(Period)[0] < -100 && CCI(Period)[1] >= -100, you need to do some math to determine the actual DateTime where the CCI would hit -100. This will usually be in between bars.

Is anyone able to provide an explanation or an example of how one would actually perform that calculation?

Thanks!

PatrickH, Hi

I can't recall exactly where but a little while ago Harry discussed the same situation in which there is a shift in shading region between two lines unless the correct mathematical crossover is used by Ninja.

Harry has already resolved this issue for his own work, however I think he proposed the method he used as a way for Ninja to improve the Draw.Region method.

I do not recall any followup by Ninja or whether that was considered as a feature improvement for NT8.

A potential Feature Improvement Request is to have Draw.Region method based on actual X-overs.

Cheers.

Hi PatrickH,

Is it safe to assume you are still looking into this?
