Anyone know how I can paint the bar on my charts?

First:
Define your colors, say, upColor and downColor.

private Color upColor = Color.Blue;
private Color downColor = Color.Red;


Then:

if (whatever your up condition is)
{
BarColor = upColor;
// If you also want to color the outline and the wick, add this (assuming you are using candles):
CandleOutlineColor = upColor;
}

etc. for down or whatever.

Bob.

PS, I assumed when I wrote this that you were writing an indicator and just needed the code for a paintbar. If you're not doing the coding, but would like an indicator written, the best place to ask is the free indicator thread:

Want your NinjaTrader indicator created, free? Hey guys, I thought many of you would enjoy and benefit from this thread. My intention is to have each poster reply and describe in as much detail as possible an indicator they want created for NinjaTrader. The programmers on the forum (there are many), …

You would need to specify exactly what you want the indicator to do....

Hope one of these answers addresses what you need.

@Colin45

many indicators in the download elite section already have this, and show those conditions on the sample chart window of the description,

if you're not paid up as an Elite, now would be an excellent time to consider it, as the participation is well worth the effort....

ADXVMA comes to mind,
then there are the combination Renko or Range with Bands (bollingers, kiplingers, hippo bands and hippie bands too)

have fun scrolling through and test out a few,

you'll find your time very well spent.

its one of the best features of NexusFi (formerly BMT)

Hi Kronie,

Thx very much indeed, I will have a look at this...
