Coloring a bar 3 bars back

[wmaria]

I would like to develop an indicator that looks for lower highs and lower lows around a bar before it changes that bar to a certain color.

The problem is that I need at least two bars to plot after the bar I am trying to color before I know if the pattern came true and I need to color the bar which occured 3 bars ago.

Barcolor will not allow me to paint a bar that has already plotted on the chart, is that correct?

Is there any way to change the color of a bar that occured in the past?

Thanks

wmaria, I will have someone get back to you with an answer tomorrow. As far as I know, it isn't possible to color a bar 3 bars back.

wmaria,

Please open up the CandleStickPattern indicator and take a look at how it paints historical bars. Through the use of BarColorSeries.

Great

Thanks for eveyone's help, I will look into these commends.

I tried looking up in Ninja help the ChartControl or BarColorSeries but nothing comes up. Are these commands described in the help file at all?

wmaria,

No, these are unsupported methods, but to achieve what you want is only achievable through this technique.

ChartControl.BarColorSeries[CurrentBar - 3] = Color.Red;

Thanks. That work exactly like I hoped.
