how to color a specific candle given certain criteria?

[james malone]

In my ea, i need to color a specific candle should it meet certain criteria. I have basic understanding of mql5.

I have written the following and feel like i'm either not understanding something here or making a mistake. 

In the OnTick() section...

double close[];
ArraySetAsSeries(close,true);
CopyClose(_Symbol,_Period,0,3,close);

if((close[1] > close[2]) && (/*other criteria*/))
{
//color a specific candle
  PlotIndexSetInteger(0,PLOT_LINE_COLOR,0,clrBlack); //not sure if this is right to color a candle
}

To color candles - you must use an indicator, not an advisor.

I recommend using the DRAW_COLOR_CANDLES  style.
