Is there a way to analyse individual candle?

[Art09]

Hi.
Is there a way to write some code that would apply to the particular candle/bar and not the whole chart please? I wrote a simple code that draws arrows when the Stoch. cross abv/below... Is there a way to analyze and write some conditions that would apply to only cross candle/bar please? E.g. if cross abv/blw true then the program draws the arrow. Then I'd like to be able to write a code that would apply to only cross candle/bar and not to the candles before or after this particular cross. Is this possible?
Thank you very much.
Regards, Art.

Art09, this is definitely possible. You will just have to specify exactly what the conditions are for the "cross". You could do something like:

if (Open[0] < Stoch && Close[0] > Stoch)
// this current bar has crossed the stoch line, do something
DrawArrowUp(...);
