[pekele4u]

Please how can i get the color of Heiken Ashi, that is if it is white(buy) or red(sell) using iCustom function.

Thanks in advance.

You can just use the calculation itself.

It's in the indicator.

pekele4u: how can i get the color of Heiken Ashi, that is if it is white(buy) or red(sell) using iCustom function.

1. There are no colors in iCustom, only values. If the close is above the open it's white, otherwise it's not. Was that so hard? When in doubt, think.
   

2. Just get the value(s) of the indicator(s) into the EA (using iCustom) and do what you want with it.
   You should encapsulate your iCustom calls to make your code self-documenting.
