I keep getting open error for iCustom.
Heiken_Ashi.ex5 is in indicator folder.
I think I have messed up the handle. Here is handle and heiken_ashi indicator code. There arent any other handle parameters I need are there? Heiken Ashi just changes the candlesticks with a bit of math. There are no parameters needed when you load the indicator except the colour.
HA.Init(_Symbol,_Period,“Heiken_Ashi”); //initiation handle, this is connected to an include file with other indicators thats why its HA.init instead of iCustom(_Symbol,_Period,“Heiken_Ashi”)
HeikenAshi
