MQL4 Biggest body between last 20 candle
by last 20 candle i mean, complete candles...
mostafa:
Use a loop to go through the last 20 candles . . . save the MathAbs() difference between the Open and Close, then compare the next difference for the next candle to the last one saved, if it is larger save it instead, repeat for all the candles.
