I output the value, Spread should be = ASK - BID
MT4 Build 1065
That is correct, 21 points displayed as a double.
Use DoubleToString() in your Print.
I am confused,
ASK-BID should be 0.00021,
but it shows 0.000209999999998214..
I store the ASK-BID in array, and output it (0.00020999999)
I have already given you the answer.
