The type of result is a double number, and I want to convert the double number to an integer number, but the number of digits after the decimal point of the result corresponding to each symbol is uncertain. I really don't know what to do other than doing it differently depending on the symbol.

Q : "How to convert the value of iHigh() - iLow() to integer?... doing it differently depending on the symbol." A : Yes, we need to do it differently, depending on each the symbol. Something like this may be a way to handle this : ... int iSymbolSpecificDIGITs = SymbolInfoInteger( Symbol(), /* here, or OrderSymbol(), if looping OrderBook */ SYMBOL_DIGITS ); ... int iHiLoDIFF = (int)( MathPow( 10, iSymbolSpecificDIGITs ) * _high ) - (int)( MathPow( 10, iSymbolSpecificDIGITs ) * _low );

Main thing is to add NomalizeDouble to the result and add Digits in the bracket to sum everything up: Alert(NormalizeDouble(result,Digits)); Or Print("result:" + NormalizeDouble(result,Digits));
