In MQL4, I have the following line int OP_TYPE = int(0.5((1+f)*OP_BUY+(1-f)*OP_SELL)); which gives the error: '+' - some operator expected . What am I supposed to do in this case?

You cannot infer calc types using MQL4, make sure you explicitly type your calculation in full. int OP_TYPE = int(0.5*((1+f)*OP_BUY+(1-f)*OP_SELL));
