Just wondering about the sample EAs in the metatrader 5 platform. Why are their codes very short? Like for example ExpertCrossMA's code, it contains only a few lines of code while the sample codes in the articles are so long and detailed? What does these two lines mean:
if(!ExtExpert.InitSignal(new CSignalCrossMA)) return(-2);
if(!ExtExpert.InitMoney(new CMoneyFixedLot)) return(-3);
Can someone kindly explain it to me? I'm just a beginner programmer and I'm trying to study sample codes as my reference.
Thanks in advance!
