Hi, I try to create an EA with MQL5 that pulls values from another indicator to use as signals for buying and selling. However, I get this [error:',' - open parenthesis expected.] , I don't know what the problem is , would you please help me to solve this error?

This is what is shown in line 60 = int bars = Bars;

[Conor Mcnamara]

  // Check how many bars are available
    int bars = Bars;

that's the problem, this would only work in MQL4 unless you used cross platform code in MQL5

change to

  // Check how many bars are available
    int bars = Bars(_Symbol, _Period);

int bars = Bars(_Symbol, _Period);

Thank you for your assistance in this matter :]
