Help - issue in the code

[EVERTON GALVES]

I need help in this case: ERROR: '-' - open parenthesis expected  73: 43

{
   // Calcular médias móveis
   int limit = MathMin(rates_total, (Bars - prev_calculated));
   if (limit <= 0)
      return (0);

   for (int i = prev_calculated; i < limit; i++)
   {
      EMA9Buffer[i] = iMA(_Symbol, 0, EMA9_Period, 0, EMA_Method, i);
      EMA21Buffer[i] = iMA(_Symbol, 0, EMA21_Period, 0, EMA_Method, i);
      EMA50Buffer[i] = iMA(_Symbol, 0, EMA50_Period, 0, EMA_Method, i);
      EMA200Buffer[i] = iMA(_Symbol, 0, EMA200_Period, 0, EMA_Method, i);
   }

Please always use the CODE button (Alt-S) when inserting code.

Unlike in MQL4, in MQL5 there is no predefined variable called "Bars". There is however a function called "Bars()".

Also, unlike MQL4, in MQL5, the indicator functions like iMA() return handles and not the data directly, and you have to use CopyBuffer() instead to get the data

Is this ChatGPT generated code?

ChatGPT (or other A.I.) generates horrible code, mixing MQL4 and MQL5. So, if it is the case, then please use the Freelance section for such requests — https://www.mql5.com/en/job

 int limit = MathMin(rates_total, (Bars(Symbol(), Period()) - prev_calculated));

or else

 int limit = MathMin(rates_total, (rates_total - prev_calculated));

I had a test, and this is true. It's strange

or else

int limit = MathMin(rates_total, (rates_total - prev_calculated));

This could be simplified more:

int limit = rates_total - prev_calculated;

But that doesn't make sense because what follows is this:

if (limit <= 0)
   return (0); // The next time OnCalculate is called, prev_calculated will be 0

Actually, nothing good should be expected from the generated code😄
