Hi all, I have this mq4 file found in this thread: https://www.forexfactory.com/showthread.php?t=343533 i used to use it with mt4 without any problem but now when i rent vps from MQL5, upload this indicator and use it as a part of an ea, it has zero divide error {image} Can any coder help me fix this problem Thank in advance. {file}

{quote} Zero divide error can not happen in line 191 of that code (there is no division at that line at all, neither it has 49 chars) Check the code that you actually use for errors not the code that you posted

int limit = 0;

I know this is an old thread, but I have a code that gives me zero devide error and I thought continuation of this thread is better than trying to open a new one? here is the code int limit = 0; int values_to_copy = 0; calculated = BarsCalculated(ExtSlowMaHandle); if(prev_calculated==0 || calculated!=bars || rates_total>prev_calculated+1) { if(calculated > rates_total) values_to_copy = rates_total; else values_to_copy = 0; } else { values_to_copy = (rates_total - prev_calculated) + 1; limit = rates_total - values_to_copy; } for(int i = limit; i...

 if((zeta * 100)!=0)
  eta[i] = (delta[i] - epsilon) / zeta * 100;
  else eta[i] = 0;
