Error code : '&&' - program is too complex

New comment
 

Hello


(At MQL5)

When i try to input 5000 conditions in my code it gives me this error :

'&&' - program is too complex


After i remove some conditions then the code work perfectly


How can i fix this error without removing any conditions?


is mq5 is a limited conditions ?


 
  1. If you have 5K conditions, the problem is your brain. Do not cut and paste identical conditions. Show us an example if you want help.
              The XY Problem


  2. Simplify and combine.
    bool c0010 = condition01 && condition02 … && condition09;
bool c0020 = …
⋮
bool C0100 = c0010 && c0020 … && c0090;
bool C0200 = …
⋮
bool c5000 = c1000 && c2000 …

I want to repeat the next condition 5000 times every time change it to become like this


  || (Close[1+i] > Open[1+i]&& Close[2+i] > Open[2+i]&& Low[1+i] > High[3+i]&& RSI[3+i] < 30)
|| (Close[2+i] > Open[2+i]&& Close[3+i] > Open[3+i]&& Low[2+i] > High[4+i]&& RSI[4+i] < 30)

|| (Close[3+i] > Open[3+i]&& Close[4+i] > Open[4+i]&& Low[3+i] > High[5+i]&& RSI[5+i] < 30)


After i do this 5000 times its gives me that error


How can i use this "bool c5000" in this case?

Just use a loop:

bool conditionMet = false;
for (int j = 0; j < 5000; j++) {
  if (Close[j+i] > Open[j+i] && Close[j+i] > Open[j+i]&& Low[j+i] > High[j+i]&& RSI[j+i] < 30) {
    conditionMet = true;
    // Break out of the loop.
    break;
  }
}

if (conditionMet) {
  Buffer1[i] = Low[i]; //Set indicator value at Candlestick Low
} else {
  Buffer1[i] = EMPTY_VALUE;
}

You are the best

I did it. Thank you very much
