How to use || at int?

Ahmed Abd El Aziz 2023.04.09 15:10

Hello

I am a beginner, i just try to say:

for ( int j = 1; j <= 900; j++ )

if(Close[i] > Close[1+J])

It is mean that close 0 is above all closes of the last 900 candles,

but i need to say that close 0 is above close 1 or above close 2 ... to the last 900 candles!

when i write:

int x= 1 || 2 || 3 || 4;

if(Close[i] > Close[x+i])

it dose not work of course and i know that, but i need something like this to use!

I don’t understand what it is that you are trying to do

I try to short this conditions:

if ( Close[i] >  Close[1+i]
||  Close[i] >  Close[2+i]
||  Close[i] >  Close[3+i]
||  Close[i] >  Close[4+i]
||  Close[i] >  Close[5+i]
||  Close[i] >  Close[6+i]
||  Close[i] >  Close[7+i]
||  Close[i] >  Close[8+i]
||  Close[i] >  Close[9+i]
||  Close[i] >  Close[10+i]
||  Close[i] >  Close[11+i]
||  Close[i] >  Close[12+i])

It may be reach to Close[900+i]

Any Help?

bool is_true = false;

for(int cnt = 1; (cnt <= 900) && !_StopFlag && !is_true; cnt++)
{ is_true |= (close[i] > close[cnt+i]); }

Why did you post your MT4 question in the MT5 General section instead of the MQL4 section, (bottom of the Root page)?
General rules and best pratices of the Forum. - General - MQL5 programming forum? (2017)
Next time, post in the correct place. The moderators will likely move this thread there soon.

You have been repeatedly told where to post your MT4 question. Why do you insist in violating the rules?

BTW, the answer is one function call and you have two choices.

Sorry Dominik, that is not the same as all candles are in order, which will never happen.

void OnStart()
  {
   bool conditionCheckResult = thisCondition(Close, 1, 900);
  }

bool thisCondition(const double &serie[], int index, int depth)
  {
   int limit = index + depth + 1;
   if(limit > ArraySize(serie))
      limit = ArraySize(serie);
   for(int i = index + 1; i < limit; i++)
      if(serie[index] > serie[i])
         return(true);
   return(false);
  }

P.S. not tested

Is that a mystery?

William, I don't understand. Could you please explain what you mean with "in order"?

for(int cnt = 1; (cnt <= 900) && !_StopFlag && !is_true; cnt++)
{ is_true |= (close[i] > close[cnt+i]); }

I misread that previously. You get true if close[i] is not the lowest value. Not what OP wants.

Only for you. “As requested, live in ignorance.”
