dealing with ODD or double numbers

New comment
 

Hello freinds,

I need your help.

I want the EA to check an operation every two minutes.

The simple way is to do:

  if (   TimeMinute(TimeCurrent()) != 2  && TimeMinute(TimeCurrent()) != 4  && TimeMinute(TimeCurrent()) != 6  && TimeMinute(TimeCurrent()) != 8  &&
         TimeMinute(TimeCurrent()) != 10 && TimeMinute(TimeCurrent()) != 12 && TimeMinute(TimeCurrent()) != 14 && TimeMinute(TimeCurrent()) != 16 &&
         TimeMinute(TimeCurrent()) != 18 && TimeMinute(TimeCurrent()) != 20 && TimeMinute(TimeCurrent()) != 22 && TimeMinute(TimeCurrent()) != 24 && 
         TimeMinute(TimeCurrent()) != 26 && TimeMinute(TimeCurrent()) != 28 && TimeMinute(TimeCurrent()) != 32 && TimeMinute(TimeCurrent()) != 34 &&
         TimeMinute(TimeCurrent()) != 36 && TimeMinute(TimeCurrent()) != 38 && TimeMinute(TimeCurrent()) != 40 && TimeMinute(TimeCurrent()) != 42 &&
         TimeMinute(TimeCurrent()) != 44 && TimeMinute(TimeCurrent()) != 46 && TimeMinute(TimeCurrent()) != 48 && TimeMinute(TimeCurrent()) != 50 &&
         TimeMinute(TimeCurrent()) != 52 && TimeMinute(TimeCurrent()) != 54 && TimeMinute(TimeCurrent()) != 56 && TimeMinute(TimeCurrent()) != 58  ) 


Can you think about simpler way to do it?

 

something like this:

#define ODD  1
#define EVEN 0

int PreviousMinute = ODD;

void OnTick() {
   int CurrentMinute = TimeMinute(TimeCurrent()) % 2;
   if ((PreviousMinute == ODD) && (CurrentMinute == EVEN)) {
      // check operation every two minutes
      Alert("Bi-Minute check ",TimeMinute(TimeCurrent()));
   }
   PreviousMinute=CurrentMinute;
}
 
Use ontimer for a better timer.

  1. Don't paste code

    For large amounts of code, attach it.
  2. While
    if(TimeMinute(TimeCurrent()) % 2 == 0) ...
    would trigger every even minute. You probably only want one trigger per.
  3. What about when there is no ticks during that minute "Free-of-Holes" Charts - MQL4 Articles don't you want to trigger at the next tick?
    static datetime everyTwoMinutes = 0;
datetime now = TimeCurrent();
if(now >= everyTwoMinutes){
  everyTwoMinutes = now + 120;              // Every two.
  everyTwoMinutes -= everyTwoMinutes % 120; // Top of the minute.

I have similar inquiry. I'm a newbie in MQL. I want to get 15m Stochastic value at 1H chart while saving the calculation workload. For this reason, I want to call iStochastic every 15 min to get the closed previous 15m stochastic value.

In this case, does your either #2 or #3 code actually work? I wonder if I can get the the value only when 1st tick of new 15min data is triggered.

  1. On MT4: Unless the current chart is that specific symbol(s)/TF(s) referenced, you must handle 4066/4073 errors before accessing candle/indicator values.

  2. Check for a new M15 bar.

    For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart), volume is unreliable (miss ticks), Price is unreliable (duplicate prices and The == operand. - MQL4 programming forum.) Always use time.

    I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times.
