Hello everyone!

Thanks to everyone who helps newcomers, not sparing their time, despite the fact that altruism has lost its value these days.

I ask for help from forum users, I've read all of Igor's thread, but have not found what I need, so I decided to write here.

And function I suspect is not complicated and somewhere already is, but...

How to calculate the maximum/minimum of the current(previous, ...) daily (weekly, ...) candle a MINUTE(5,15,30,60, ...) BACK?

I will be very grateful to altruistic professionals.

:)))- that's funny.

Read on - you'll find many interesting things. :)))

How to get Open[] of the current chart but not of the current timeframe?

It's a sin to laugh at .....)))


I read it... "Volumes of other timeframes are not modelled"

I must have misstated the point of the question then... I'll try to simplify it:

How do you calculate the maximum/minimum of the current candle a MINUTE LATER?

 
TarasBY:
iOpen().


Thank you

It's easier to laugh than to read (let alone "dig in")... :)))

Trying to solve the problem in code:

    //---- Находим последний расчётный бар на нужном нам тамфрейме
    int li_Shift = iBarShift (Symbol(), PERIOD_M1, iTime (Sumbol(), PERIOD_D1, 0)),
        //---- Ищем на нужном промежутке номер бара с High
        li_Bar = iHighest (Symbol(), PERIOD_M1, MODE_HIGH, li_Shift, 1);
    //---- Получаем значение High
    double ld_HIGH = iHigh (Symbol(), PERIOD_M1, li_Bar);

In the image and similarity with the minimum can you handle it?! ;)

P.S. Since in the price history we have a discreteness with a minimum size of 1 minute, it is correct to say not "a minute ago", but "not counting the last minute".

Hello guys, please help with the indicator sAccelerator.mq4. I want to make an alert when the 0 line is crossed, and the alert to remove the repaint, it does not work, and in mql frankly I do not understand.

Gentlemen, please advise how to find the average ticks in a bar. I assume the following:

Average[i] = (total amount of ticks of bar[i])/Volume[i]; How to find the total amount of ticks of the desired bar?

 

Please tell me what I'm doing wrong. I am trying to make a simple indicator:


  {

   int limit,i;
   double last;
   int counted_bars = IndicatorCounted();
   //---- check for possible errors
   if (counted_bars < 0) 
       return(-1);
   //---- last counted bar will be recounted
   if(counted_bars > 0) 
       counted_bars--;
   limit = Bars - counted_bars;
//----
   for(i=limit; i>=0; i--)
   {
      double OptClose = Close[i]*10000;
      if (MathMod(OptClose,step1)==0)
      {
      Buffer0[i] = Close[i];
      last = Close[i];
      }
      else
      Buffer0[i] = last;
   }

//----
   return(0);
  }
//+------------------------------------------------------------------+

It works in the chart window, but when I try to test it in the Expert Advisor, it either draws whatever it is or "no steps".
