Maybe I didn't understand my question.

Being on the M1 period chart I want to fill the buffer if on the M5 period, the " Stochastic" indicator line is now above the 55 level.

input ENUM_TIMEFRAMES   TimeFrame2  =  PERIOD_M5; //ЭТО ВО ВНЕШНИХ Н
////////////////////////////////////////////////
       for(int i=limit; i>=0; i--) {
      int bar_sto2_0=iBarShift(Symbol(),TimeFrame2,iTime(Symbol(),TimeFrame2,i));
      int bar_sto2_1=iBarShift(Symbol(),TimeFrame2,iTime(Symbol(),TimeFrame2,i+1));
    
      double sto2_0=iStochastic(Symbol(),TimeFrame2,kperiod2,dperiod2,slowing2,MODE_LWMA,STO_CLOSECLOSE,MODE_MAIN,bar_sto2_0);
      double sto2_1=iStochastic(Symbol(),TimeFrame2,kperiod2,dperiod2,slowing2,MODE_LWMA,STO_CLOSECLOSE,MODE_MAIN,bar_sto2_1);
    
      if(sto2_0>55.0)
       {
      BufferUP[i]=low[i]-distance*MyPoint;
       }
      
      if(sto2_0<44.0)
       {
      BufferDN[i]=high[i]+distance*MyPoint;
       }

      Comment(sto2_0);
       }

In the comment the current value is correct with M5, but on the history the arrows put not on condition, chaos.

What can it be?

In the " basement" the stochastic from M5

The arrows are circled not according to the signal

I am writing an Expert Advisor that simultaneously places two StopOrders, one to sell and one to buy.

How do I write the condition that when one StopOrder triggers, the second (opposite) one is deleted?

Thank you.

Thank you.

The condition is simple. When a StopOrder triggers, a position appears in the market, it means that we should track the position and if it exists, we should delete the opposite order.

This is a piece of code for thought)

void DeleteOppositeOrders(string sy="", int op=-1, int mn=-1, color cl=clrOliveDrab) {
  bool b, s;
  switch(op) {
    case OP_BUY : b=ExistPositions(sy, OP_BUY , mn); break;
    case OP_SELL: s=ExistPositions(sy, OP_SELL, mn); break;
  }

  if(b) {
    DeleteOrders(sy, OP_SELLLIMIT, mn, cl);
    DeleteOrders(sy, OP_SELLSTOP , mn, cl);
  }
  if(s) {
    DeleteOrders(sy, OP_BUYLIMIT, mn, cl);
    DeleteOrders(sy, OP_BUYSTOP , mn, cl);
}}
 
Vitaly Muzichenko, as far as I understand, you now need to add theExistPositions andDeleteOrders functions

Yes, you do.
 
RichLux:

You don't have to write them, they are bothready-made

Well ..., for educational purposes it's quite useful ...

For practical purposes, it's very expensive to run cycles in each function.

For practical purposes, it is very costly to run cycles in every function.

Therefore I have not attached at once and have described and attached only the logic of the "closing of the opposite" )
 

What to do if the stop/stop is 200

but

tp=NormalizeDouble((price+(TakeProfit*_Point)),Digits);

on a dollar-yen will yield 317.000 at the exchange rate of 117.000

the expected result is 117.200

Why so many brackets? It's a matter of taste, of course, but still too much.

tp=NormalizeDouble(price+TakeProfit*_Point,_Digits);

Values are substituted incorrectly if the result is incorrect in the output, because this line of code will calculate everything correctly, even with extra parentheses.
