MakarFX:

use the readings to build the logic for your indicator

No, it doesn't work like that.

here . 1 indicator always shows a number - 2147483647. as soon as a signal is received, it shows a different number on one of the buffers. This I have figured out.

But the second indicator always shows either 0 or 2147483647 on 2 buffers simultaneously

I think I've figured it out. It's supposed to be like this 
  
     if (in1b<2147483647 && in2b>0 && in2b<2147483647)
           Sell[i]=low[i];
     if (in1s<2147483647 && in2s>0 && in2s<2147483647)
            Buy[i]=high[i];

no specifics are needed in this case, i.e. just if >0

but what's in the buffers when there's no signal. i don't think >0 will work here. but i'll try it now

the first indicator has the value EMPTY_VALUE when there is no signal

do the following

   if(iCustom(NULL,0,"in1",1,i)>0&&iCustom(NULL,0,"in1",1,i)<Bid*2&&iCustom(NULL,0,"in2",0,i)>0) // индикатор стрелка вниз

   if(iCustom(NULL,0,"in1",0,i)>0&&iCustom(NULL,0,"in1",0,i)<Bid*2&&iCustom(NULL,0,"in2",1,i)>0) // индикатор стрелка вверх
 

Please help me to solve this problem with the tester. I am testing position opening for CME on EUR/USD futures

On the rise of the market in the tester I open a long position on the breakdown with my stop and the trade gets a ticket #2. The market goes up and the next position is opened with a stop and the trade gets ticket #3 in the tester.

When the market goes against the position #3 and reaches its stop, ideally #3 should close at the stop, and #2 should stay there, waiting for the price to reach the stop #2. But for some reason, when stop #3 triggered, the tester closes position #2 as well.

The code for mql5 is 

MqlTradeRequest request={};
MqlTradeResult  result={};
                                 
request.action = TRADE_ACTION_DEAL; //Вход рынку
request.symbol = Symbol();
request.volume = 1.0; //Кол-во фьючей
request.type   = ORDER_TYPE_BUY; //Купить
request.price  = SymbolInfoDouble(Symbol(),SYMBOL_ASK);   
request.sl     = NormalizeDouble(sl,5); // Стоп

bool check     = OrderSend(request,result);

The code for mql5 is


I do not know mql5, but I do not see where there is a choice of order to close
 
MakarFX:

the first indicator has a value of EMPTY_VALUE when there is no signal

should be done like this

Yes, that's right. That's it. Thank you very much.

 

I think the reason for the tester's behaviour has become clear. The type of demo account the robot is testing on is Netting. Therefore, if the stop specified when opening position #3 is triggered, it will close the entire volume of the position. Therefore, at the stop from #3, it closes #2 as well, even though it had its own separate stop set for it when it was opened.

With Hedging account type, everything would work like in good old mql4.

The code for mql5 is as follows

You should not use stops. Instead of using stops, we should place pending orders of the opposite direction.
