Tuta.


I don't have one. But there is definitely a file somewhere, I get the information recorded from it.


 

Please help me to compile to mt4

My screenshot shows that the menu is from MetaEditor and your screenshot is from MT.
 
AlexeyVik:

This is the EMPTY_VALUE value

Look for where it is popping up.

Thank you. You have helped me to solve the problem. My indicator, when loaded, calculates bars starting from the first one, not from zero (I did it on purpose), on zero it calculates on tick history, not on historical data. Now when I change timeframe, attach it to the chart and restart the terminal, I reset buffer values to zero on bar 0, problem solved.

Right! Thank you!
 
How can I get the opening price of an order in the history and not the price of an open position if this order has been triggered? In the attached function, if an order has triggered, this order can only be found in positions, so it does not work. And in the positions we have only the open position price but not the order price.
double GetPriceLastCloseOrder(string sy="", int mn=-1) {
  datetime t=0;
  int      i, k=OrdersHistoryTotal(); 
  double r=0;

  if (sy==NULL) sy=Symbol();
  for (i=0; i<k; i++) {
    if (OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)) {
      if ((OrderSymbol()==sy || sy=="") && (mn<0 || OrderMagicNumber()==mn)) {
        if (OrderType()>1 && OrderType()<6) {
          if (t<OrderCloseTime()) {
            t=OrderCloseTime();
            r=OrderOpenPrice();
          }
        }
      }
    }
  }
  return(r);
}  
 

Hi guys, my question is, I can't modify an order. There are two aspects to it, I don't understand the mathematics of modification, so please explain it to me.

The way I see it, SL= IF ORDERSELEKT,Bid-ORDERSTOPLOS*POINT,DIGITS

the second aspect.learned from XBMS video

how i didn't try to change the values of the variables in the tester eror 130 not the right stop loss and shit like this

2016.06.28 21:42:23.402 2016.06.23 00:00 trade RSI inputs: Lots=0.1; Slippage=5; StopLoss=10; TakeProfit=30; RSIPeriod=7; Magic=1087;

although there is a multiplication from digits and function on the case of wrong SL

PLEASE ADVISE!!!

There are two orders in the trading history: 1) SELL № tic 415 STOPLOSS 1.1000 lot 0.01 2) SELL № tic 418 STOPLOSS 1.1000 lot 0.02

I have to assign the variables X=tick, Y=STOPLOSS and B=lot if the Asc price is equal to the STOPLOSS of the SELL order. How to assign first values to the first order, and then to the second one. With me it always assigns a value to the first order.

This topic is designed to help those who already have something written, but it doesn't work quite the way I want it to. Please submit your code so that the others here can see what's wrong and help.

And if you want to be written to order, that's where it's at.

 
burbur87:   I can't modify an order. I'm not familiar with the mathematics of modification.

The modification is described here - it's a textbook chapter
