fxsaber:

It has been written about many times. Not corrected for some reason.

I've seen it written before about arrows not always being able to be displayed immediately after a transaction. I opened such an application as well. But to have such omissions in the list on the History tab, haven't seen any posts yet.

P.S. And yes, after providing evidence and all the necessary data to reproduce the bug, for some reason a complete ignore for a whole week, although from the beginning responded, refusing to agree that there is a bug.

You need to switch tabs several times, then the history becomes correct. It is very unpleasant during debugging.

Yes, it is very annoying in some cases when developing and debugging trading strategies.

I haven't noticed that switching the tabs has somehow changed the contents of the history list:

Right click and change Deals/Order.

Anatoli Kazharski:

Yes, this is a big hindrance in some cases when developing and debugging trading strategies.

I have not noticed that switching tabs has changed the contents of the history list in any way:

There is such a thing. I save myself with a speed slider and a pause.

fxsaber:

Right-click and change Transactions/Order.

Yes, such actions restore the list of transaction history:

All real symbols in the account are in the form "EURUSD.hello". After creating a custom "EURUSD" will there be no problems when copying from the Signals service?

Please add the following values

ENUM_DEAL_REASON

Identifier	Description
DEAL_REASON_LIMIT	Deal was executed as a result of a limit order triggering
DEAL_REASON_MARKET	Deal was executed as a result of market order triggering
DEAL_REASON_STOP	The deal was executed as a result of a stop order triggering

It seems to be unnecessary. But there are situations in which the order was partially executed, creating a deal,in which case DEAL_ORDER will be found, but it will not be in the history table, since the order is still alive.

In other words, to find out the type of order, which caused the deal, it is not always helpful to refer to the order history. If we don't want to make a mess with searching for orders amongst the "dead and alive" ones, we can simply add more flags of execution (after existing flags) in order to maintain compatibility with ENUM_ORDER_REASON andENUM_POSITION_REASON. At the same time it is desirable to add the same flags toENUM_POSITION_REASON to be compatible

POSITION_REASON_LIMIT  == DEAL_REASON_LIMIT
POSITION_REASON_MARKET == DEAL_REASON_MARKET
POSITION_REASON_STOP   == DEAL_REASON_STOP

A question about OrderCalcMargin came up in a neighbouring threadhttps://www.mql5.com/ru/forum/216697/page3

Test: let's check 2 different ways of calculating the deposit by substituting different opening prices.

#define  TOSTRING(A) #A+" = "+(string)(A)
void OnStart()
  {
   double margin_1=999,price_1;

   Print(TOSTRING(price_1=SymbolInfoDouble(Symbol(),SYMBOL_ASK)));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(OrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(MyOrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print(TOSTRING(price_1=SymbolInfoDouble(Symbol(),SYMBOL_BID)));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(OrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(MyOrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print(TOSTRING(price_1=10.0));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(OrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(MyOrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print(TOSTRING(price_1=1.0));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(OrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
   Print("price_1= ",price_1," margin_1= ",NormalizeDouble(margin_1,8)," ",TOSTRING(MyOrderCalcMargin(ORDER_TYPE_BUY,_Symbol,0.1,price_1,margin_1)));
  }

// Альтернатива OrderCalcMargin
bool MyOrderCalcMargin(const ENUM_ORDER_TYPE action,const string symbol,const double volume,const double price,double &margin)
  {
   double MarginInit,MarginMain;

   const bool Res=SymbolInfoMarginRate(symbol,action,MarginInit,MarginMain);

   margin=Res ? MarginInit*price*volume*SymbolInfoDouble(symbol,SYMBOL_TRADE_TICK_VALUE)/
          (SymbolInfoDouble(symbol,SYMBOL_TRADE_TICK_SIZE)*AccountInfoInteger(ACCOUNT_LEVERAGE)) : 0;

   return(Res);
  }

The OrderCalcMargin function doesn't consider the opening price when calculating the margin

This seems to be related to the exchange rate of the quoted currency, which has to be recalculated for the time and opening price.

If the quoted currency is USD (and the account currency is also USD), then the calculated margin will change according to the opening price.

Is it a Bug or should it be?
