Thank you for your help)
 

Please help!

I want to use the opening time of the current candle in my robot but the compiler gives me the error 'CopyTime' - no one of the overloads can be applied to the function call. Why is it so?


double TimeOpen[1];

if(CopyTime(Symbol(),0,0,1,TimeOpen)<0)
     Alert("Ошибка в CopyTime");

1. You have to paste the code correctly (I have already fixed your paste)

2. The time should be copied to the datetime array

   datetime  TimeOpen[1];

   if(CopyTime(Symbol(),0,0,1,TimeOpen)<0)
      Alert("Ошибка в CopyTime");

Good evening, forum users!

Who can suggest with this question.

I have uploaded my own symbol quotes, there is no such base on which I trade in MT.

How to make a deposit in my base for the tester?

 

Dear Members of the Forum!

Please advise!!!

The MetaTrader 5 window shows the Bid& Ask values, which (as far as I understand) determine the win/loss.

However, when I try to use minute quotes of the history to test my strategy, these quotes do not contain the Bid and Ask values, but give the values " OPEN", "HIGH" "LOW", "CLOSE", "TICKVOL","VOL", "SPREAD". It is not clear at all how to get Bid and Ask from these values, as well as how the spread is calculated from these values.

 

Dear forum members help please!!!

I want to assign a price step to a variable:

int V=SymbolInfoInteger(Symb,SYMBOL_POINT);

error: 'SymbolInfoInteger' - no one of the overloads can be applied to the function call

What's my error again?


 

Hello.

There is a CArrayObj class in the standard library. An array of pointers to objects of type CObject and its descendants.

What if I need to put objects of type CArrayObj in the array? What to do? Create a new class of type CObject, which will contain a pointer to the object CArrayObj, and then add it to CArrayObj?

Just add another CArrayObj array to the CArrayObj array: Add()
