How to get the value of MQL5 program version defined by property# version in the code ?

How to get the value of MQL5 program version defined by property# version?

It turns out that you can't, because inPredefined macro substitutions

Constant	Description
__DATE__	Date when file was compiled without time (hours, minutes and seconds are 0)
__DATETIME__	Date and time when the file was compiled
__LINE__	Line number in the source code where the macro is located
__FILE__	Name of the file being compiled
__PATH__	Absolute path to the current compiled file
__FUNCTION__	Name of the function in the body of which the macro is located
__FUNCSIG__	Function signature in the body of which the macro is located. The function description with types of parameters can be useful in identification ofoverloaded functions
__MQLBUILD__, __MQL5BUILD__	Number of the compiler build

no such variable

I use this, I couldn't find any other option. You need to specify the version twice, but it's not that difficult

#property version     "23.25" // 16.04.2020
#define   version     "23.25"

[Andrei Sabitov]

Good day, dear experts.

Could you please tell me where in the code there is an error that prevents opening BUY position on the same bar with SELL that has closed the previous position?

The rules are simple (to learn):
1 Entry - slow indicator crossing 0 + fast also in the zone (buy/sell)

2 Exit - crossing by fast indicator 0

Andrey.Sabitov:

Good afternoon, esteemed experts.

Could you please tell me where in the code there is an error that prevents to open BUY position on the same bar with SELL that closed a previous position?

The rules are simple (to learn):
1 Entry - slow indicator crossing 0 + fast also in the zone (buy/sell)

2 Exit - fast indicator crossing 0 line

All works correctly: opening conditions crossing of slow indicator 0 line, only fast indicator crossed 0 line in the specified place.

A condition must be added to open a position at the specified location, slow in the same area and fast crosses the 0 line

Good day, dear experts.

Could you please advise where in the code there is an error that prevents BUY position from opening on the same bar with SELL, which has closed a previous position?

The rules are simple (to learn):

2 Exit - crossing by fast indicator 0

You are making a gross error: You ARE creating TWO INLIKERS FOR EACH TICK!

//--------------------------------------------------------------------

   DPO_fast=iCustom(NULL,0,"Examples\\DPO",dpo_fast_period);   // получаем хэндлы для быстрого
   DPO_slow=iCustom(NULL,0,"Examples\\DPO",dpo_slow_period); // получаем хэндлы для медленного

Indicator handle MUST be created once at OnInit.
