Why does the compiler give the implicit enum conversion warning ?

long type = PositionGetInteger(POSITION_TYPE);

ENUM_POSITION_TYPE type = (ENUM_POSITION_TYPE)PositionGetInteger(POSITION_TYPE);

Thank you, brothers, you're a lifesaver.

Because PositionGetInteger(POSITION_TYPE); returns value of long type and must be converted to enum type.

In the script.

This works correctly. Selects indexes without repeating values from the array to be checked.

can't find how in the code for the print, to insert the version number from #property version"1.07", no such option? the program name is there, why isn't the version there as well?

Fast235 #property version"1.07", no such possibility? program name is there, why version is not there as well?

No. And no matter how many times I asked about it, the answer was always the same: silence. ;)

[Maxim Kuznetsov]

Fast235 #property version"1.07", no such option? the program name is there, why isn't the version there?

like this:

#property copyright "Maxim A.Kuznetsov"
#property link      "https://www.luxtrade.tk"
#property version   "1.00"

#define  VERSION "1.023"
#property version VERSION
void OnStart()
{
   PrintFormat("Version %s",VERSION);
}
