Are you sure that the version you are running is the version you have shown here?
This would be a serious issue
Print("OrderSymbol ",OrderSymbol()," OrderTicket ",OrderTicket()," OrderOpenPrice ",OrderOpenPrice());
Isn't it showing the same info as this one?
Yes, I'm sure
Problem solved. In the logic block there was a user function operating with another OrderSelect that was the reason of sending last selected order data outside of the function to program environment.
UPD.: MetaQuotes support also suggested to:
make the variable "magic" different on all the charts for each advisors.
