Hi,Pivot point times based upon the symbol's RTH . Because the contract names change periodically I am trying to use wildcards after the first two letters of the symbols so I don't have to update the code every month.Wildcard string compare (globbing) - CodeProject , but I am getting errors within the function that I don't how to resolve.

Hi,
I have about 10 instruments that I follow and I would like to have certain default input parameters for several studies automatically change depending on the instrument I currently have selected. For example, change
Pivot point times based upon the symbol's
RTH . Because the
contract names change periodically I am trying to use wildcards after the first two letters of the symbols so I don't have to update the code every month.
I found a wildcard function here
Wildcard string compare (globbing) - CodeProject , but I am getting errors within the function that I don't how to resolve.
Any help would be appreciated. Thank you.
