Okay, I am making some good progress. I use the following line to extract a portion of the ATC name
MidSym = StrMid(Symbol, 1, 2); I have it offset by 1 character to remove the ~ (tilde?). Now I am stumped in that I can't figure out how to use the WriteIf function: MSymbol = WriteIf( MidSym="GM", "^GSPC", "^NDX"); I get an error here .....................^ something about incorrect type MSymbol will be a variable that contains my market index symbol based on which ATC code I have currently selected. if ATC name is ~NDX005MA my MidSym returns ND and I want MSymbol to be assigned ^NDX so it will plot the Nasdaq 100 Index. Likewise if MidSym is GM then plot ^GSPC (SP500) and if MidSym is RU then plot ^RUT (Russell 2000) etc. So if some kind soul can give me a hint as how to perform string comparison and an if-then coding I would be grateful.
