Creating symbol for IQFeed for adjusted data

[sgordet]

I use the ##-## symbol for historical non-adjusted data that I've purchased.
I would like to separately start collecting IQFeed adjusted data.
IQFeed supplied me with the symbol format, e.g., @ES#C .
I created a new instrument in the instrument manager, gave it the ES parameters, and connected it to @ES#C for the data source in IQFEED and created a new symbol name, ESB ##-##.
I didn't receive any error messages until I tried calling it from a chart. I then received the invalid symbol error message.
Is there any way that I can create another symbol for each ticker?

Under Tools > Account Connections, there is an option "Use back adjusted data". If this is checked, then you can still use the ##-## but now it will pull the back adjusted data. Is this what you want?
