Invalid issue in UpdatePrices

Hedge Nasdaq 100 3x Short (SQQQ) does not work.
“Invalid issue in UpdatePrices” is returned.

Hi Georg. SQQQ doesn’t have data before 2/11/2010. So it can only be used as a hedge if the sims start date is >= that date. (Actually a date as early as 2/5/10 works)
I’ll create a ticket to get a a message that is more clear then “invalid issue in UpdatePrices”.
