Hi Free - Yes, I thought that shorting QID was a clever idea for improving your fill. Re short interest, my guess would be that IB would still charge you a higher rate to borrow the stock than they would credit you on the proceeds. Still, I haven't seen any other brokers that are willing to credit you anything at all, so I thought that was pretty neat. I have never used IB so I hope I understood their policy correctly. I suppose you could call them and get the scoop ( after talking with at least 3 reps of course 8-) I am mostly with the fund companies now, but I have used Datek, Ameritrade and Scottrade in the past. I tend to like the flat fees, and they are low enough now so as to be pretty negligable.
