FWIW, I closed out a rollover IRA I was trading actively at Fido three years ago because the connectivity was poor, the fills were slow and the slippage was terrible. Why anybody would use Fido is beyond me when there are so many other web brokers out there. Even Datek (now Ameritrade) was better. Best is IB. Near instantaneous fills, acceptable slippage, rare connectivity problems, no bookkeeping screwups. Just my opinion, earned the hard way by getting screwed and wising up.
