I use U.S etrade, so I don't think so. I haven't had any issues with them.
I will change brokers though - will explore the route of trading through a set-up company through IB.
If I can get margin under that structure, I will be 100% switching. In the new year, because of the frequency I've been trading in & out of my positions, commissions is currently sitting at 20% of my profits. I need IB commission levels to bring this down to <5%.
At end of day, it depends on your strategy and your requirement as a trader.
