Quote from OptionsWizard:
I also keep accounts with IB and TS. I have 95% of my trading activity with IB and use TS mainly for charting and strategy. I trade with TS just enough to avoid fees.
TS is a great platform for charting (the best, IMHO), but they have a lot to learn as brokers. IB is a better broker in almost any category.
Better quotes (TS lags behind IB), faster execution (just an impression), more markets, better margin rules (see my previous post on this issue) and yes...even better customer service.
