Quote from RichardRimes:
Neke I know you take comission costs into consideration in showing net gain but have you totaled the cost of comission and compared what you are paying with what it would cost at IB?
Took the opportunity to analyse my commissions. Since the start of the year, paid $14971 in commission. That was 5422 option contracts total(entry+exit) for 9091 commission and 782600 shares (entry+exit) for 5879.
Given that a typical stock trade might be 700 shares @ 40. For Ameritrade, the cost is $7, while at IB (at $0.005/share) it is $3.50. For option a typical trade would be 10 contracts. The cost at Ameritrade is $13.5 (7+0.65*10), while for IB it would be $7 ($0.70/c). So yes, all in all, I would probably be saving close to 50% at IB at this time. When I had much higher balance on my account and trading bigger sizes, the difference wasn't there. I have built my platform so much on how Ameritrade works, I am not ready to do a rework for IB at this time. But thanks for pointing out the commission. It would certainly have made for better returns. Who knows how much went to slippage. Those are big barriers to profitability in short-term trading, and why I am keen to avoid intra-day noise trading, but only focus on plan developed before the market opens.
