I wanted to share a very simple cost analysis that I do every year regarding my trading activities. As an "active" trader, I really have to take the costs into consideration. Market data and platform fees per month: Tradestation Platform, Tradestation Portfolio Maestro and Tradestation RadarScreen: Free Prof. Market Data: $190 (indices, Globex, Amex+Nasdaq+NYSE real time) TWS (Interactive Brokers) platform: Free Prof. Market Data: $124.25 (Stock & option streaming) Mluticharts: Free (lifetime licence) Yearly commission on trading: Futures: $1,578 (Tradestation) 300 lots Overnight fees $135 (Tradestation) Stocks: $6,412 (IB) 584,652 shares Options: $13,580 (IB) Just simple calls and puts. 9972 option contracts Interests (IB broker paid): $680 (I use high leverage for stocks) Good: Low commission on stocks & very low interest rate Free platforms. Less good: Commission on futures (not the best but free platforms), professional market data fees which are unavoidable. Bad: Overnight fees, no big deal but probably avoidable. Options: Even at $1.36 per contract, need to lower the costs. I just found eoption. The option commissions are actually amazingly low. After doing the maths, I should pay: 1092 order X $3 (commission 1) + 9972 option contracts X $0.17 (commission 2) = $4,971. If I go with them for option trading only, I will have won $8,609 more, next year just with this move! Anyway, I just wanted to share this annual review of my costs of trading. Anybody actually know or even trade with eOption? I still need to do some research before I open an account with them. Good trades!
