Actually you might also stay with ib because: - range of markets - technology and 3rd party tools - data supplied - quality and speed of executions as well as low cost. Customer service, especially hand holding is never likely to be their big thing but I note that responses on their bulletin boards have just taken a big jump ... huge improvement.
The P&L and realized P&L are wrongly calculated. Scenario: Trading SGXNK. Sell 2 at 16730. Buy 1 at 16750. Numbers shown in TWS main window once I completed the trade: P&L = -20000 [wrong] Realized P&L = -20 [wrong] Unrealized P&L = -10300 [correct] The correct numbers should be: P&L = -20300 Realized P&L = -10300 Unrealized P&L = -10300 Realized P&L is ridiculously calculated as -20. I get no clue what bug causes such a huge miscalculation. They should be fixed as soon as possible.
