I ask for input, as I think I have lost all math skills based on what my broker is telling me my profit is for an equity trade compared to my calulations. Bought 1000 $23.49 Bought 1000 $23.39 Bought 1000 $23.25 Sold 50 $23.56 Sold 2950 $23.40 The question is not about the trades, it is about the calculation of profit, or loss, although broker and I both seem to agree there is a profit. Broker shows a larger profit(by $350) than I do. Don't worry about commissions, but if you want use basic IB of .005 per share. Again not asking about my trading skills, just double checking if I have lost my mind, which is very possible. Thanks, and as always I promise to laugh at any abuse thrown my way, and then hunt you down and throw an equal amount of fecal matter at you.
