I think gainer may have just shifted from a commission-free broker (a LOT of accounts are set up this way) to a broker that charges commission. This lead to a whole extra column in the report to take into account. That would be a very confusing situation at first.
Now that he's spotted it, life should be a little easier - at least until Triple-swap Wednesdays. If you don't know about that, it can be a very big surprise the first time it happens.
Thanks alot for answering this question the way you did, I was already imagining of big possible answers. Your answer is so professional! Thank youWhen you had the $11.13, were any trades open? If so, the floating P/L would have changed your equity and it would have kept changing every time price on any open trade went up or down.
If you had $11.13 with no trades open, then opened your 10 trades, paid no commissions or swaps, and then closed all 10 trades wit $1.86 in profit, your new balance should be $12.99.
Post an account statement and that will make it simple to see if the numbers aren't adding up correctly.
