Quote from Option Trader:
This also cost me as much as $3k of profit as well. This happened to me before the 6 business days they require for funds for a deposit to clear. Did you also have a special situation like that?
My funds were clear as I had the account for a year and was trading only a small portion.
I don't recall exactly but the changes from my limit sell prices were around 7%, which took the trades from clear winners to losing.
I was up quite a bit but the finagling was such a blow that I've not traded for two weeks and am still looking for 2 new brokers to use,
who are fast and reliable, perhaps TOS and IB but I need to learn more about them before trading again.
