I've been having this issue all month. I use bracket order to trade futures on NYMEX. And for some reason whenever I get filled on my opening order, my profit target limit order does not work. I see the order status as light blue and sometimes pale purple in TWS. Stop orders seem to work fine. Has anyone had this problem? I contacted IB two weeks ago and sent them the screenshots and I still haven't heard back from them. I keep seeing light blue and pale purple order status colors. According to IB......."LIGHT BLUE indicates that you have transmitted your order, but have not yet received confirmation that it has been accepted by the order destination. PALE PURPLE indicates that an order has been accepted by the system (simulated orders) or an exchange (native orders) but that currently the order is not working, due to system, exchange or other issues. When the order becomes active, the order status color will change appropriately."
