Last night I placed a market buy order for Liffe Coffee, along with an attached auto stop. This morning when I logged into TWS, my order was gone but I did not have a fill. I can't find any information on this, and of course chat was unavailable. I opened a ticket and it sat untouched all day. Has this happened to anyone else? I don't care all that much about the trade (I'd be up by about $40 now -- wow!) but I'm more concerned it could happen on an exit order and I could get decimated overnight..... Edit: This was before the whole symbols in TWS fiasco today
