Hi, Last friday, I submited a MOC order on AMLN at 10 AM for 126 shares and 5 others MOC on differents stocks. All the day, I saw it on the Pending page and Portfolio page in the TWS. Few seconds after 4:00 PM, my MOC order on AMLN was cancelled... and the 5 others were filled. The Volume at the close was big for AMLN, so I don't understand why this MOC order was cancelled. It's not the first time that's happened! So, is there a problem with IB, TWS, NAsdaq? Was my order really submitted by IB?
