Anyone noticed similar problems on HKFE with IB? This is not the first time. Trail is something like: 14:49:42 Deactivate SELL STOP aux. 29774 14:49:42 Acknowledged by exchange to SELL 1 contract HSI 14:49:45 SELL 1 contract HSI at 29763 --------------- The first time I called IB customer service and the staff said the order was sent several times. The second time I called, the staff told me the order was submitted only once and HKFE responded with a delay more than 2 seconds. Since there's no MARKET order on HKFE, a LIMIT SELL at 28880 (which is 29774 * 0.97) was sent. But the price was 29771 at 14:49:42/43, why the order was not executed the first time available on HKFE?
