Was trading ER2 on HK server. I submitted a limit order, which apparently never reached the market. It never executed. I tried to cancel the limit through the API. No go, so I tried to bring up ER2 in TWS. When I look at Futures, every monh is listed for the next several years. Anyway, the symbol was finally added and I flattened. Now the weird part. Executions only shows 1 trade for the day, even though there were four. Crazy.
It is not a good idea to trade ER2 on HK server. Some of HK servers are restarted about this time. You could also have a bigger lag. I would recommend switch to US.
