I've been having a weird issue after hours trading ES futures ( E-mini ). Whenever I have an opened position, I like to set a contrary ( protective ) Stop Limit Order pretty far of the market, just a protection against dangerous issues as Internet service/Electricity down fir example. But when this protective Order is submitted in IB, the order is immediately canceled. I asked them and they say there are a maximum limit for prices set by CME ( Globex ) but they didn't say it. Any ideas?
