Hi, apologize if this is something stupid.
But I been running a new algo on NYMEX GC on Aug contract exp 2019-08-28 for past fews weeks.
Tonight I was hit with being BUY order being rejected due to Interactive Brokers phys delivery rule that cuts off any long order for this contract on 7/30th!
I was like OK, I go next contract with exp 2019-09-26.
But this contract is hardly liquid. Impossible to trade.
Do all brokers have this rule? If so, how are you supposed to trade GC now to get normal volume? Or is this just IB rule?
