Is this a NYSE listing rule, or just the broker policy ?
I can name three that will not let you post orders out 30% from the last trade. I don't like that limitation because I have had some stocks I own go up very fast and fall quickly. If they don't let me put my orders out (HFTS Malfunction Insurance) its time to move on! Its not the NYSE or other Exchange Rules, the Brokerages are just being silly!
IB has a dynamic "feature" that's so restrictive it sometimes won't even let you hit the bid/ask or put in a market order to close an existing position if their algorithm in its wisdom decides the spread is too wide. Try some out month corn futures orders on the paper trade account to test it out.Can you share which ones ?
