I've been trading options on IBKR for almost a year now. I have always been able to get rebates for placing limit orders on many different underlyings, such as W, WORK, LUV, and CHWY.
Suddenly I cannot get rebates anymore! My commissions are always positive.
Does anyone know what is going on?
Make sure the "Sweep to Fill" field on the Order Ticket is unchecked and make sure "Post-Only" field is checked off so this way your order is guaranteed to be a passive liquidity-adding order sitting on the exchange to be hit by someone else. And I always sent orders to specific exchanges that pay the highest rebates for liquid-adding orders instead of using "SMART". With "SMART" order routing, you really have no control over where they send your orders. I had some success earning rebates with this arrangement until IB decided not to send my orders to the exchanges right away when they were supposed to and instead held them in their internal server and only sent them out at the last minute when my limit price was reached and thus turning my passive liquidity-adding orders into liquidity-taking orders thus denying my rebates. And all of sudden, I would be hit with massive positive commissions.
I complained to IB several times about this and their excuses were always because they were trying to do better price matching for me, the price moved and blah blah blah bull**** like that. I dunno if that's what is happening with your orders but certainly talk to IB to see what they say.
