Quote from hajimow:
That should be the case but I guess since BOX is not that active as CBOE or NASDAQ. So when you remove liquidity, don't expect to get rebate. Leave it to the hands of luck. Basically when you set your account to highest rebate, it does not mean that your orders will go to lala land and will wait for a buyer or seller so you get the rebate. Speed and execution is also priority from your brokerage side.
BOX is very active. 99% of IB options orders are routed using IB's SMART Routing system. And the majority of the non-directed market orders go to BOX, not NASDAQ or even CBOE.
This may be explained by the fact that the Timber Hill subsidiary of IBG pays the IB brokerage subsidiary $1.00 per contract for each order routed from IB and executed against Timber Hill via BOX subject to some stipulations outlined here:

So there is a significant payment-for-order-flow incentive for IB to route market orders to BOX or whichever other exchange is designated by Timber Hill.
Still, the BOX rebates for taking liquidity are substantial and it's great that you are able to receive those as pass-through credits using the "highest rebate" function you have described in this thread.
Are there any other exchanges that pay rebates for taking liquidity, or is this unique to BOX?
