The market maker pays for a seat and in return their bid/ask gets priority over a customer bid/ask when retail orders come in.
This is backwards. Customer go in front of firms.

In short, the title says what I'm up to.
I saw a recent discussion here stating this is a bad idea ("You just can't build a model that works as non-member to compete in equity options." - Robert Morse), but at the same time another member says this might be a great opportunity ("The options industry is going through a new evolutionary period in the liquidity equation. Many of the midsize firms have left and the very large and the smaller MM's are pretty much the survivors. If you want to really make markets I would spend the time looking at what it would take to mount the effort. If another major chooses to exit - the vacuum created could offer a major opportunity." - ajacobson).
My reasoning is that if I'm able to do arbitrage through Interactive Brokers latencies then I know enough to also be able to do market making. Like, I know what I'm looking for in making money off others, then at least they won't be able to make money off me in the context of my models and strategies. Stuff works wonderfully in backtests but the major question is: "will I get executions on join orders?". And the only way to find out is to implement a market-making system which is able to manage at least hundreds if not thousands of quotes.
In the meantime of course, I can always polish my arbitrage and research new ideas (got more lined up than time to work on them).
Anyone else here who's doing market making?
I'll pick a slow product and cut my teeth on that - as I said earlier forget about SPY,BAC and APPL - that market is well served by the existing community.
Do market maker often "run over" each other? When the spread moves, does one market makers bid hit a slower MM's ask and fill, or is there some mechanism in place to prevent this?
And, do market makers try to maintain a certain target amount of shares? I.e. Use a penny spread if balanced, and a two penny spread favoring the move towards towards balance (outside the spread on the ask if under target, on the bid if above)?
