I've been working on a strategy that essentially briefly spams post only orders around the spread to get more fills. Rebates can be highly lucrative in crypto compared to legacy. What I don't understand perhaps is the way they give priority to people in line in the que, as in whether I get my order filled before people who placed orders *after* me , at the same order. I've wondered if bybit or mex engage in any funny business about giving certain people priority status in line, as in they always stay at the front of the line and get the maker order filled and retail noobs get pushed to the back.

I've had some astonishingly good results on derbit testnet gettng rebate orders filled with my technique, but the liquidty in the market dried up and the testnet broke again and now im lookign at the bybit testnet and it is just terrible too, even more terrible. It will fill every order but mine and my test order of 300 contracts just sits there holding up the spread. It really doesn't make any sense.

I would love to hear from traders on how easily they get their maker orders filled on any of these exchanges. 15% round trip s far far too high a fee, and the rebates are far more lucrative than i ever believed theeyd be, often doubling my profits.which should give you an idea as to how devestating even casino like these fees are. Fees in all of crypto, coinbase and cashapp included are absolutely criminal.
