fair caution, a rebate on unprofitable volume just loses money slightly slower. but assuming the strategy is genuinely profitable, lowering cost per trade is pure edge improvement and absolutely worth pursuing. the discipline is to confirm the volume is profitable before costs first, then negotiate the costs down second. do both in that order and the rebate is real money, not a consolation prize.

name the constraint it solves or stay retail ecn.

added a spread filter blocking my rollover entries and my random unexplained bad fills basically vanished cant believe i white-knuckled through that window for so long instead of just gating it.

get a competing quote in writing first. then email your account manager with volume history attached. works.

to make it concrete for anyone trying it: set both legs identical at entry, log them as separate trades, and use server-side stops on each so a platform issue on one doesnt orphan it. the moment you find yourself mentally tracking them as one position is the moment a mistake is coming. independence on paper and on the server, not just in intention.

ecn broker, raw account. position size becomes the execution variable not account size.

run parallel. full switch only after 3-4 weeks of actual execution data on the new one.

100-250k equity minimum is the practical floor. below that a good ecn is effectively equivalent.

it's fine. just watch dormancy fees and verify margin calculation is per-account.

fill quality and withdrawal depth over headline spread. agreed.
