Maybe Im just dense, but I could never wrap my head around this constant harping on the 'broker trading against you'.
If you believe that there are profitable algorithmic strategies that target and trade against retail order flow, then it's natural to understand there's some paranoia around how brokers get your trade executed. Not saying that they are necessarily trading against you themselves, but many brokers sell their order flow to outside entities, or perhaps route your order in a way that allows information leakage. Whether or not you care might depend on your trading strategy though.
