after 10+ years of trading hundreds of positions each and every day,having endless list of observations,backed with stats and backtesting,comparing my real results with a paper etc you are telling me that those regulations(that created sub penny,hft,order internalization etc) have nothing to do with my trading? stat correlations is one thing,but if you can't get any shares on winning trade no matter how hard you try to get in... from 82 % fill ratio all the way down to <20% now(keep in mind-losers are always filled in full)..i rest my case..good bye
Go to market......filled......end of story. Go cry me a river. Oh wait, I forgot, your margins are a fraction of a penny so if some HFT shaves off a fifth of copper, your businesses is rendered useless. Nice dude. I think regulations are the least of your worries. I'm more worried about you cutting your ear off.
