Throughout my short trading career I've not paid much attention to the routing of my trades until now. My new broker has a long list of routes, which I'm allowed to select. I'm taking liquidity on 90% of my trades. I trade NASDAQ stocks with a lot of liquidity and momentum. I place my limit orders in 500 share increments. Which would be the some of the best routes for my orders to get filled at the best bid and ask prices? Thanks
