I mean who is going to give up TWS to trade off a web page ???
They say they are going to make it easy to switch from 'pro' to lite, but theres no comparison for any active trader.
If they want to compete properly, they need to allow trading off the TWS (and API) , where the trade gets routed to payment for order flow houses if thats what you want for the free trade
I personally could care less where the trade gets filled, as long as I'm executed at the current price. Smart routing is no bargain , you get frontrun and pennied anyway
