nice trading.
here's a tip for ya. if you go through a prop firm you can get the full ECN rebates. So you can choose the best order route. BATS is a popular route. Here are the rebates

if you can come in and out on a limit order you can capture $0.0029 per side from BATS, even more if you can go with Sigma or other dark pools, you can catch $0.005 per side. A prop will charge you $0.003 to $0.005 per trade depending on your volume, so you can potentially trade 'for free' by letting these rebates offset. In addition you are not limited to the 4 times leverage imposed to retail traders. so if you stump up $50,000 on an IB retail account you can leverage up to $200,000 intraday. Props will normally give you 20 times buying power so if you deposit $10,000 you could trade your $200,000 intraday. there are plenty of respectable prop firms out there.
