The closest you can get to would be Water House Capital. The datafeed is as close as you can get to the market exchanges. Commission is a bit hefty on futures, indices, etc.. But if you have a good trading method, you may be able to handle it. Otherwise, get the demo for charting and trade with one of the regular US brokers to save some commission. Depending on your trade volume, you can save more commission if you get one of them exchange seats.

Concurrent with WHC charting, I also use Ninja Trader for their charting and order management with no platform fee. In due fairness to WHC, at least open a live account to trade their forex spot.
