I received a PM about how I trade this system. I generate the signals about 30 minutes before the market closes. Then I take the top signals(up to 10 total positions) and put in Limit on Close (LOC) orders to enter the positions. The exit signals are traded the same way - using LOC orders.
If you want to trade this system live you can try it out free for a week getting live signals via twitter (backtesters.blogspot.com) or just follow the results here as I'll be posting the trades and exits after the close.
