Eric, The point is Alphe already backtested a 100% mechanical system, and gave us blow-by-blow commentary on his siulated trading, to the tune of >1000 posts. We all warned him about the challenges of real trading (not simulated) with real money on the line, both psychological and from a systems trading perspective. That's why we're on his case now. He didn't trade his plan. I wish Alphe would trade his plan. I'd like to see the results of that very short-term system, backtested with slippage & commissions factored in on real-time simulation.
