Here's an example of a bar-by-bar analysis in which I take a trade immediately upon close of a valid signal bar, with initial stops left in place, never moved to break even:
Sh @ 76.44, sl @ 76.50, pt @ 76.14: pt filled for +$300
Sh @ 76.27, sl @ 76.42, pt @ 76.99: pt filled for +$280 (if able to move pt, then more)
Lg @ 75.72, sl @ 75.63, pt @ 75.94: pt filled for + $220
Sh @ 75.75, sl @ 75.95, pt @ 75.46: pt filled for +$290
Lg @ 75.42, sl @ 75.30, pt @ 75.78: pt filled for +$360 (if able to move pt, then more)
Sh @ 75.79, sl @ 75.87, pt @ 75.55: pt filled for +$240
Sh @ 75.60, sl @ 75.70, pt @ 75.40: stopped out for -$100
Sh @ 75.67, sl @ 75.81, pt @ 75.49: pt filled for +$180
Lg @ 75.35, sl @ 75.24, pt @ 75.58: pt filled for +$230

) I'd say it's fair to assume that you could probably trade safely with 2-5 cars. If you backtest your strategy (not just for a few selected days and, as I'm sure you already know, including commissions and realistic slippage) and you actually have an edge half that good with a drawdown that you find reasonably easy to stomach, why not simply trade it mechanically?
