No I can't. But does one have to be perfect as the example mentioned in the first post operates on a 50% win rate?
There would be no need for perfection. A mechanical system that takes profit at a predefined short term target eg 2R, would be able to be executed with a buy stops, stop loss and profit target order all entered together before the trade has executed.
Even slippage can be negated with a buy stop. Of course the stop loss may prove a different matter from time to time.
At this point I'm not sure what we're discussing.
A 50 % win rate system targeting 2R have a positive expectancy at 0.5R pre-comission. Nothing wrong with that if you can sustain that performance, but not very robust.
A fixed mechanical system will not generate more profits than an adaptive system which aims to capture the bulk of each major move, though. But a fixed mechanical system is probably easier to create for the average retail trader. Probably easier to go for 1.5R and a higher win rate.
