Pa setups

I'm curious what, specifically, would constitute proof to you that a trader, trading a single futures contract (to ensure there's no average-down opportunity), can in fact be consistently profitable applying one or more of the following standard technical price action concepts:

1. Entering a with-trend position on a pullback

2. Entering a with-trend position on a break of a previous high/low

3. Fading the extremes of a tradeable range

4. Entering a counter-trend position based on the old 1-2-3 reversal setup
