Quote from MKTrader:
That's the bottom line.
You can always find setups that appear to work in hindsight with Wolfe, "Reversal Dynamics," Gann/Elliot stuff, etc. However, I've never seen anyone design 100% mechanical rules (or better yet, just automate them in a trading platform) and prove their worth.
The marketers usually say "it's a great tool but you must add other patterns, indicators, your own discretion, whatever" for buy/sell entries. In other words, there's no evidence that they're profitable. You could probably draw stick figures on your chart and "predict" future highs/lows with as much accuracy.
