Find a triangle on any stock or chart you want. When the triangle breaks find some change in your couch, car, dresser, on the street or return some empty cans and now deposit that change in an interest bearing savings account. Done. 100% win rate, guaranteed 0.2% annual return. No vague guess. Ask a stupid question, get a stupid answer.
Those patterns used to work until the algos flooded the market. Now there are booby traps where there are supposed to be breakouts, eg. head fake.
Actually not necessarily. If a trader has the right strategy for the right time, he will be profitable. That doesn't mean he is using the right tools or that he can trade any kind of market. Just that he was right for the times. If you were bullish during the Trump years or 95-99, you made out like a bandit, no matter if you used tea leaves, coin flip or TA. Now for Monday I correctly predicted the price action, both directions, using TA. THAT is proof...
The patterns still work because you can still find them. Nothing works all the time. The trick is to narrow your selection down with other criteria.
