Being successful in this game is having good trading ideas, being competent enough to code them, backtest them properly, and then put them into production. If one of my clients said they wanted to identify candles with a large price move, take a bitmap of the previous 20 candles and feed it into an image classifier, I would say that was a reasonable idea to explore. This is a very simplistic example to illustrate a point:- for scenarios like this, I would say it is the Neural Network that is identifying price action and not the human.
