My question is:
Is there any way to receive alerts when this trade setup occurs on any cryptocurrency or forex pair, etc (is a very specific setup, I dont think is a normal macd crossover etc... ..
I believe that you make your own custom alert in TradingView, but you need to learn their scripting language called Pine Script. You probably could also find basic guides and other educational materials in YouTube and the internet in general.
Plus what are the rules to EXIT the trade? You could back-test the strategy when you have both entry and exit. Compare that strategy against a simple Buy and HODL strategy with the same time frame, and see if the "professional trader's" strategy could outperform.
