What you should do ? Stop looking for any trading systems. There is no consistent good one. Trade discretionary and never look back. That is based on my experience looking for good algo strategies over 10 years. It is not worth to spend your time researching, testing, etc. There is no holy grail at all. No magic indicator too.
80% failure rate is buying breakout and getting whipsawed. A guy on Reddit told me all the successful traders he knows have a negative Reward to risk. He said his Reward to risk is 1:5. He’s mad at all the “Fake Gurus” downvoting his posts.
The Holy Grail was not what I expect it to be -----> The Holy Grail did the expected. It could be cursed/jinked Better bring it to the Mount of Doom and destroy it in burning hell. 6 out of 8 success is too good (I mean too bad). Anyway, do it a thousand times and you will get 1 out of 100 success. If you achieve ~40% success rate, it means you have the real Holy Grail.
Don't like to hear the truth lol...your system is inherently flawed. Probably trading breakouts and uses support and resistance levels which don't actually exist.
