“What is the most perfect trading method?”
I am very sure that if many traders are asked this question, their answers will not be the same because the perfect trading method is different for different traders. The path to becoming a successful trader involves creating your own trading method and understanding the things to look out for. Sometimes the things to lookout for, may be what has been pointed out generally or maybe something that you personally discovered from consistently observing the charts and trading the market for a long time. One method is not perfect for every trader.
You said one good thing I agree with you because each trader does their own speed. Each trader has its own strategy by adopting that strategy and entering its trades. And if each trader is asked how your trading method will come different opinions from every trader because when a trader starts trading successfully, he verifies the markets very well and he trading from his own strategy to his own thinking. So if you want to be a radar, you need to experience slowly as the way children learn to walk. After gaining experience you will become a trader.
