a Forex Story

Here is a story about myself. I am a careful person, I believe that if we cannot make money when we backtest, then we will not able to make money in the live market. with this mindset, I started to learn trading strategy and test them before I put my money in to the market. But I death in a loop:When I learn a new strategy, it's work for a period,after that it will start some problems, for example, there is no setup in a week, or almost setup was fail and I have a steak lossing. then, I try adjust this strategy, and you know that, it become worse than before.Finaly I abandon that and try newone.By this way, I tried a lot of strategy from phantomtrading, fragtal market, flipping market,... etc.And a deepest sistuation is that I cannot see, action, or even thinking about any things. Even if a setup was work in a specific time, I try it in this specific time and specific setup again. But I CAN'T.I realize that, I cannot doing. My brain is just stop working.Myself has overloaded and they have to release. I browse on some website and I see a review about a book "How I made 20000000$ in stock market" of Micolas Darvas. Oh, that book, I was heared about it before, but the author is not famos too much, the book's name is smell selfhelp and it about stock not forex. And the reviewer also feel like me but he changed his mind after reading this book. And you know I also changed my mind after reading the first page.And when close the book, I am starting with basic question, what is a strategy? It's just a set of specific criteria. And Darvas strategy is only 2 criteria: specific moving price and volume increasing and he success.I look back to the strategy that I tried before, it has almost 5 to 10 criteria.And I am a new person. How I can keep myself to follow this too too much criteria like that in the long term, right?My mind was realeased.Now, I only use 2 criterias (HTF struct and entry model) and play with them again every day. The good things is still a blur picture. But a clean and peace mind was appear.
