In order to find the one trading strategy that will bring the maximum profit, it is necessary to test many trading strategies. And even when you have found the only trading strategy that you think suits you, you should not focus on it, but continue to test new strategies.
The the popularly mentioned strategies that some traders are using these days, such as smart money concept (SMC or ICT), support and resistance, supply and demand, market structure or price action, etc. I took time to just study these strategies last year and I observe that they are also associated to one another and it will be beneficial to learn about them all, while trading, you can only use one pattern but knowing them all, helps you in some situations when the market begging to deviate, instead of still holding your position, you might close it because you already know what could happen next.
