The only way to find the best strategy is to create it, becase the best strategy for each trader is the strategy he knows everything about. Start with reading books about the markets (as much, as possible) - they`ll give you basic understanding. Then, try to watch the trading and to spot interesting idea. The next step would be to define the conditions the idea works in and to add rules. After that, back test your strategy with special software like Forex Tester or built-in TradingView tester. Back testing would help you to find out whether your strategy is profitable or not, and to make changes. If it works well, you can start demo testing. It will show you, how it would work with the impact of psycology. On this stage you will also find you whether it is comfortable for you or not.
Only after passing all these steps you should start trading with real account.
