every Trading Strategy that can tell and bring you the Right Decision to make a Profit is the best. we know that each trading system can use a different approach, I personally use Mathematics and Statistics to Analyze the Market. many people use Supply Requests, resistance support, Classic Trading, Candle Sticks and others, it just uses a different approach and different Trade Rules for sure and a good strategy is a strategy that fits your character in a great trade and not according to other traders, because you might be able to get some big profits if you match the strategy you are running, and don't trust your tutors too much, because when trading, you are responsible for yourself, not your tutors who teach you about forex trading
