agree with this terms. how many return will come by trading strategy it depends on your trading risk management.
I would say there is no best strategy when it comes to Forex as the market is highly volatile. But you can strategize well with risk management, and technical charting analysis and can use Stop loss to limit your risks.
There are multiple trading strategies and it's possible that the strategy that works best for me won't work for another trader. So, it's best to experiment with different strategies until you find one that works for you.
I don’t believe in settling with one strategy when even the market can’t settle in one position. Different strategies may work in different market situations. So, better experiment with various strategies and stick to them when you are already in a trade.
the success of your trading strategy depends on your money management , otherwise no way to survive successfully.
