You may find that there are many forex trading strategies out there and struggle about which one is the best to use. The answer is: There Is None! 
What I mean by that? Well, the best strategy for each trader is not the same. Some traders trade with one particular strategy and earn thousands but the same strategy may not be as effective as the former traders.
The best strategy is the one that you are familiar with and with good money management. So, if you don’t have any strategies yet at this moment, go and look for some and sort them out to 2 or 3 strategies. Then, set some time to test it out in demo account and choose the best for yourself.
But one thing you must remember: There’s no never-loss strategy. Forex Trading is a business. In a business, you will face losses but if you have a good money management and discipline, you are on the right track to profit more than loses.
An effective and profitable forex trading strategy is very much depends on the time period you trade and the money management(stop loss or trailing stop). Therefore, it’s good to demo trade in the same period of time to find out which time period is the best for that strategy.
As well, you need to know what trader are you. Are you a day trader? Or a long-term trader? Or a swing trader? Determine which trader are you will help you to identify what time to trade and how much you are willing to risk.
Go ahead and explore the strategy you learn now. Take one or two months to test it out to see if it is good enough.
Happy Forex Trading with your Best Forex Strategy!
