The best strategy is a self-made strategy. You must find a good strategy customized to your preferences it means on your capital, skill, risk and your emotional reactions. A strategy which worked perfectly for a hundred people can be a fail for others. It belongs more on the way how you trade the strategy and not which strategy you choose. It's impossible or very hard to trade with the exact same strategy as another person. The problem is that every human being reacts in another way on the volatility. Beyond that everyone trades with different risk levels, Person A trade with 1000$ and is completely relaxed and Person B can't chill one minute without looking on the charts. Necessary is to learn and earn experience, with the time you will recognize which way is the best for you and then you have your best strategy.
