A good trading strategy is important, but what traders need to succeed is not an absolute strategy that gives 100% winning. A 60% winning strategy is okay if you can work on your trading psychology and money/risk management. As simple as the two are, they've reshaped my trading results for good.
A 60% is an exceptional trading strategy provided the risk to reward ration is atleast 1:3. What you need as a trader is a trading strategy that is at least 50% win rate for a 1:3 risk to reward to see your equity curve move exponentially. One important thing about trading is also the fact that trading is mostly psychology and little of strategy because most of the strategies work but their application is what makes the difference.
Armed with sound trading psychology and a good trading strategy, a trader is bound to succeed.
