A good trading strategy is important, but what traders need to succeed is not an absolute strategy that gives 100% winning or close. 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.
Exactly success can be gotten when all of this factors are considered and put into action,but I wonder why one will spend so much on a strategy that tends not to deliver results.And one thing about trading that I understand this few periods is that,you don't have to do too much when you got a good strategy but being able to manage all of the resources matters in giving you a profound results, which includes risks management as you've mentioned and the rest of them.
