I will keep this short and simple--and this post is to open our trading understanding a little.
As the title reads, oh yes, it's true, but they still lose.

They are busy chasing a better strategy that can only exist in their imaginations, thereby losing focus, and then style drifting.
Those simple strategies you undermine are enough for you if you work on yourself. I was shocked when I realised someone bought a trading strategy for $3,700...oh my God!

And guess what, it failed him, what a waste!
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.
Reshuffle that mindset and see the result in months.
