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!
That’s just plain greed.
Yes, there are strategies that can make you profitable in trading, but you don’t need to pay for them. There’s no shortcut to building real skills.
The information and data are free, we just need to use those tools to improve ourselves. Eventually, by learning from our mistakes, we’ll get better.
If it were up to me, I’d rather use that money as trading capital than waste it on some so-called “strategy.”
