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!
Should I say this is greed or what? Because I have never seen something like that before. Real traders don’t do that. This person doesn’t want to learn; he’s looking for a shortcut to earn money from trading, and that is why he feels buying a strategy to trade will make it easy for him.
Blame this person less, my friend, it's not the first time people buy custom indicators and services. Some work, while others fail. And if it failed him, it doesn't mean that the strategy bought is totally useless, the buyer may not know how to use it correctly, or is not managing his account well, or he is emotional altogether.
And one thing about these expensive products is that they're targeted at a select few, the rich. It's not meant for regular people, and they don't mind selling only 50 pieces. So, consider the buyer rich, and I won't blame him for trying.
