Where was your stop!

[Orpexo]

I think it’s tough to put a pin in any fixed amount an individual trader should risk.
It really boils down to their own style, and specific appetite and long-term goals.

If you want to put 20% of your equity up on a single trade, by all means go ahead (I wouldn’t advocate this though).
No one is going to stop you, and, if you’re accurate enough over time you can rake in some serious returns.

Isn’t that like telling people they can drive over the speed limit if they want? Sure the chance of having an accident or a fine is pretty small, but it is still a bad advice.
