Rule 1:-
This is the internet, you don't know anyone really, assume everything is a lie, cause everybody lies, get over it and move on.
Rule 2:-
When someone is possibly honest, don't discourage it, by calling them a liar.
Too many variables, here is a quick list of possibilitys!
1. He's Rich already, just trades his retirement funds tax free cause he's tight.
2. He blew his regular account and only has 401K's left
3. He has a job which pays him enough, so he's trading to boost his retirement.
Read back, he clearly said he sucked for ages, then he had a good run where ES behaved to his method, that period was the ATM period, it'll go back to hard work again soon.
Trading is never easy, will never be easy, 99% of us aren't trading with large amounts ( me for sure ), get over it!!
