Hmmm Fair enough ... but many could have traded for the last 10 years (Post GFC 2008-2018) and not experienced a full bore market collapse/correction ... and think they are good enough only to be pants'ed. Only one good way to know if your systems/psychy can stand the test and that is experience one I reckon. I thought I was there in 2008, that is able to trade for a living having been trading full time for many years then Bang ....big reality check. My robust systems failed such a big negative event such as that as that.
BTW I see they have reinstated your HC old account ... so welcome back.
