Saturday to evaluate the trading results this week, reopen the wrong open position record, looking for a reason why my analysis could be wrong, so it won't be repeated in the future.
Sunday for market analysis next week, looking for those who can potentially generate profits, as well as noting the News one week ahead.
Of course this answer is very stifling for me, considering that traders' habits are Friday's time for WD, Saturday and Sunday vacation time, but I'm not at that point yet, I'm still learning and developing hopefully hopefully at that level.
