Stick to your exact same strategy that got you funded. Don't increase lot sizes. Don't change your trading plan. Treat the funded account exactly like you treated the evaluation. Also, consistency beats aggression. Many traders blow funded accounts because they chase big moves instead of following their proven system.
I think the hardest part is resisting the urge to "maximize" the opportunity. Many traders pass an evaluation with disciplined risk management, then double their position size because they finally have access to larger capital. That's often when the problems start. The goal shouldn't be to make a month's profit in a week. It should be to survive long enough to collect consistent payouts. Slow and steady may sound boring, but that's what keeps funded traders in the game.
The biggest challenge after getting funded is managing the psychological shift. During the evaluation, you're focused on passing. Once funded, you're suddenly thinking about payouts, account scaling, and protecting the account. That pressure causes many traders to either become too aggressive or too cautious. The traders who keep their accounts are usually the ones who treat a funded account as just another trading account and stick to the same process that got them there.
Discipline and fomo, that urge of wanting to receive a payout
