Most prop firms operate on borrowed time. You get 60 days to hit your profit target. A handful go to 90 days at a premium price. Then it's back to square one with another fee. That model is designed for the firm's revenue, not your growth.The thing most challengers overlook: those deadlines

Let's be honest — most prop firm evaluations are a campaign against the calendar. They offer a 30 or 60 day window to pass the evaluation. Some extend to 90 if you pay extra. Then it's back to square one with another fee. That model is designed for the firm's revenue, not your development.
