Yes! In the Oxford Challenge, each phase requires you to trade a minimum of 5 distinct trades on separate days. So, if you hit your 8% profit objective earlier than 5 days, you will still need to trade the additional days to meet the 5 trading days minimum in each phase.
If you successfully achieve the 8% profit objective in Phase 1 of your challenge in the 5 days and follow all the rules, you will move on to Phase 2. If you need more time, this is okay since we do not impose a time limit.
The same goes for Phase 2. If you hit the 5% profit objective in a minimum of 5 days and stick to the rules, you will qualify for a Funded Prop BX account.
