For 2-stage challenges, there is no minimum or maximum number of trading days (there is only a minimum number of profitable days). You can reach the profit target in a single day or in a year. The key is to avoid inactivity: a trading account that is inactive for 30 days is automatically blocked.
For a 1-stage challenge, the minimum is 6 trading days. This gives our risk managers enough data to assess you as a successful and consistent trader.
Activation deadline: After purchasing a challenge, you have 30 calendar days to open your first trade. If you do not open any trades within 30 days of purchase, the challenge is annulled. After activation, a separate inactivity rule applies: at least one trade every 30 calendar days.
For Instant accounts, the minimum is 10 trading days. There is no maximum number of trading days for Instant accounts.
