There is no fixed deadline to complete the 1-Step Challenge evaluation. You move to a Funded Account as soon as you hit the profit target, complete 3 Minimum Profitable Days ( at least 0.25% profit each day) , and follow all trading rules, then request progression through your Dashboard. How long that takes is entirely up to your own trading pace.
Instant Accounts skip the evaluation altogether. You are funded from day one, right after your purchase and KYC are complete.
