FAST, CLASSIC, STRIKE & INSTANT explained:
The names actually tell you how many phases you need to complete before reaching your Master Account.
FAST is a one-phase challenge. One profit target, then you're done. It's the fastest path to funding through evaluation — hence the name.
CLASSIC is a two-phase challenge. You hit the first target, then complete a shorter second phase before moving to your Master Account. It's the more traditional prop firm structure, which is why we call it Classic.
STRIKE is a three-phase challenge. Three targets to hit, each one lower than what you'd find on the other accounts. It takes longer, but the entry cost is the lowest of any challenge account — it's designed for traders who want to pay less upfront and are happy to take more steps to get there.
INSTANT is zero phases. No evaluation at all — you go straight to a Master Account from the moment you purchase. No profit target to hit, no phases to pass. You're trading on a funded account immediately.
