The activation fee is a one-time fee you pay only after you pass your evaluation, before your funded account is activated. You never pay it if you don't pass.
The amount depends on the programme and account size. You can find it in each programme's rules:
FLEX Challenge (forex): see FLEX Challenge Explained
FLEX Futures: see FLEX Futures: Activation Fees
Legacy One-Step Evaluation (futures) accounts: a one-time activation fee was also payable after passing. This programme is no longer available for purchase since 14 September 2026.
