Fees

Effective as of Jun 2026 · source

Makers pay 0%. Takers pay a topic-rate against a symmetric parabolic curve: fee per share = rate × price × (1 − price). Peak at 50¢. Three discount layers stack multiplicatively (user-tier × per-transaction × referral), but a $0.25 floor per trade always applies.

* Taker fee scales with contract price (fee per share = rate × price × (1 − price)). Peak at 50¢, zero at the extremes — open to see the curve.

Fee floor

$0.25 per trade

What's distinctive: Discount layers stack multiplicatively, so effective rate depends on user tier, the per-transaction incentive, and any referral bonus. Compare with the $0.25 floor in mind — small trades may hit the floor before the curve.

Specific operator-entity details should be confirmed directly from the venue's legal page (app.opinion.trade/terms) before relying on them for compliance purposes.
