How fees work
Every number below is read live from our fee engine — what you see here is exactly what the platform charges.
Source of truth: code. This page renders the live fee schedule, and a test keeps our fee document in lockstep with it — the rates can't silently rot.
Volume-based maker/taker tiers
Your tier is set by your rolling 30-day trading volume. Higher volume, lower fees — the top tier even earns a maker rebate.
| Tier | 30-day volume | Maker | Taker |

Volume is your total traded value over the trailing 30 days (a daily rollup, with a live fallback for brand-new traders so you're never under-tiered). Tiers refresh hourly and are warmed at login, so your first trade already reads the right rate. Admins can apply a global override, which then wins over the tiered rates.
Worked examples
Settlement, void, withdrawals & rounding
Voided markets: If a market is cancelled, your stake is refunded in full. Trading fees already charged on earlier fills are not clawed back — they were the cost of trades that really happened.
Withdrawals: There is currently no withdrawal fee. Any fee is always shown, to the cent, before you confirm.
Rounding: All money is handled in exact cents (never floating point). Fees round up to the cent and rebates round down — always in the house's favour — so totals reconcile exactly.
Where you'll see it: The fee is shown in the order ticket before you confirm, on the trade receipt, and on the transaction in your history — the same number every time, and the same amount booked to our ledger.
