Onyx Terminal charges a dynamic fee based on the following formula: Fee=0.07×Notional Volume×Price×(1−Price)\text{Fee} = 0.07 \times \text{Notional Volume} \times \text{Price} \times (1 - \text{Price})

​
Explanation

  • 0.07: The base fee multiplier (7%).
  • Notional Volume: The total value of the trade.
  • Price: The execution price of the outcome token.
  • (1 - Price): Factor that adjusts fees based on the probability of the outcome.
This structure ensures fees are proportional to both the volume and the volatility/uncertainty of the market position.
