# Fees

> Platform and Protocol Fees

Onyx Terminal charges a dynamic fee based on the following formula:

$$
\text{Fee} = 0.07 \times \text{Notional Volume} \times \text{Price} \times (1 - \text{Price})
$$

### 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.
