## Taker Fee Structure
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. Fees are highest at 50% probability and lowest at the extremes (near 0% or 100%).
Taker fees are calculated in USDC and vary based on the share price. However, fees are collected in shares on buy orders and USDC on sell orders. The fee amount in USDC is symmetric around 50% probability — a trade at 30¢ incurs the same dollar fee as a trade at 70¢.
