For example, if an option is traded at $1 (ETH at $1k), the fee will be $0.125 (instead of $0.3) Hence, trading fees can be defined as:\ `min((taker or maker * qty * index_price), (0.125 * option_price))` #### Example Scenario Symbol: ETH-30DEC22-1500-C\ Type: ETH Call Option\ Underlying: ETH\ Current Price: $1000\ Strike Price: $1500\ Quantity: 1 contracts\ Expiration Date: December 30, 2022\ Premium: 20 USDC User A sets a **limit sell order** for 1 ETH-30DEC22-1500-C contract, with price 20 USDC. User B places a **market buy order** for 1 of the same contract, and pays the 20 USDC premium. Trading fees paid by User A (Maker):\ `min((0.03% * 1 * $1000), (0.125 * $20)) = min($0.45, $2.5) = $0.45` Trading fees paid by User B (Taker):\ `min((0.05% * 1 * $1000), (0.125 * $20)) = min($0.75, $2.5) = $0.75` ### Settlement Fees When options expire in the money, there is an exchange of cash between buyers of the option and sellers of the option. Aevo charges a **0.015%** settlement fee on the **notional** of the option that expired in the money. This fee is charged to the holders of the option at expiry. Settlement fees can never be higher than 12.5% of the option's value. **Settlement fees are also not charged for Daily Options.** #### Example Scenario Symbol: ETH-30DEC22-1500-C\ Type: ETH Call Option\ Underlying: ETH\ Current Price: $2000\ Strike Price: $1500\ Quantity: 1 contracts\ Expiration Date: December 30, 2022 User A holds 1 contract of ETH-30DEC22-1500-C, which is in-the-money at expiry. Settlement Fees paid by User A:\ `min(0.015% * 1 * $2000, (0.125 * ($2000-$1500)) = min($0.3, $62.5) = $0.3` User B holds 1 contract of ETH-30DEC22-2500-C, which is out-of-the-money at expiry. User B pays no settlement fee. --- # Agent Instructions This documentation is published with GitBook.
