| Trading Volume    | Using <code>FillOrder</code> or equivalent event, sum the amount traded each day or pulled directly from APIs provided by each protocol. | On-chain events or API                                                                                                                                                          | TRADING\_VOLUME   |

| ----------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | --------------- | ----------------- |
| Trading Volume    | Trading volume is filtered using a blacklist to remove pools that trade tokens that do not follow the ERC-20 standard as well as are extremely illiquid and not able to be properly priced. | On-chain events | DEX\_VOLUMES      |
| TVL               | TVL is filtered using a blacklist to remove pools that trade tokens that do not follow the ERC-20 standard as well as are extremely illiquid and not able to be properly priced.            | On-chain events | TVL               |
