# Oku Trade Trading volume Methodology

## 1. Overview

Trading volume measures the total USD value of all swaps executed on Oku Trade, a decentralized exchange operating on the XDC blockchain using Uniswap V3-style automated market maker (AMM) technology. The metric aggregates daily swap activity by converting token amounts to USD values and applying anti-manipulation filters to ensure data quality.

## 2. Data sources

- **XDC blockchain event logs**: Parsed `Pool_Swap_event` logs from Oku Trade V3 pool contracts containing individual trade data including token amounts, sender addresses, and transaction details
- **XDC blockchain factory events**: Parsed `Factory_PoolCreated_event` logs from the Oku Trade V3 factory contract identifying valid trading pairs, token addresses, and fee tiers
- **Token metadata**: Token decimal precision and symbol information for proper amount conversion and pair naming
- **External price data**: End-of-day token price feeds providing USD conversion rates for all traded tokens

## 3. Step-by-step calculation

### Component A: Raw trade extraction
- **Purpose**: Extracts individual swap transactions from XDC blockchain event logs
- **Logic**: Processes `Pool_Swap_event` logs from Oku Trade V3 pool contracts on the XDC chain. Each event contains the pool address, sender address, and signed token amounts for both tokens in the pair. The raw amounts represent the change in token balances during the swap, with positive and negative values indicating direction of the trade
- **Key fields**: `block_timestamp` for trade timing, `transaction_hash` and `log_index` for unique identification, `address` as the pool contract, `sender` as the user executing the swap, `amount0` and `amount1` as raw token amounts with directional signs

### Component B: Trading pair registry
- **Purpose**: Builds a comprehensive registry of valid trading pairs with metadata
- **Logic**: Processes `Factory_PoolCreated_event` logs from the Oku Trade V3 factory contract to identify all legitimate pool addresses. Each event contains the two token addresses, pool address, and fee tier. Joins with token metadata to obtain decimal precision for both tokens and creates human-readable pair names using token symbols
- **Key fields**: `pool` address as the AMM contract, `token0` and `token1` addresses for the token pair, `fee` tier for the pool, token decimals for amount conversion, and concatenated symbol pairs for identification

### Component C: Trade processing and USD conversion
- **Purpose**: Combines raw trades with pair metadata and converts to USD values
- **Logic**: Joins swap events with the trading pair registry using pool addresses to obtain token context. Applies absolute value to raw token amounts to handle directional signs, then divides by 10 raised to the token's decimal precision to get actual token quantities. Performs USD conversion by joining with end-of-day price feeds for both tokens in each pair. Applies an anti-manipulation filter using the minimum USD value between the two token amounts in each swap to prevent inflated volumes from price manipulation attacks
- **Key fields**: Corrected `token0_amount` and `token1_amount` after decimal adjustment, `price_usd` from price feeds, and calculated USD values for both tokens with least-value selection

### Final aggregation
- **Combining components**: Sums all individual swap USD values grouped by day, chain, product version, and trading pair characteristics
- **Currency conversion**: Uses end-of-day token prices matched by timestamp, chain, and token address for consistent USD valuation across all swaps
- **Time aggregation**: Truncates trade timestamps to daily boundaries using `timestamp_trunc(day)` and aggregates all swaps within each 24-hour period
- **Final calculation**: The trading volume equals the sum of the minimum USD value between token pairs for all swaps in the time period, providing a manipulation-resistant measure of actual trading activity
