# edgeX Perps Notional trading volume Methodology

## 1. Overview

Notional trading volume is defined as the total USD value of derivative contracts executed on edgeX Perps. This metric is utilized to assess the overall trading activity and liquidity on the platform, which is correlated with the generation of trading fees and protocol revenue. Trading volume is aggregated across multiple deployment venues, specifically StarkEx and EdgeChain. All values are denominated in USD.

## 2. Data sources

- **External data**: Daily trading statistics reported by the edgeX public REST API, covering StarkEx and EdgeChain

## 3. Step-by-step calculation

### Component A: edgeX Perps API data ingestion and deduplication

- **Purpose**: Retrieve and clean raw trading volume data from the edgeX API
- **Logic**: Raw daily trading data is ingested from the edgeX public REST API for both V1 (StarkEx) and V2 (EdgeChain) venues. To ensure data integrity, records are deduplicated by selecting the latest ingested entry for each combination of day and venue.
- **Key fields**: `day_timestamp`, `trading_volume_usd`, `venue`, `chain_id`

### Component B: edgeX Perps aggregation and normalization

- **Purpose**: Combine trading volumes across venues and format the metric for edgeX Perps
- **Logic**: Deduplicated trading volumes are grouped by day and chain, with the product type designated as edgeX Perps. The volume values, already denominated in USD, are cast to high-precision numeric formats. Missing records for any active days are handled to maintain a continuous daily time series.
- **Key fields**: `timestamp`, `chain_id`, `notional_trading_volume`
