# Acala DEX Trade count Methodology

## 1. Overview

Trade count measures the number of trades executed on Acala DEX. This metric highlights the frequency with which users interact with the decentralized exchange's liquidity pools to swap assets. It serves as a key indicator of user engagement and transaction activity within the Acala Substrate ecosystem.

## 2. Data sources

- **Blockchain events**: `Swap` events from the `dex` pallet, covering Acala Substrate

## 3. Step-by-step calculation

### Component A: Acala DEX swap extraction

- **Purpose**: Identify and isolate successful trading activity from the Acala blockchain.
- **Logic**: `Swap` events are parsed from the `dex` pallet on Acala Substrate. The dataset is filtered to include only successful transactions by verifying the status of the associated extrinsic. Transaction-level metadata is retrieved for each event to identify unique trade instances.
- **Key fields**: `extrinsic_id` (transaction identifier), `event_method` (event type), and `success` (transaction status).

### Component B: Trade count aggregation

- **Purpose**: Generate a daily total of unique trading transactions.
- **Logic**: The number of unique transaction identifiers is calculated for each 24-hour period. This approach ensures that the metric reflects the count of distinct trade transactions rather than the raw number of sub-events within a single transaction. All data is aggregated using UTC day boundaries.
- **Key fields**: `extrinsic_id` (unique identifier).
