# Trading Volume for Alpha Markets on TermMax

## Calculation Logic

In practice, the trading volume is captured from the transaction events, specifically the **`SwapTokenToExactToken`** event. The calculation is as follows:

* Trading Volume = `tradingAmts` - `actualTokenIn/Out`
* Trading Value = `Trading Volume` \* `SNAPSHOT_PRICE` (of the respective token)

## Definitions

* tradingAmts: The total units of assets involved in the trade.
* actualTokenIn/Out: The actual net amount of assets transferred from/to the user (representing the Premium or Trading Cost).
* Trading Volume: The net amount swapped in the trade.
* SNAPSHOT\_PRICE: The USD market price of the respective token at the time the transaction was executed.

> **For Long positions:** This refers to the price of the Underlying Token (e.g., ESPORTS). 
>
> **For Short positions:** This refers to the price of USDT.
