# Why is market volume higher than mint volume?

When looking at `/loot` responses, you might notice that the sum of `total_volume_usd` across all markets is higher than the mint's `volume_usd`. This is expected behavior!

#### How Volume is Calculated

**Mint volume** counts each transaction once - it's the unique arbitrage volume for that token.

**Market volume** counts volume that flowed through each specific pool - and since arbitrages typically use multiple pools, the same transaction gets counted in each pool it touches.

#### Example

Imagine two arbitrage transactions:

**Transaction 1:** `SOL → Pool A → TOKEN → Pool B → SOL` ($100 volume)

* Mint gets: +$100
* Pool A gets: +$100
* Pool B gets: +$100

**Transaction 2:** `SOL → Pool C → TOKEN → Pool A → SOL` ($50 volume)

* Mint gets: +$50
* Pool C gets: +$50
* Pool A gets: +$50

**Result:**

| **Mint total**   | $150 |
| ---------------- | ---- |
| Pool A           | $150 |
| Pool B           | $100 |
| Pool C           | $50  |
| **Sum of pools** | $300 |

The sum of pool volumes ($300) is double the mint volume ($150) because each 2-leg arbitrage counts the full amount in both pools.

#### Why This is Useful

Market volume tells you "how much value flowed through this specific pool" - which is useful for:

* Identifying the most active pools for a token
* Understanding which pools are frequently used in arbitrage routes
* Ranking pools by trading activity
