# Sqrt Price Limit

In a **Concentrated Liquidity Market Maker (CLMM)**, the `sqrt_price_limit` parameter is used to define a price boundary for a swap — effectively acting as a **slippage protection mechanism**. Depending on the direction of your trade (i.e., which token you're selling vs. buying), you must use either a `min_sqrt_price_limit` or `max_sqrt_price_limit`.

**Determining Token Order**

Each CLMM pool defines a `token0` and a `token1`.\
You can identify the token order by using the `get_pool_view` function.

#### Swap Direction and Price Limits

| Trade Direction   | Use Limit              | Description                                                                          |
| ----------------- | ---------------------- | ------------------------------------------------------------------------------------ |
| `token0 → token1` | `min_sqrt_price_limit` | Sets a lower bound on the price to prevent excessive slippage when selling `token0`  |
| `token1 → token0` | `max_sqrt_price_limit` | Sets an upper bound on the price to prevent excessive slippage when selling `token1` |

**Example:**

If the pool consists of:

* `token0` = USDC
* `token1` = MOVE

Then:

* **Swapping USDC → MOVE**: Use `MIN_SQRT_PRICE`
* **Swapping MOVE → USDC**: Use `MAX_SQRT_PRICE`

#### Constants

```ts
export const MIN_SQRT_PRICE = "281480266797392";
export const MAX_SQRT_PRICE = "5192199275492655220258463701383891";
```

Use these constants to safely bound the swap and avoid undesired price execution due to rapid pool movement or low liquidity conditions.
