## Functions

### cross

`function cross(int24 nextTick, bool zeroToOne) external` external

*Developer note: This function is called by the main pool when an initialized tick is crossed there. If the tick is also initialized in a virtual pool it should be crossed too*

| Name      | Type  | Description      |
| --------- | ----- | ---------------- |
| nextTick  | int24 | The crossed tick |
| zeroToOne | bool  | The direction    |

### increaseCumulative

`function increaseCumulative(uint32 currentTimestamp) external returns (enum IAlgebraVirtualPool.Status)` external

*Developer note: This function is called from the main pool before every swap To increase seconds per liquidity cumulative considering previous timestamp and liquidity. The liquidity is stored in a virtual pool*

| Name             | Type   | Description                       |
