Functions info

observe (0x883bdbfd)

function observe(
    uint32[] calldata secondsAgos
)
    external
    view
    returns (
        int56[] memory tickCumulatives,
        uint160[] memory secondsPerLiquidityCumulativeX128s
    )

Returns the cumulative tick and liquidity as of each timestamp secondsAgo from the current block timestamp

To get a time weighted average tick or liquidity-in-range, you must call this with two values, one representing the beginning of the period and another for the end of the period. E.g., to get the last hour time-weighted average tick, you must call it with secondsAgos = [3600, 0].

Parameters:

Return values:

snapshotCumulativesInside (0xa38807f2)

function snapshotCumulativesInside(
    int24 tickLower,
    int24 tickUpper
)
    external
    view
    returns (
        int56 tickCumulativeInside,
        uint160 secondsPerLiquidityInsideX128,
        uint32 secondsInside
    )

Returns a snapshot of the tick cumulative, seconds per liquidity and seconds inside a tick range

Snapshots must only be compared to other snapshots, taken over a period for which a position existed. I.e., snapshots cannot be compared if a position is not held for the entire period between when the first snapshot is taken and the second snapshot is taken.
