the price of is either decreasing or increasing and the user wan't not to miss the opportunity however he can't change his possition as multiplier is 0

Summary

During the initialization of the pool initial weights is being set with initial values for both

• lastPossibleInterpolationTime

• lastUpdateIntervalTime
  to block.timestamp

This is the apply in _setInitialWeights called from initialize

So initial multiplier is zero

Updating weights might be 1 hour or 1 day depends on updateInterval value
during that time weights move according to multiplier and time since lastupdate in the initial state till the update it will always be zero

during this time there is a severe issue where any swaps from or to the pool weights won't change causing loss of opportunity to LPs

Scenario

Assume pool with of 2 tokens USDC and WETH with weights:

• WETH = 6.97e17

• USDC = 3.03e17

A huge drop of eth price happen in the time between initialization and update

the eth price became 1300 no reflection happens to the weights in the pool users can't swap nor add or remove liquidity due static weights losing opportunity for users

The time of impact depends on updateInterval value.

Impact

Loss of opportunity as weights won't get changed in this period
