ONLY EOA AND ALLOWED CALLER: Rebalance product. If |min leverage ratio| < |current leverage ratio| < |max leverage ratio|, then rebalance can only be called once the rebalance interval has elapsed since last timestamp. If outside the max and min but below incentivized leverage ratio, rebalance can be called anytime to bring leverage ratio back to the max or min bounds. The methodology will determine whether to delever or lever. If levering up, SetToken increases the short position on PerpV2, withdraws collateral asset from PerpV2 and uses it to acquire more spot asset to keep the position delta-neutral. If delevering, SetToken decreases the short position on PerpV2, sells spot asset on UniswapV3 and deposits the returned collateral token to PerpV2 to collateralize the PerpV2 position.
