LiquidityThresholdAssetManager

This is an abstract implementation of the IAssetManager interface that implements a liquidity strategy based on thresholds.

This strategy manages how much of the funds should remain liquid in the reserve (currency().balanceOf(reserve)) and how much is invested. For that, it has three liquidity thresholds: minimum, middle, and maximum. On the rebalance operations, if the liquid funds of the reserve are above the maximum, it invests funds, leaving liquidity at the middle level. If the liquid funds are below the minimum, it deinvests enough funds to leave the liquidity again at the middle level.

Inheriting

The contract does not implement the specific investment strategy, that must be implemented by descendant contracts. These contracts must overload at least the functions _invest(amount), _deinvest(amount), deinvestAll(), and getInvestmentValue().

Parameters

Field	Type	Description
liquidityMin	uint256 (amount)	Minimal amount of liquid funds the Asset Manager tries to leave in the Reserve. If under this value, deinvests.
liquidityMiddle	uint256 (amount)	Target amount to which the liquid funds of the reserve are taken after a rebalance operation
liquidityMin	uint256 (amount)	Maximum amount of liquid funds the Asset Manager tries to leave in the Reserve. If above this value, invests.
