The liquidity is the available balance that can be sent across the channel in one direction as reminded here below (source [lnbook](https://github.com/lnbook/lnbook)) `Liquidity(NodeA) = balance(NodeA) - channel_reserve(NodeA) - pending_HTLCs(NodeA)` The channel i*nbound liquidity* is the amount of bitcoin that a node can receive through that channel. The channel o*utbound liquidity* is the amount of bitcoin that a node can send through that channel. Note: We make a difference between the inbound/outbound liquidity at a channel level and at a node level. The inbound/outbound liquidity of a node will be the sum of inbound/outbound liquidity of all its channels and can be monitored with [Node balance](/readme/liquidops/integrations/triggers/node-balance.md) trigger. The channel balance trigger can be configured by selecting 2 parameters : Liquidity type: Inbound or Outbound Threshold: expressed in % --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
