is_input

val is_input: boolean(source)

Since it refers to the other chain, if this value is true, this movement of tokens went into the transaction, out of the account and out of the other chain. It then went into the current chain, and into the account that received it, which is however stored in a transfer_history_entry which will have is_input set to false.
