Delegation basically talks about lending Sp to someone or receiving from someone, therefore the types of delegation are ; incoming and outgoing delegation.

These show the outgoing and incoming delegations for your account. When you are delegated steem power that is termed as an incoming delegation and can be viewed under the incoming delegation option. The outgoing delegations are the Steem power delegations that have given shared with other accounts and they are displayed under the outgoing delegations option. The delegation time of initiation is automatically recorded down. You can also automate the expiry date of the outgoing delegation such that it comes back to you.
