1. The physical place on an
exchange where
transactions occur. Posts are most important to exchanges that use the
open outcry or a similar system. They are becoming increasingly irrelevant as more exchanges conduct
trading electronically. Posts are also called
trading posts.
2. To recognize a
transaction on an account. For example, if one writes a
check for $100 and $100 is deducted from that account three days later, the transaction is set to post on the third day.
