Definition Ref.

Note
Closing a long position in a security would entail selling it, while closing a short position in a security would involve buying it back. The difference between the price at which the position in a security was opened, or initiated, and the price at which it was closed, represents the gross profit or loss on that security position. Taking offsetting positions in swaps is also very common to eliminate exposure prior to maturity.

The final method of closing a position is referred to as dealer or broker liquidation, which is when the broker/dealer closes the position rather than the trader doing so. In these instances, some or all of a trader’s open positions are closed by the Forex dealer as the result of the trader falling below the margin requirement.
