# Self-Trade Prevention

When a new order attempts to match with a resting order placed by the same account, the existing order is cancelled, and the new order proceeds as per normal.\
\
This makes sure that no trades will happen between orders from the same account.\
\
The removed order will be labelled as "Rejected" under the "Status" column in order history.
