## Fix trade still open after a manual exit on the exchange ## Destructive queries
Queries that write to the database.
These queries should usually not be necessary as freqtrade tries to handle all database operations itself - or exposes them via API or telegram commands.
!!! Warning
Please make sure you have a backup of your database before running any of the below queries.
!!! Danger
You should also **never** run any writing query (`update`, `insert`, `delete`) while a bot is connected to the database.
This can and will lead to data corruption - most likely, without the possibility of recovery.
### Fix trade still open after a manual exit on the exchange
!!! Warning !!! Warning
Manually selling a pair on the exchange will not be detected by the bot and it will try to sell anyway. Whenever possible, /forceexit <tradeid> should be used to accomplish the same thing.
