Help with account balances

[Xerxes7777]

how is the account balance associated with the user id??

I restarting my opentrade I need to clear all the users and start fresh without reinstalling the whole thing.
How can I clear the balance of the previous users??
The problem is despite /root/opentrade/accountsserver/database/sqlite_account.db and/root/opentrade/server/database/sqlite.db
the old balance gets back in these file when the use sign up again.
Where is the /root/opentrade/accountsserver/database/sqlite_account.db and/root/opentrade/server/database/sqlite.db gets updated from how can delete the previous account balances??
