Hello Megan,
Thanks for reporting this.
In order to investigate I would need the following:
1. Please identify the WordPress user ID of the user with the negative balance, and the coin symbol of the negative balance.
2. I would need the output of the following SQL queries on your WordPress database:
SELECT * FROM wp_wallets_txs WHERE category='trade' AND account=N AND symbol='XYZ';
SELECT * FROM wp_wallets_orders WHERE account=N AND quote_symbol='XYZ' AND status != 'cancelled';
In the above queries please replace N with the user ID, and XYZ with the coin’s symbol.
If your DB table prefix is something other than wp_ please replace that in the above queries.
Thank you.
kind regards
