This is an order Trality's positioning system creates when it detects a mismatch between the balance we're getting from the exchange and the one we're expecting given your orders. This normally occurs if a user withdraws money or adds funds to their exchange account.
It can also automatically occur when you start the bot that has assets with balances > 0 on any asset other than the quoted asset, in which case the position will be evaluated at current market rates using a foreign market order.
