What happens to the profit/loss of my open trade(s) when I transfer my cryptocurrency from the TBanque trading account to my TBanque Money crypto wallet?

The profit or loss of a position on the TBanque trading platform is part of the total value of the entire trade. When a transfer of coins from the TBanque trading platform to the crypto wallet is approved, the relevant position is closed in your TBanque trading account and the value of that trade (invested amount +/- profit/loss) is taken out of the account balance. The crypto is then sent to the wallet.
