When transferring between the Wallet and a Fiat MT4/5 account, two conversions occur:
1. USD to Crypto (e.g., USDT): The platform uses a fixed 1:1 rate (1 USD = 1 USDT).
2. Fiat to USD:
- Inward (Wallet -> Trading Acct): Uses the platform's daily Deposit Rate.
- Outward (Trading Acct -> Wallet): Uses the platform's daily Withdrawal Rate.
Example: If you transfer 1 BTC to a EUR account, the BTC is converted to USD at the market rate, then converted to EUR at the daily deposit rate.
