How is the daily loss calculated?

When your account is created, it converts to a fixed dollar amount (100k 2-Step = 4,000 USD), and you see it in your dashboard. It is deducted from the higher of your balance or equity at the 23:00 CE(S)T rollover. It is evaluated continuously on equity, including floating losses, swaps and commissions – when you hit it, the engine automatically closes your positions.
