SPOT
The ticket uses the latest GRT price. A buy spends USDT and adds GRT to your wallet. A sell does the reverse. Fills post immediately and show up under Orders with the price you saw on the ticket. If the USDT line is short, fund the wallet first — the form will say exactly how much is missing instead of failing silently.
Green rows are bids, red rows are asks, both from the public GRT book. They are there so you can see where size is sitting, not as a separate product. Hourly closes sit above the book so a one-minute print does not bully the whole view.
