How it works

Making sense of the board

The top of the page leads with the two figures most visitors want first: where USDT is cheapest to buy, and where it pays the most to sell. Below that, each exchange gets its own row with its top offers, so the gap between them is easy to see.

The spread

The spread is simply the best buy price minus the best sell price — the cost of buying and immediately selling back. A tight spread points to an active market. A wide one usually means either a slow hour or a market that has just moved fast.

Comparing against the official rate

The official figure comes from published currency feeds. The street figure is what people are actually paying. The percentage gap between the two says more about the day than either number on its own, which is why it sits on the homepage instead of being buried further down.

Update frequency

Prices refresh roughly every ninety seconds, and the age of the board is always printed beside it. If every exchange goes quiet at once, the last working board stays up with its age shown, because a number from a few minutes back still beats a blank page.

Minimums and maximums

Peer to peer listings carry a floor and a ceiling, shown wherever the exchange publishes them. A great rate attached to a minimum well above what you are changing is not a great rate for your trade.
