Why an auction — no sniping
A normal order book The fastest cable wins. Snipers pick off stale quotes; you race a clock you cannot see.
A frequent batch auction The book is sealed, then the whole beat clears at one price. Being first buys nothing — no sniping.
How the auction works
- Send an order — it rests in a sealed book, hidden from everyone.
- On a fixed beat the whole book clears together at one price.
- All fills take that one price, so speed does not pay.
