The Gemini marketplace conducts auctions for certain trading pairs every day (including weekends and holidays), which foster moments of elevated liquidity and price discovery. The Auction file contains the auction-only order book for the 4pm ET BTCUSD, ETHUSD, or ZECUSD auction on the Gemini exchange on weekdays (non-NYSE holidays).
The auction-only order book supports both market and limit orders. These orders rest on the auction-only book until the auction runs. Auction-only orders may be placed up until the auction runs but may not be cancelled after the final indicative price is published at 3:50pm ET
Only auction-only orders that were explicitly accepted to the book show up in this file. Orders that were placed but rejected due to insufficient funds or self-cross do not show up in this file. There is not an explicit close event portrayed in this file. An auction-only order is closed and off the books when that order id is either cancelled or filled with no quantity remaining. Fill events are portrayed as a single rows for each order filled during the auction; both continuous book and auction book orders may be filled. Auction-only orders are distinguished by the Execution Option value auction-only.
