Auction on Demand
Trade Large Orders Discreetly With Minimal Market Impact
Periodic Auctions
Periodic auctions are used as an alternative to OTC and dark pool trading. Periodic auctions execute separately from the lit order book with no impact on continuous lit trading. No information about individual orders is published, making Auction on Demand ideal for large or strategically important orders where you want to keep information about trading interests confidential.
Key Benefits

Benefit from the Auction model at any time during trading hours. Auctions are triggered on demand, whenever matching orders are found
Minimized Market Impact

Multiple Safety Features
Randomized uncross and speed bumps on cancels and modifications secures that only real trading interests are entered in the book
How Auction on Demand Works
Auctions are triggered on demand as soon as two crossing orders are found by the system. An auction starts with a fixed 25 ms period, followed by a random period of between 0 and 75 ms, so that the auction stays open for a maximum of 100 ms. During this time other bids may enter the system and take precedence.
The auction will uncross at the price where the most volume can be traded. Price and executable quantity are published in real time.
Priority model: Internal (broker)/size/time.
