IT - INET Nordic - PureStream on Nasdaq Europe, a new volume-based trajectory trading solution
Nasdaq Nordic is planning to introduce PureStream on Nasdaq Europe[1], a new volume-based trajectory trading solution in INET Nordic in Q1/2025 covering 13 European markets, pending regulatory approval. This innovative solution is designed to minimize market impact while maximizing liquidity from equal counterparts. PureStream matches Indications of Interest (IOIs) based on liquidity transfer rates (LTR), allowing members to automate the execution of trading interests by trading a percentage of the market's future volume at the market’s Volume-Weighted Average Price (VWAP).
PureStream complements and coexists alongside Nasdaq Nordic’s existing central limit order book, Nordic@Mid and Auction on Demand trading. There is no interaction between PureStream and existing trading methods.
PureStream trading will be offered for shares and depositary receipts (equities) primary listed in 13 regulated markets in Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, Netherlands, Norway, Portugal, Spain and Sweden. For Nasdaq Nordic listed equities, PureStream trading is offered from the respective Nasdaq Nordic exchange in Denmark, Finland and Sweden; and for selected European equities[2], from Nasdaq First North Sweden MTF where the equities will be admitted to trading for PureStream trading purposes only.
Members will have access to PureStream trading for their respective Nasdaq Nordic exchanges.
For more information, please visit PureStream on Nasdaq Europe website.
