Launch HN: OneChronos (YC S16) – Combinatorial auctions market for US equities
For those who want a rough programming analogy here -- this sounds like support for multi-row transactions in a SQL database where only single row edits were allowed before.Now you can describe "buy goods A and B at $10 maximum, commit" and have the transaction either succeed or fail. Before you had to edit those rows individually and there's risk that you end up in a weird partial state, hence having to lower your bid to cover your risk.Really exciting tech and it'll be great for these costs in market-making to be eliminated!
