You Make the Market

Quote a bid-ask spread. An informed trader will exploit mispriced quotes.

How it works

You see some dice face-up and compute the expected sum
You quote a bid (price you'll buy at) and ask (price you'll sell at)
An informed trader who sees all dice decides to trade against you or pass
If your spread contains the true sum, you earn a bonus for quoting a fair market
If the true sum is outside your spread, the trader exploits you

Tight, well-centred spreads earn the most. Off-centre or too-narrow spreads get picked off.
