Market Making Related Markets Interview
Market making related markets interview guide for updating one quote after trades, signals, or fair-value changes in another market.
Candidates practicing multi-market quote updates.
Related markets share information
A trade or signal in one market can update fair value, uncertainty, or hedge value in another related market.
Identify the link
Before updating, state why the markets are related: common driver, payoff overlap, hedge relationship, or statistical correlation.
Concrete example
If a trade suggests higher probability for an event, a related conditional event may also need a higher quote, but not necessarily by the same amount.
Track inventory across markets
Positions in related markets can offset or amplify each other. The risk view should include the combined exposure.
Avoid one-for-one updates
Related does not mean identical. Explain the strength and direction of the update.
Common mistakes
Candidates often update only the market that traded. In related markets, the untouched quote may also be stale.
