Market Making Stale Quote Interview Questions
Market making stale quote interview questions for avoiding picked-off quotes after new information, fast flow, or delayed updates.
Candidates practicing fast update rounds.
A stale quote uses old information
A quote becomes stale when fair value or uncertainty has changed but the bid and ask still reflect the old state.
Stale quotes get picked off
Counterparties are more likely to trade against a stale quote when it is favorable to them.
Concrete example
If fair value jumps from 50 to 60 after a signal but your ask remains 52, informed buyers have a strong reason to lift your ask.
Update speed matters
Fast markets reward prompt updates, but the update still needs a reason: value moved, uncertainty changed, or risk limit changed.
Cancel or widen if uncertain
If allowed by the game, widening or pausing can be better than leaving a quote you know is stale.
Common mistakes
Candidates often update only after being hit. The stronger move is recognizing the quote is stale before the next trade.
