Market Making Endgame Interview Strategy

Market making endgame interview strategy for finite-round games, inventory unwind, final marks, and remaining risk budget.

Candidates in finite-round trading games.

Endgame changes priorities

Near the end of a finite game, inventory unwind, final mark, and remaining risk budget can matter more than long-run flow.

Know the final scoring rule

If inventory is marked at the end, carrying risk into the final state can help or hurt depending on the mark and position.

Concrete example

If one round remains and you are long near a position limit, you may quote to reduce inventory rather than maximize new spread capture.

Risk budget shrinks

With less time to recover, large new exposures may be harder to justify.

Do not always flatten blindly

Reducing risk is often sensible, but the correct endgame move depends on score, position, fair value, and rules.

Common mistakes

Candidates often use the same quote policy at the end as at the start. Time remaining is part of the state.

Practice the pattern
