Market Making Peer Practice Guide
A guide to running market-making peer practice with roles, prompts, quote rounds, scoring, feedback, and targeted repair drills.
Candidates practicing trading games with classmates, study groups, or interview peers.
Assign clear roles
One person runs the prompt, one quotes, and one observes if the group has three people. Rotating roles keeps feedback grounded in the same rules.
Keep the game state visible
Track fair value, quotes, fills, inventory, score, and signals. Without shared state, feedback becomes vague and disputes replace learning.
Concrete session
Run ten quote rounds, then review three moments: first quote, worst fill, and best update. End by assigning one drill for the next session.
Feedback should be behavioral
Good feedback says what happened: quote too tight after uncertainty rose, inventory not mentioned, or update reason unclear.
Common mistakes
Peer sessions often become casual games. Keep timing, state, scoring, and review explicit so the session improves interview behavior.
Practice the pattern
