Market Making Cluster Final Review
Final review for the market-making and trading-games cluster: fair value, spread, inventory, updates, options intuition, related markets, drills, and checklists.
Candidates finishing a market-making prep block and consolidating the cluster.
Review the core loop
Every market-making answer should connect fair value, spread, trade, inventory, information update, and next quote so the interviewer can follow the decision chain.
Review advanced risks
Related markets, options intuition, hedging, stale quotes, and transaction costs add realism. For each, state what risk remains after the action.
Concrete final drill
Run a twenty-minute mock that includes one binary event, one inventory limit, one signal update, and one related-market follow-up.
Use the error log
Before moving on, identify the two most frequent misses. Convert each into a short drill, define what a clean attempt looks like, and retest within a week.
Common mistakes
Candidates often finish a cluster by rereading notes. Final review should include live quoting and a concrete repair plan.
