Market Making Games Practice
A practice framework for market making games: quote logs, fair value updates, spread review, and inventory notes.
Candidates who need a repeatable way to improve market making games.
What good practice looks like
Good market making practice records the decisions, not just the score. Log your fair value, bid, ask, size, inventory, and reason for each quote. Without the log, you cannot tell whether a bad result came from poor pricing or normal variance.
Concrete example
If your first market is 40 at 60 and you sell repeatedly, write down whether you sold because your offer was too low, your spread was too tight, or the counterparty had better information. Each answer implies a different fix.
How to practice
Run short games, then review immediately. Mark one improvement target per session: initial estimate, spread width, quote update, inventory skew, or communication. Trying to fix everything at once usually fixes nothing.
Common mistakes
Candidates judge games only by profit and loss. Profit can be lucky and losses can be correct. Review decision quality, then use repeated sessions to see whether the pattern improves.
