Market Making Online Assessment Prep

Preparation for timed market-making or trading-game-style online assessments, including mental math, state tracking, quote speed, and review.

Candidates facing online rounds with quote, game, or fast decision elements.

Train timed decisions

Online assessments can reward clean decisions under time pressure. Practice the full loop: estimate, quote, update, and move on.

Keep arithmetic simple

Use approximations when exact precision is not required. The goal is usually a defensible quote, not a decorative calculation.

Concrete drill

Set a two-minute timer for ten binary-event quotes. For each, state probability, fair value, spread, and one reason for width.

Review immediately

After the timed block, classify misses into arithmetic, model, spread, state tracking, or overthinking. Then rerun only the weakest category.

Common mistakes

Candidates often chase speed before the method is stable. Build a repeatable quote routine first, then compress the time.

Practice the pattern

Use the LeetQuidity curriculum and calibration to turn this topic into a focused practice plan.
