Calibrate
Calibrate, $10K Market Crash Survivor & Optiver 80-in-8 Tra lets you trade simulated historical market crashes from a $10,000 starting bankroll, practicing fast trade decisions and benchmarking Optiver-style mental math under timed conditions.
Play CalibrateA fresh puzzle is waiting for you.
Calibrate combines Tape Blitz, a $10K Historical Crash Survivor scenario, with a suite of quant training tools. You start with a simulated $10,000 bankroll, ride breakout signals at leverage and move fully to cash before major crashes, all while running replayed historical market events to test crash survival rules and timing.
The site also bundles a free Optiver 80-in-8 mental math trainer, a Jane Street market-making spread simulator, an 80% Confidence Interval exercise, and a Kelly Criterion lab for position-sizing practice. The training modules focus on speed, probability judgment, and risk sizing to complement the crash-replay trading drills.
How to play Calibrate
- Open Calibrate and choose Tape Blitz or one of the training modules such as Optiver 80-in-8 or the Kelly Criterion lab.
- For Tape Blitz start a session with the $10,000 simulated bankroll provided by the game.
- Watch for breakout signals and enter positions using the platform's leverage or sizing tools, using 3x long setups during breakouts as the scenario suggests.
- Monitor price action and shift your portfolio to 100% cash before an implied historical crash to preserve capital.
- Use the free Optiver 80-in-8 module to practice rapid mental math under timed constraints between replay sessions.
- Try the Jane Street simulator and the 80% Confidence Interval exercise to refine market-making intuition and probabilistic reasoning.
Tips for Calibrate
- Treat the $10,000 start as real capital and size positions conservatively in practice to learn risk management.
- Use the recommendation to ride breakouts with leverage for momentum but set firm rules to move to cash before crash windows.
- Practice the Optiver 80-in-8 drills to improve calculation speed, which helps quick sizing and spread decisions in replayed crashes.
- Use the Kelly Criterion lab to test position-sizing approaches on historical runs before applying them in Tape Blitz.
- Work through the Jane Street spread simulator to build intuition about bid-ask behavior and market-making responses during volatile periods.
