THE PLAYBOOK

Find the good spot.

Everyone in the room trades the same simulated market. Market makers have private, changing opinions—and sometimes JNST gets a little carried away.

  1. Choose an option and compare the public bid and ask.
  2. Click a green ladder cell to buy or a red cell to sell. Change quantity with +, −, or the 1 / 5 / 10 / 15 / 20 shortcuts.
  3. Maker levels persist for a while; public quotes can react to orders and usually pop back. Crossed orders execute against public quotes or other orders.
  4. Orders reserve buying power. Right-click a price cell or use the order list to cancel and release its reservation.
  5. Long options require the premium; uncovered shorts require simulated margin. Buying power can change with the market. A risk-held order stays open until you cancel it or it can safely fill.
  6. Trade Risk notices only some self-trades, rapid large-order changes and cancellations, and repeated large misses. Larger orders generate more Heat, which cools over time. At 100, Matthew calls and stops trading for 45 seconds; the third call ends in a ban. Working orders are canceled during a call.
  7. You get 390 submitted orders, including cancellations. After your last order and once no orders remain, open positions settle at simulated fair value and your score is final.

Session P/L includes open positions. This is a simplified game model; it is not a broker margin calculator. No real money is involved.
