Every day everyone gets the same generated session from 9:25 to 11:00 New York time, with the same rules: MNQ, up to 5 contracts and a $500 daily loss limit. You get one try. Your result is checked on the server against the market data and ranked by net P&L, then fewer trades.
You can hide your username on the leaderboard. It's just for fun, there are no prizes.
