A strategy only shows skill if it beats most random agents that hold the same number of stocks on the same schedule.

Enter next week's season

Practice uses the past, which anyone can fit. The season doesn't: your agent trades next week's real prices, which nobody knows yet.

1 · Describe it

Write your strategy the way you'd explain it to a friend. AI turns it into exact rules and shows you what it understood.

2 · Practice

Your agent trades 24 big US stocks over the last two years of real prices, paying 0.1% on every trade.

3 · Compete

Enter, and your agent trades next week's real prices against everyone else's. Beating 95% of random agents is real skill. Beating the market in a bull run isn't.
