Competition seasons
The Hidden Market Challenge
Every entrant trades the same hidden market with a $1M book. One regime, revealed at the end, so the ranking is pure skill. Divisions for individuals, clubs, and schools, and a placement in any of them is a resume line, the way dean's list is, with proof attached.

Why it matters
Every trade you make and every thesis you write is recorded. You walk away with a body of real decisions you can defend: how you handled a crash you did not see coming, why you shorted a name, when you moved to cash.
That is what you bring to an interview instead of “I'm passionate about markets.” And the market for finance seats has never been tighter.

The loop
How it works
Four steps. No shortcuts.
Choose your sector
Pick a focused universe of real tickers, from Technology to Macro. Real companies, real prices.
Trade a hidden market
Real historical prices, charts, and fundamentals, with the dates hidden. No idea what year it is or what the news said. Every call is yours.
Reveal the regime
When you are ready, unmask the dates. Your run is scored against the market: return, alpha, Sharpe, and drawdown.
Own your decisions
Every trade and thesis becomes a certified track record. Timestamped, verifiable, and yours to walk through in an interview.
Integrity
Built so it cannot be faked
A track record is only worth what it costs to fake. Ours is expensive.
Hidden dates
You trade real historical markets without knowing the year. No hindsight, no looking up what happened next.
Scored on our servers
Returns, alpha, Sharpe, and drawdown are computed server-side against the actual market. Nothing is self-reported.
One attempt per market
Certified runs cannot be replayed until the result looks good. The first take is the record.
Paced by design
Certified runs allow three advances per real day. A record takes days of returning and sitting with your decisions, not one afternoon of clicking.
Audiences
