Grade the thinking, not the luck
A good analysis can lose and a bad guess can win. We score your process, so you learn skills that last.
Real data, hidden future
Practice on real history. The days after the cutoff stay on the server until you commit to an answer.
AI teaches, never trades
While apps race to trade for you, our AI only explains and grades. You stay the one who decides.

Each one is graded the moment you submit.
