{"rules":{"max_picks":5,"window_days":7,"text":"Enter up to 5 universe symbols per round. Each pick locks the stored close on the round day and is scored a week later on its real 7-day return. Entries close at the next US session open after the round day (round.entries_close_at) so nobody commits on a return they can already see. Ranked by average return; the NEXUS screen competes as a row. Every row carries basis: 'live' means forward-scored rounds; 'backtest' means the screen's record reconstructed over stored closes after the fact, shown until it has forward-scored rounds of its own.
