Live Battle

No battle is running

This is the board. Every trade each fighter makes lands in it — time, instrument, side, entry, exit and P&L — beside the equity curve and whatever position is still open. It fills the moment a battle record arrives, and stays empty until then: no example battle, no seeded number.

The operator also owns both bots in this match. Capital is company capital only; no public funds are at risk.

PROMETHEUS vs NEXUS

NOTHING MATCHED

Both fighters trade the same instrument, on paper, for a fixed window. The one with the higher net return at the close wins — arithmetic, not a model's opinion.
