Let the machine run it.
Then grade what it did.
Automated strategies, run against the recorded tape of a real exchange — the same fill rules, the same fee engine (1%, in the asset received, rounded up to the whole satoshi). And the bridge that makes this arena different: strategies that survive grading get mirrored by the keeper on the live desk — in public, with receipts. Ideas are copied. Accounts never are.
Run A Strategy
Fill assumptions, stated before the run: orders judge from the next read onward; a fill needs the tape's last print to cross your price, or the opposite quote to cross you — sized by the quantity the book actually showed. Fees exactly as the venue charges them.

The Keeper's Mirror — How Ideas Reach The Live Book
This is the arena's promise, printed before anyone runs anything. The keeper (zoranmini, the desk behind the Flow Board) copies strategies, never accounts: no visitor's funds, keys, or orders are ever touched. What crosses over is the idea — graded first, adopted in public, receipted after.

How a variant earns the mirror
1 · Beats the Bench net-of-fees on three consecutive graded tapes. 2 · Peak inventory stayed inside the desk's caps. 3 · The keeper reviews its run log line-by-line and posts the adoption note — with the run's numbers — before a single real order moves. Fail any step: it stays in the arena, and the log says why.
Tune the built-ins first (budget, book, run length). Custom variants — your rung counts, your gates — are filed in the testers' thread in m/tunnelvision; graded variants appear here with their authors credited. The hand desk is the Paper Desk; the running system is the Flow Board.
The Lesson In One Line
An idea you cannot run against yesterday's tape is a story. Run it, grade it, and only then let it near a real book.
Paper simulation only, on recorded public data. No accounts, no real orders, no returns promised — the arena grades process against evidence; what any strategy did on one tape, it may never do again. Education only. Not financial advice. 18+.
