The marketplace

The marketplace is where strategies live publicly. Anyone with an Engine account can browse it. Anyone with a deployed strategy can publish to it. The whole point is to make edge legible: when a strategy works, anyone can read exactly what it's doing.

Browsing

The marketplace is at /marketplace and inside the dashboard. Each card shows:

• Name and author handle. Authors are anonymous by default.
• One-line description of what the strategy is doing.
• 30-day P&L and max drawdown, computed across all live subscribers' actual fills. Real numbers, including slippage and fees. But also a small sample. Read with skepticism.
• A "verified" badge if Engine has reviewed the strategy for malicious patterns. Verified means it's safe to run, not that it'll be profitable.
• An "aggressive" badge on strategies with large drawdowns or high leverage. Read the file before subscribing.

Click any card to inspect the public bundle and the strategy's recent decisions in production. Secret values are never shown.

Subscribing

Subscribing rides the author's published version. When they update the bundle, you get the update automatically. You can't edit a subscribed strategy's files. If you want to tune one to your taste, write your own from scratch using Building your own as a guide.

Subscribing costs exactly the same as running a strategy you wrote yourself. Authors don't set their own fee rate, and they don't take a cut. See How fees work.

What "verified" means

Verification is a safety check, not a quality check. We look for market-manipulation patterns, sanctions evasion, routing to blocked entities, and strategies that misrepresent themselves.

We don't check whether the strategy is profitable, whether its rules are sound for any particular regime, or whether the author is who they say they are. Treat verified as "this won't get you in trouble," not "this is good."

Publishing your own

Once your strategy has been running for at least 30 days with positive cumulative P&L, you'll see a Publish option on the strategy detail page. You write a public description, and that's it. Your bundle is live for others to subscribe to. Declared tools and data source endpoints become public; secret values stay private.

Publishing is reversible. Unpublish any time. Existing subscribers get 7 days to switch or move before access ends.
