stillos-edge-gate

A callable trust primitive. Grade a track record before you commit capital.

A real edge is not a prediction — it is a repeatable, out-of-sample, fee-adjusted decision advantage that survives a regime change. This tells you, in one word, whether a strategy has one:

REAL_EDGE | REGIME_LUCK | NEGATIVE_EV | INSUFFICIENT_DATA

Fail-closed: anything that isn't a surviving, fee-adjusted, regime-stable edge is rejected. Every verdict ships with a signed, independently verifiable receipt.

npx stillos-edge-gate demo

Runs on bundled sample data and prints a real verdict + a real signed, verifiable receipt in one shot — nothing to set up first.

Install

npx stillos-edge-gate grade trades.json
# add --agent <name> to tag the receipt as you, not an anonymous caller
npx stillos-edge-gate grade trades.json --agent your-handle

or add as an MCP server (Claude Desktop / any MCP client):

{ "mcpServers": { "stillos-edge-gate": { "command": "npx", "args": ["stillos-edge-gate", "mcp"] } } }

Input

[ { "t": "2026-06-01T12:00:00Z", "price": 0.62, "side": "no", "outcome": 1 }, ... ]

price = entry price 0..1 · side = yes|no · outcome = 1 won / 0 lost.

How it decides

• chronological 70/30 out-of-sample holdout (most-recent 30% is the test)
• fee + slippage adjusted per trade
• significance test (t ≥ 1.5) on fee-adjusted EV
• REAL_EDGE only if +EV in both splits after fees, significant.

Why trust it

We ran it on our own live trading book first. It returned NEGATIVE_EV — and we published the signed receipt. We don't sell edges; we tell you whether yours is real.

Sample output

This is a real, live receipt from the free-tier /grade-strategy endpoint — not a mockup. Verify it yourself, no account needed:

{
  "verdict": "NEGATIVE_EV",
  "n": 120,
  "overall": { "wr": 0.55, "ev_net": -0.0718, "total_net": -8.62 },
  "train":   { "wr": 0.524, "ev_net": -0.098,  "total_net": -8.23 },
  "test":    { "wr": 0.611, "ev_net": -0.0107, "total_net": -0.38 },
  "t_stat": -1.57,
  "reasons": ["fee-adjusted EV negative overall (-0.0718/trade) and out-of-sample (-0.0107/trade) — loses money live"],
  "receipt_hash": "16ef2180d18359e1449062d0b6fb8cf780a2e6dfd2cb5ae201fce64cb4e7f59a",
  "verify": "https://nolawealthfinancial.com/notary/verify?hash=16ef2180d18359e1449062d0b6fb8cf780a2e6dfd2cb5ae201fce64cb4e7f59a"
}

verify resolves independently of us — hash_intact and signature_valid are recomputed on every request, not read from a cache.
