Who builds Coil, and the rules it's built under

What Coil is

Coil (coil.trade) is a rules-based, long-only stock scanner and trading engine that finds market leaders at real pullbacks. Two subscriptions: Coil Scanner ($12/mo or $99/yr) is the scored board, read in your browser, covering every name across the S&P 500, the Nasdaq-100, and a macro book (bonds, income, gold & metals, commodities). Coil Live ($29/mo or $249/yr) serves the engine-grade board over MCP to your own AI agent, which places any orders at your own broker; Coil never holds accounts or keys. The full story is on how it works.

Who makes it

Coil is built and operated by one engineer, Joey Fife — the same person answers support@coil.trade, writes the code, runs the system on his own account, and posts as @coil_trade (public profiles: LinkedIn, GitHub). There is no team page to inflate and no office to photograph. The trade-off is honest: you get software built with the care of someone who runs it on his own money, and support that is one person deep.

The honesty rules

Trading tools attract loud claims, so this site binds itself to quieter ones. Every page here follows the same rules:

• Every performance number appears next to its benchmark. The headline backtest — +638% for 2017–2026 H1 vs SPY's +282%, survivorship-free — always travels with its rider: through end-2025 it ran roughly even with SPY at about one-third less drawdown; the outperformance concentrates in leadership regimes.
• Backtested is labeled backtested. Research figures are not live results and not client returns. The engine is newly live, and we say so.
• No return promises, ever. Markets can lose money; leveraged ETFs can lose value rapidly, including total loss. If a page here ever promises you profit, something has gone badly wrong — email us.
• The risk section lives on the homepage, not in a footnote. See straight answers.

What Coil is not

Not investment advice, not a managed account, not a signal-selling hype machine, and not a brokerage. Coil holds no customer funds and places no trades on anyone's behalf — it is self-operated software: your agent, your broker, your capital, your decisions. The scored board is served to agents as an MCP server at mcp.coil.trade/mcp; the engine that trades is software your own agent runs, on your machine.
