# Coil > Coil is a rules-based, self-tuning trading engine for leveraged semiconductor > ETFs (SOXL / SOXS). You buy and download the packet, drop it into your AI agent, > connect your own brokerage, and it runs hands-off on your own machine — taking > entries, managing every exit by rule, and applying risk circuit-breakers, with > your own account and your own capital. It is software you operate yourself: not > investment advice, not a managed account, not a signal service, and not a > guarantee of profit. Leveraged ETFs can lose money rapidly, including total loss. ## How you run it - Drop the packet into your AI agent. Built for Claude (scheduled Claude sessions are the operator); adaptable to your agent of choice. The agent executes the engine and never rewrites its own validation standard. - It places trades through a broker connector — built for Robinhood; any broker with an equivalent MCP works. - Under the hood it's Python on macOS with a free Alpaca data key. You add your own broker account id and key; your credentials never leave your machine. - Setup is about an hour: drop in the packet, add your keys, run the 20 integrity guards, arm it. Then it's hands-off — and you can stop it in one command. ## What it does (the rules) - Entry ("leg-rider"): sustained 2%+ intraday semis moves are treated as short- timeframe reversals inside the 1-hour trend. Entry = 1h trend direction + entry-timeframe RSI washed against it + a fresh 9-SMA recapture, gated on tape energy. - Exit: a 0.8% counter-move in the underlying (≈2.4% trail on the 3× ETF) is the only soft exit; a 5% hard stop backstops gaps; inverse ETFs are never held overnight. - Risk: a persistent, disk-backed circuit-breaker ladder anchored to the account's equity high-water mark (−6% day halts entries; −10/−15% cuts size; −25% hard stop), plus a 65% single-symbol cap. These reduce big single-day damage; they do not remove risk. ## The two improvement loops (this is how the two tiers differ) - LOCAL loop (ships in EVERY copy, including the $5): nightly + weekly loops re-fit parameters and capital-multipliers to the buyer's OWN fills, within whitelisted bounds, with auto-rollback. It tunes the dials that exist. It cannot add new structure — no new entry lanes, no new exits, no new instruments — and it cannot repair a structurally weak regime. - CENTRALIZED R&D (the Pro subscription): an adversarial multi-agent research program discovers genuinely new validated structure — new lanes, new exits, new instrument sleeves, and the fix for the disclosed −8.3% chop cell — each cold-validated across 4 market regimes before it ships as a numbered version. Reduces strategy-decay risk; does not guarantee the edge survives. - In one line: "Your download gets smarter about your tape. Pro makes the strategy itself smarter." The local loop optimizes what you already own; Pro expands what there is to optimize. ## Validated performance (backtested / forward-tested, not client returns) - Two-way tape (2026, 250 days): +9.9%, profit factor 2.13, max drawdown 8.2%. - Bear market (2022, 250 days): +4.1%, profit factor 1.34. - Quiet bull (2023, 250 days): 0 trades — sits in cash, earns sweep. - Chop (2024, 250 days): -8.3% — disclosed weak cell, the lab's first R&D target. - Measured under true execution economics in fresh processes, one regime at a time. Past performance does not predict future results. The system also found and fixed its own three backtest bugs; 20 regression guards now protect the harness. ## Pricing - Download: $5 one-time. The complete self-tuning engine, yours to keep and run forever. - Pro: $25 / month. Every new validated version the lab ships, delivered automatically while subscribed. Cancel anytime and keep your last version. - Payments and downloads are handled by a merchant-of-record checkout (Lemon Squeezy). ## Requirements - An AI agent (built for Claude; adaptable to others) to operate it. - A brokerage with an automation connector (built for Robinhood; any equivalent MCP works). - macOS, Python 3.9+, and a free Alpaca account for market data. ## Important disclosures - Coil is not investment advice and not a recommendation to buy or sell any security. - Leveraged ETFs (SOXL, SOXS) can lose value rapidly, including total loss of capital. - You run Coil with your own credentials and your own capital, and you are solely responsible for your trading decisions. ## Links - Home: https://coil.trade/ - How it runs: https://coil.trade/#how - Pricing: https://coil.trade/#pricing - FAQ: https://coil.trade/#faq
