The AI trading system you download and own.
Scan, decide, place, manage — the whole loop, run by your own AI agent, by rule, on your own brokerage. You watch a dashboard for two minutes a day; it does the rest. Long-only, built for Claude Code and Robinhood's agentic accounts.
Coil Engine is a long-only agentic trading system you buy once and run yourself: a local scanner that scores ~560 names across the S&P 500, Nasdaq-100, and a Macro book, a dashboard, and a rule-based engine your own AI agent operates against your own brokerage. It ships with live trading OFF, and your keys never leave your machine.
Who does what, in order
Every market morning, the same four steps run in the same order. No mood, no headlines, no revenge trades at 2am — the loop is the product.
1 · Scan
It scores the Equities book — ~560 names across the S&P 500, the Nasdaq-100, and a Macro book — for opportunity, entry state, and hold strength. This is the exact board Coil Scanner subscribers read; the engine and the board come from the same run.
2 · Decide
Regime verdicts gate everything top-down: index, then sectors, then names. When the layers above say stand down, it stands down. Refusing bad trades is most of the job — cash is a position.
3 · Place
This is the step Coil can't do itself — it has no hands and no broker login. The engine writes the order; your agent places it at your brokerage. Sized by rule, with a structural stop (roughly 4–14%, set by the chart, not by hope) attached at the moment of entry.
4 · Manage
Holds are re-scored daily. Winners get room to run, laggards get cut, late-trend names get tighter risk, and a drawdown breaker can halt the whole book.
The real product is your time back
Watching the tape is a job. The bot's pitch is not that it knows the future — nothing does — it's that it executes a disciplined, fully-written-down process every single day without you standing over it. Your oversight shrinks to reading a dashboard: what it holds, why it holds it, and what it plans to do next. Every decision traces back to a number on the board you can see.
And because it's software, the discipline is structural. It cannot chase a green candle, average down out of stubbornness, or freeze at a stop. The rules you read on how it works are the rules it runs — there is no other layer.
You stay in control
Live trading ships OFF
Out of the box it observes and plans. You flip live trading on deliberately — and telling your agent “stop” flips it back off at any time. Stopping places nothing and sells nothing: what you hold stays yours to manage.
No deposit, no vault, no withdraw button
It runs on your computer against your own brokerage account. There is nothing to fund and nowhere to send money — Coil has no vault, hosts nothing, and contains no code that can move funds. Credentials never leave your machine. The full architecture, with code receipts →
Hard risk rails
Structural stops on every position, reduced size anywhere leverage is used, late-trend risk tightening, and a drawdown breaker that halts the book.
One account, long-only
It trades exactly the account you point it at, long-only. No shorting, no margin games, no surprise instruments.
Pick a temperament, not a config file
Coil ships with validated strategy profiles — Paper Observer to watch, Swing Leaders to run the flagship rules — each with an honesty rider your agent reads to you before you choose. Profiles adjust temperament only; the safety rails are not knobs on any of them.
The proof, with its rider
The honesty rider, up front. The ranking brain backtests at +638% for 2017–2026 H1 vs SPY's +282% (survivorship-free research backtest, not live or client returns) — and through end-2025 it ran roughly even with SPY at about one-third less drawdown; the edge concentrates in leadership regimes. The engine itself is newly live, and we say so. The year-by-year table shows the years it lost to SPY, next to the years it won, and the live record shows every settled session since the engine went live — wins and losses, against SPY.
Your copy will not trade like ours — here is why
You are buying a written-down process and the software that executes it, not a copy of our results. Our live record is one real account — ours, our capital — running this engine and published every session including the losing ones. It is evidence that the discipline holds up when it is followed. It is not a number your install inherits, and the honest reason is that almost nothing about your run is identical to ours.
Three of these are about the copy you run; three are about your account:
So take the record for what it proves: that the stop derivation, the entry guards, the sizing precedence and the exits-first cycle add up to something that has been run on real money and shown its work every session. That process is what you are buying, in source you can read, audit and rewrite. The number at the end of your own year is yours.
What's in the download
One purchase, three parts, all running locally: the scanner (the scoring brain), the dashboard (the same board you can try in the demo), and the engine (the rule layer your agent operates). Plus the setup guide that walks you from unzip to first paper session.
What you need: Claude Code (the AI agent it's built for), a free Alpaca data key for market data, and — for live trading — a Robinhood account with agentic access via MCP. If you can follow a README, you can run it; the setup guide covers the whole path.
Rather read the board yourself? Coil Scanner is the same brain, hosted — the full board in your browser, re-scored every ~5 minutes through the market day, $12/mo, no software to run. Same scores; you make the calls.

Will it make me money?
Unknowable, and anyone who answers differently is selling something. Markets can lose money; leveraged ETFs (used at reduced size) can lose value rapidly, including total loss. What it will do is execute a written-down, long-only process with discipline you can audit.
Will it match the results you publish?
No. Your copy scores from your own market-data key, on your own schedule, with rules you are free to rewrite, and it sizes and fills against your account. What transfers is the process, not the profit and loss — the full list of what makes them diverge.
Is this investment advice?
No. It's self-operated software plus impersonal research — the same board for everyone, no account-aware recommendations. Your agent, your broker, your capital, your decisions.
Do I need to be a programmer?
No — you need Claude Code installed and the patience to follow the setup guide. The agent does the operating; you do the deciding about whether it should.
Why one-time, not a subscription?
Because you're buying software, not renting a signal — you own the download and keep every update. Here's the case for one-time-purchase trading bots over monthly fees, and how Coil stacks up against the field in our honest review of AI trading bots.
Can I see it before I buy?
Yes — the demo is the actual dashboard with frozen data, and how it works is the full rule set. Nothing is behind the purchase except the software itself.
Read exactly how it decides
The full rule set — regime gates, entry lanes, stops, sizing, the drawdown breaker — is public. Read it before you spend a dollar.
How it works →Coil is software you install and run yourself, with your own brokerage credentials and capital. It is long-only and not investment advice, not a managed account, and not a signal service. Leveraged ETFs, where the engine uses them, can lose value rapidly, including total loss. Backtested figures on this page are research backtests — point-in-time and survivorship-free, not live or client returns. The live record is real trading in one Coil-operated account with our own capital, published win or lose; it is not a projection of your account. Past performance does not predict future results.
