Who Coil is for
Coil is opinionated on purpose. Here are the people it fits — and, honestly, the people it does not.
Most trading products try to be for everyone, which is usually a sign they're for no one. Coil is opinionated instead. It does one thing well: it scans the whole Equities book (S&P 500, Nasdaq-100, and a Macro book of bonds, income, gold, and commodities — ~560 names), scores every name, and runs a long-only engine that buys the actual leaders at real entries, on your own machine, through your own broker, with your own capital. That opinion is the product, and it means Coil is a good fit for some people and a genuinely poor fit for others.
Below are the four people it's built for, and then the honest list of who should walk away. None of this is investment advice, and nothing here is a recommendation to buy, sell, or hold any security.
1. The hands-off swing trader
You believe in owning strength — the market's leaders, wherever they are this quarter — but you have a job, a life, and no appetite for staring at charts all day. You don't want to miss the moves, and you don't trust yourself to size and time them by hand without fear or greed getting a vote.
This is the core fit. Coil watches the whole board for you on a schedule and acts by rule, not by mood. Its entries buy disciplined weakness in confirmed uptrends — a leader that has pulled back to support and is READY — and it refuses the two entries that quietly lose money: it won't chase an extended name pinned at its highs, and it won't catch a falling knife. Its exits are deterministic: a trailing stop on every position, a scale-out ladder at structural targets, and cash when nothing qualifies. It even adapts sizing to your book without you touching anything — at each close a local pass leans position sizing toward whatever has been working in your own closed trades, size-only and inside hard clamps. The point isn't to outsmart you; it's to remove the screen from the equation. If you want to understand the rhythm before you commit, the how it works page walks through every layer.
2. The rotation-chaser who's always late
You know leadership rotates — semis lead, then it's financials, then energy, then back to megacap tech — and you always seem to arrive a beat late: buying the theme after it's run, holding it a month too long, and rotating out right before it works again. The pattern is exhausting, and it's expensive.
This is exactly the miss Coil is built to close. The scanner scores sector phase and leadership across the entire universe every cycle, so the book fills with whatever is actually leading now — and empties when that leadership fades. It buys the turn, not the top: a leader at a real entry, not a theme after the crowd has piled in. When leadership leaves equities entirely, the Macro book rotates the money defensively into bonds, income, or gold rather than fighting the tape. You stop guessing the rotation by feel and let a scored board do it. The glossary defines leader rotation, entry window, and market posture if the terms are new.
3. The AI tinkerer
You already run Claude with MCP tools. You've wired up a scheduled agent or two, you understand the plumbing, and you could roll your own trading loop — but you'd rather not start from a blank file and a year of debugging your own scanner and backtest harness.
Coil is built for exactly your stack: an AI agent (built for Claude / Claude Code, on a schedule you control) operates the engine, and the broker connector is built for Robinhood but works with any equivalent broker MCP. What you're buying isn't the agent — you already have that — it's a validated, market-wide scanner and a long-only engine, with the research backtest harness and a safety self-test suite in the packet, all runnable on your own machine. Point your agent at the folder and the dashboard opens with live scores within minutes. And because you like to see the machinery: every sizing tilt the local learning pass makes — size-only, split by book and buy-score tier, hard-clamped — is written to a readable audit trail (optimization_log.json) you can inspect. Start with the Claude + Robinhood agentic trading guide, or read up on whether Claude can trade stocks at all.
4. The risk-conscious skeptic
You've been pitched too many bots. You don't want a screenshot of a green equity curve; you want to read the actual rules, see the benchmark next to every number, and know where the strategy is weak before you risk a dollar.
This is the person Coil was secretly designed to win over. The full v4 system ships to you — the scanner, the dashboard, the long-only engine, the safety spine, and the research backtest harness. The numbers come with SPY next to every one and the honest rider up front: on point-in-time index membership (delisted names included, so no survivorship bias), with next-open fills and costs modeled, the leadership-rotation backbone compounded +638% from 2017 through the first half of 2026 versus SPY's +282%, at a shallower worst drawdown (−23% vs −32%) and positive in 9 of 10 years (worst −1%, 2018). And the part most sellers bury: through the end of 2025 it ran roughly even with SPY at about one-third less drawdown — the outperformance concentrates in leadership regimes (2025 +51%, 2026 H1 +86%). These are research figures, not live results. And the only thing that adapts on your machine is position sizing: a local pass that leans size toward what has been working in your own closed trades, hard-clamped to roughly 0.55×–1.35× and written to a readable audit trail, never touching the entries, exits, stops, or caps. If you want to see how that self-tuning loop stays inside hard bounds rather than overfitting, read self-tuning vs static trading bots.
The caveat that applies to all four: the numbers above are a research backtest, not a promise, and the edge concentrates in leadership regimes — in flat or leaderless markets, expect roughly market returns with less pain. Coil is long-only, but where it accelerates a leader through a leveraged ETF, that ETF can lose value rapidly, including total loss of the amount committed to it. Coil's entry discipline and safety spine aim to reduce and bound damage; stops can still gap straight through a price. No use case removes that risk.
Who Coil is NOT for
The fastest way to know if Coil fits is to read who it doesn't. If you see yourself below, please don't buy it — you'll be disappointed, and we'd rather say so now.
| If you want… | Why Coil isn't it |
|---|---|
| Guaranteed or projected returns | Coil promises none, and anything that does is the thing to walk away from. Past research results do not predict future results. |
| A managed, zero-effort product | This is software you install and operate. It is not a managed account, a fund, or a service that trades for you. |
| To go short / profit from crashes | Coil is long-only by design. In a downturn it raises cash and rotates defensively — it does not short. |
| To pick your own stocks | Coil decides the book from its scores. It's a rules engine, not a discretionary tool you override name by name. |
| No setup work | Plan on a short, agent-led setup to a scheduled dry-run — OS detect, a free Alpaca data key, a first scan and dashboard — and going live is a separate, deliberately gated flow. There's no one-click version. |
To be clear about the first two rows: Coil is not investment advice, not a recommendation, not a managed account, and not a signal service. It's a one-time $29 download you keep forever — no subscription, no tiers. If you're weighing it against hosted alternatives, the Coil vs trading bots and signal services comparison lays out the trade-offs fairly.
Still not sure?
If you're somewhere between "this fits" and "this doesn't," that's a reasonable place to be — and a sign you should read more before paying anything. The leverage-decay explainer is worth your time, because if leveraged-ETF risk isn't something you're comfortable owning on the engine's most aggressive positions, size accordingly. The FAQ answers the practical questions about setup, refunds, and updates.
Coil is opinionated, honest, and not for everyone. If you're one of the four people above and you've read the risk, the pricing page has the $29 download.
If one of these is you, own the engine for $29
Download the full market-wide scanner, dashboard, and long-only engine once and keep it. You hold the keys, the capital, and the risk.
See pricing — $29Coil 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. All performance figures are research backtests — point-in-time and survivorship-free, not live or client returns; past performance does not predict future results.
