Your AI trades it. Coil teaches it how.

Coil is a rules-based, long-only stock scanner that finds market leaders at real pullbacks, with its record published every session. The Coil Scanner scores every name in the Equities book (S&P 500, Nasdaq-100, and a Macro book of bonds, income, metals, commodities — 600+ names) — opportunity, entry-window, hold-conviction, leadership, sector-rotation phase, market posture — re-scored every ~5 minutes through the US market day, and maps leaders to leveraged vehicles (NVDA → NVDL, QQQ → TQQQ). You read the board and place your own orders. Coil Live serves the engine-grade board to your own AI agent over MCP, with the served trading discipline: buy the highest-conviction leaders when they're ready, size by conviction, exit on a ladder with trailing stops, and hold cash when the pool is thin. Your agent places the orders at your own broker; Coil never holds your account, your keys, or your money.

Coil Live is built for Claude Code, and any capable coding agent that speaks MCP works — Cursor, Codex CLI, Gemini CLI, or an equivalent. You add mcp.coil.trade/mcp to your agent with the license key you get at checkout. Your own agent places the orders through a broker connector — built for Robinhood, and any broker with an equivalent MCP works. Your agent is billed by its provider, never by us, and we never see your broker account. The Coil Scanner needs no agent and no broker connection: you read the board in your browser.

With the Scanner, you decide when to look and what to place. With Coil Live, your agent does the watching: the served rules start it in dry-run — test orders printed, none placed — until you say otherwise. Once you do, it reads the feed and follows the served rules at your broker, with no screen-watching required. You're never locked out: read every rule, and say “stop” and your agent pulls the plug (stopping never sells what you hold). If the feed stops, the served rules tell your agent to open nothing new and keep managing exits. Rules fire without emotion — they reduce big single-day damage, they don't remove risk. Coil accelerates its best ideas with leveraged ETFs, and those can move fast and lose value rapidly, including total loss.

Coil Scanner is the scored board of 600+ names, read in your browser: opportunity, entry-window, hold-conviction, leadership, sector rotation and market posture, with leveraged-vehicle mapping, re-scored every ~5 minutes through the US market day. Scores and states only, no stop or target prices. Coil Live includes everything in Scanner, plus the engine-grade board served to your agent over MCP — structural stops, targets, conviction and lanes per name — with every live tool at unlimited calls and the served, versioned trading discipline. Both are impersonal research publications, identical for every subscriber, and you can cancel anytime. There's a free preview of the board before you pay.

Because leadership rotates. Every cycle has leaders — semiconductors led in 2024, but before and after that the baton passed to other groups. A one-sector engine is right only while its sector leads and dead weight the rest of the time. Coil scores the whole market — the Equities book of S&P 500, Nasdaq-100, and Macro names — and follows leadership wherever it goes, buying names coiled at real support when they're ready and standing aside from the falling knives and the overbought chasers. The name still fits: Coil looks for leaders coiled at support and strikes when they're ready; it just does it across the whole market now.

Very. Coil accelerates its highest-conviction ideas with 2× and 3× leveraged ETFs, so a ~10% move in the underlying is roughly a ~20–30% move in the vehicle, before gaps and slippage. Leveraged ETFs also decay on multi-day holds because they track daily moves, and a position can gap through the hard stop before the open (a stop can't fill in a gap). The engine caps exposure and the circuit-breaker ladder reduces single-day damage, but neither removes risk. You can lose money rapidly, including total loss.

The engine only buys when the pool has real leaders that are ready — coiled at support, not falling and not overbought. When the market posture turns defensive it tightens entries and rotates toward the Macro book (bonds, income, metals); when nothing qualifies it holds cash, and on Robinhood Gold that idle cash earns the broker's cash sweep, ~3.35% APY (variable) as of Sept 2026 — the broker's yield, not Coil's, and not guaranteed or risk-free. The research backbone is honest about when the edge shows up: through end-2025 the ranking brain ran about even with SPY at roughly a third less drawdown, and it pulled ahead in leadership regimes (2025 and 2026). Those are research figures, not a prediction.

Coil's trading rules are for equities and do not trade crypto. The board, yes as a read: since July 15, 2026 the Coil Scanner board pairs the Equities book with the Crypto book — BTC and ETH scored with long-only trend signals. The honesty rider ships with it, ugly parts first: the cold backtest does not beat buy-and-hold CAGR (59.6% vs 74.9% for a 50/50 BTC/ETH hold, 2016–2026); what it buys is smaller crashes (2022: 0.0% vs −66.0%; max drawdown −64.3% vs −87.4%) at the cost of whipsaw years (2024: −22.6% vs +74.7%). Signals tracked live since July 15 — backtest before that, not traded with real money. The full numbers, losses included.

Automatically. The board is re-scored every ~5 minutes through the US market day, so there's nothing to install or refresh. Coil Live's trading discipline is a versioned rulebook your agent reads from the feed: updates ship through on the next call, nothing to re-download. New validated versions — new scanner factors, entry windows, exits, or book coverage — are cold-validated first and announced on coil.trade.

Yes. An agent can discover Coil (there's a machine-readable manifest at /.well-known/coil.json), connect to Coil Live over MCP, and operate on a schedule. Buying the Scanner or Coil Live is ordinary web commerce: checkout is a hosted Gumroad flow — Gumroad is the merchant of record and handles receipts and license keys. There's no special agent-checkout integration; an agent with delegated card authority can complete the hosted checkout like any web checkout. And the scanner board itself is agent-purchasable natively: pay per read in USDC over the x402 protocol — no account, no card, no email (the agent endpoint). It runs on your approval and your own credentials, and you stay in control. Coil is an impersonal research publication, not investment advice, and makes no income promise.

The Scanner takes none: open the page. Coil Live takes about two minutes. Add mcp.coil.trade/mcp to your agent with the license key you get at checkout, then tell it: “call get_live_setup and follow it.” It runs in dry-run — printing test orders, placing none — until you say otherwise. Going live is always a separate, deliberate step.

The ranking brain — the leadership scoring the whole system is built on — was replayed on a survivorship-free research backbone: point-in-time S&P 500 membership including delisted names (so failures like FRC and SIVB are in the data, not quietly dropped), next-open fills, and modeled trading costs, from 2017 through 2026 H1. That's research that validates the brain, not a live account record, and it has self-tuning degrees of freedom, so treat the figures as evidence, not proof. The live engine is newly running; live and forward results, accumulated on small size over time, matter more than any backtest — which is why the live record is published every session next to SPY and QQQ.

Coil trades actively — many entries and exits a year across a rotating set of names — so realized gains are largely short-term (taxed as ordinary income), and active trading can create wash-sale complications that defer losses. None of that is tax advice — talk to a tax professional about your own situation before trading real money. Coil reports nothing on your behalf.

No. Coil is an impersonal research publication: you, or your own agent, place every order at your own broker with your own capital. It is not investment advice, not a managed fund, and not a guarantee of profit. Coil holds no funds and executes nothing on anyone's behalf. Trading leveraged ETFs carries substantial risk of loss, including total loss. The performance figures on this page are a survivorship-free research backtest that validates the ranking brain — not a record of anyone's client or account returns, and not a prediction.
