Coil vs StockHero
Hosted no-code trading bots on a subscription vs. an agent-native engine you own — compared on key custody, cost, and how each frames its numbers.
StockHero and Coil both automate stock trading, but they sit at opposite ends of the design space. StockHero is a hosted bot platform: you pick a preset bot or rent a strategy from its marketplace, and StockHero's cloud runs it against your linked brokerage, around the clock, with nothing installed on your side. Coil is one finished engine you download and own: an agent-native, long-only copilot that scans the whole market, scores every name, and buys leaders at real entries — running on your own machine, with your broker credentials never leaving it. Neither is "better" in the abstract; they answer different questions. This page lays out the honest trade-offs.
Coil is independent and is not affiliated with, endorsed by, or partnered with StockHero. Everything below describes StockHero from its public materials; any performance language — including win-rate figures — is their marketing, not our claim. Nothing here is investment advice or a recommendation to buy, sell, or hold any security.
What StockHero actually is
StockHero is genuinely good at what it does, and it's worth saying so plainly. It's a cloud platform of no-code stock trading bots: you deploy a preset, configure one yourself from templates, or rent a strategy other users or the platform publish in a paid marketplace, and StockHero's servers execute it in your connected brokerage account. The strengths are real:
- Approachable. Preset bots can be running in minutes, with no code and no infrastructure of your own — probably the lowest barrier to entry in this category.
- Paper trading. A simulated environment lets you watch a bot behave before it touches real capital, which is exactly the right habit.
- A strategy marketplace. Renting a bot someone else built is a fast way to start, and the marketplace shows each bot's track inside the platform.
- Hands-on support. StockHero offers white-glove onboarding, and its user reviews are strong — around 4.5/5 on Trustpilot as of July 2026.
- Multi-broker. It connects to several brokerages, including TradeStation and Alpaca.
The model is a subscription. As of July 2026 StockHero advertises tiers around Lite $49.99/month, Premium $99.99/month, and Pro $159.99/month — roughly $500–$1,600 a year depending on tier and billing (check their site; pricing can change) — and marketplace strategy rentals are priced separately on top. For someone who wants hosted, hands-off automation with presets to lean on, that's a coherent product at a defensible price.
What Coil is — and isn't
Coil is the opposite shape on purpose. It is not a bot platform. There's no fleet of bots, no marketplace, nothing to rent, and no cloud running on your behalf. It is one opinionated, finished engine that does the deciding for you. Its scanner scores every name across the S&P 500, the Nasdaq-100, and a macro book (bonds, income, gold and metals, commodities) for opportunity, entry-window (READY / SETUP / WAIT / CHASE / FALLING), hold-conviction, leadership, growth, sector-rotation phase, and overall market posture. A long-only engine then buys the leaders that score READY or SETUP at real entry windows, sizes by conviction, accelerates the strongest names with leveraged ETFs at reduced notional (e.g. NVDA→NVDL, QQQ→TQQQ), ladders out on strength under trailing stops, and raises cash when the pool is thin. You download it once, it runs on your own machine (Mac or Windows, Python 3.9+, a free Alpaca data key), and it operates through an AI agent built for Claude on a schedule you control, placing orders via a broker connector built for Robinhood (or any equivalent broker MCP). Your credentials never leave your machine, and it ships with live trading off until you deliberately arm it.
Coil's entry discipline is the point: it buys leaders at real entries and refuses the two ways people lose — it never buys FALLING names (falling knives) and never CHASEs extended names pinned at their highs. It is long-only by design; a "down" market means raising cash and rotating defensively into the macro book (bonds, gold, income), never shorting. Because the rule-set is one finished, validated thing instead of a shelf of bots, Coil ships its own research-backtest harness — the exact tool used to validate it, run point-in-time and survivorship-free — plus a safety self-test suite you can run yourself. The engine also self-tunes, but narrowly: a nightly local loop retunes position sizing (only sizing) to your own fills within hard bounds, while the validated rule-set stays frozen and fingerprinted — new strategy structure arrives only as a deliberately shipped, re-validated version you download when you want it.
The leveraged-ETF risk is real, whichever tool you choose. Coil accelerates its strongest leaders with leveraged ETFs at reduced notional — a 3x leveraged ETF triples the daily move, so a ~10% move in its index is roughly ~30% in the ETF before gaps and slippage, and leveraged ETFs decay on multi-day holds. They can lose value rapidly, including total loss of the capital you put in. No bot platform and no engine removes that. Coil's structural stops and rule-based exits aim to reduce single-day damage — they do not guarantee it, and a stop can gap straight through a price.
The comparison
| Question | StockHero | Coil |
|---|---|---|
| Core model | A platform of many bots — presets, templates, and a paid marketplace of rentable strategies | One ready engine — scans the market, scores every name, buys leaders long-only |
| Where it runs | StockHero's cloud, 24/7, nothing installed on your side | Local, on your own machine (Mac or Windows), through your own broker connector |
| Who holds broker keys | You generate broker API keys and store them with StockHero; their servers trade your account | You do; credentials stay on your machine and never touch a third-party server |
| Strategy source | Many bots of varying provenance — you pick, configure, or rent | One validated rule-set, shipped whole, with the harness used to validate it |
| Testing before capital | Paper trading inside the platform | Live trading ships OFF; research-backtest harness and safety self-tests you run yourself |
| Adapts to your fills | A bot runs its configured logic until you reconfigure or swap it | Yes — a local pass tunes sizing (only sizing) to your own closed trades, hard-clamped 0.55×–1.35× and logged |
| How performance is framed | Win rates and per-bot marketplace stats (their materials cite figures like ~90% win rates — their claim, not ours) | Full-period backtest next to SPY, with max drawdown and an unflattering rider attached |
| Cost model | Subscription — as of July 2026 roughly $49.99–$159.99/mo by tier (~$500–$1,600/yr), plus marketplace rentals; check their site | $29 one-time to own it (regular $39) — no subscription, no tiers, no recurring charge |
| Who owns the risk | You | You |
The last row is identical, and that's the honest center of any tool in this category: you are the account holder, and the leveraged-ETF total-loss risk is yours. Anything that implies otherwise is the thing to be careful of.
What a win rate does — and doesn't — tell you
StockHero's marketing leads with win rates; figures like "~90% win rate" appear in its public materials. That is their claim, not ours, and we have no basis to dispute the arithmetic behind it. The point worth making is statistical, not an accusation: a win rate, on its own, is an incomplete statistic, and it's incomplete in three specific ways.
- It says nothing about magnitudes. A strategy that takes many small wins and occasional large losses can win 90% of its trades and still lose money overall — taking profits early and holding losers longer produces exactly that shape. The number you need alongside it is the size of the average win versus the average loss.
- It has no benchmark. Winning 90% of trades means little if simply buying and holding SPY did better over the same window with zero effort. Any performance figure only becomes evidence of edge when it's placed next to what doing nothing would have earned.
- It says nothing about drawdown. Two strategies with identical win rates can have wildly different worst stretches — and the worst stretch is what decides whether a real person keeps running the system.
So when you evaluate any tool — a StockHero bot, Coil, or anything else — ask for full-period returns against a benchmark and a maximum drawdown, not a win rate. Our guide on how to read a backtest walks through the full checklist. That framing is also why Coil publishes its numbers the way it does, below — including the parts that don't flatter it.
Their cloud vs your machine
StockHero's bots run on StockHero's servers. To trade your account, you generate API keys at your brokerage and store them with StockHero — standard practice for hosted platforms, and it buys real convenience: always-on execution, no machine to keep awake, no local setup at all. The trade-off is equally plain: a third party's infrastructure holds credentials that can place trades in your account, and you're trusting their security posture as well as their code. Coil inverts it. The engine, the data key, and the broker credentials all live on your machine; you (or a scheduled Claude agent driving your broker's connector) run it on a cadence you control. That means more setup and a computer that has to be awake on schedule, but no third party sits between the strategy and your account. Different people weight that convenience-vs-custody trade differently; both positions are legitimate.
Honesty about the numbers
We won't quote StockHero's bot statistics as evidence in either direction — they're per-bot marketplace figures under their methodology, and you should read them on their site with the same checklist you'd apply to ours. For Coil, here are the figures, framed exactly as they should be. In a point-in-time research backtest (2017–2026 H1, survivorship-free with delisted names included, next-open fills, costs modeled), the leadership-rotation backbone Coil's scoring is built on compounded +638% versus SPY's +282%, with a shallower worst drawdown (−23% vs −32%) and a positive result in 9 of 10 years (worst −1%, in 2018). Read the honest rider with it: 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 or client results; the engine is newly live, and past performance does not predict future results.
| Year | Coil (research) | SPY |
|---|---|---|
| 2017 | +17% | +20% |
| 2018 | −1% | −7% |
| 2019 | +7% | +30% |
| 2020 | +22% | +19% |
| 2021 | +6% | +28% |
| 2022 | +13% | −16% |
| 2023 | +10% | +23% |
| 2024 | +12% | +27% |
| 2025 | +51% | +17% |
| 2026 H1 | +86% | +10% |
| Cumulative | +638% | +282% |
| Max drawdown | −23% | −32% |
Read it as a hypothesis, not a promise. This is a research backtest of the scoring backbone, not a live or client track record — the engine is newly live, and the rider above matters: most of the edge concentrates in leadership regimes, and it can run merely even with the index for long stretches. On thin days the engine simply raises cash rather than force a trade; any uncommitted cash earns whatever your broker's variable sweep pays (for example, Robinhood Gold quoted ~3.35% APY as of early 2026 — the broker's yield, variable, not paid by Coil, and not risk-free). Coil does not generate or promise that yield.
How to choose
If you want hosted and hands-off — no local setup, preset bots you can deploy in minutes, paper trading in the same tab, and support that walks you through it — StockHero is a strong, approachable choice, and its reviews reflect that. If you want self-custody and ownership — one validated, readable engine that scans the whole market, buys leaders only at real entries, runs on your own machine with your keys never leaving it, and costs $29 once instead of $500–$1,600 a year — that's the gap Coil fills. For adjacent comparisons, see Coil vs Composer.trade (a no-code strategy builder rather than a bot shelf), Coil vs Tickeron, and the broader Coil vs trading bots and signal services; for the agent and broker setup, the Claude + Robinhood agentic trading guide walks it through.
Neither tool can promise a profit, and neither removes the leveraged-ETF risk. They're built for different owners. When you've decided which you are, the pricing page has the $29 one-time download.
One engine, owned outright, for $29
No bots to rent and no subscription to keep it running — download the full market-wide engine once for $29 (regular $39) and keep it forever. 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.
