Everything's unlocked — hunt for a strategy that beats holding, and see which ones don't.
We build the tools to hunt for a strategy that genuinely beats holding — test an idea honestly, stress it until only what holds up is left, and prove it forward before you risk a cent. Never an edge sold, never a signal to follow. The plans differ only in depth and scale; while Stratsemble is in beta, all of it is free.
Test
FreeRun any well-known strategy on any famous stock or coin, over any period — the losing years and the drawdown too, always measured against simply buying and holding. Most ideas wash out right here, and finding that out costs nothing.
Stress-test
Free · $19 unlimitedA good backtest is the easiest thing to fool yourself with. Try to disprove your own idea: is the edge real, or just curve-fit to the past? Re-run it across nearby settings and later windows — most ideas that pass the backtest don't survive this, and the rare one that does is the only kind worth taking further. (The random-timing luck check is free — no plan needed.) A free monthly allowance to taste it; unlimited is the one paid depth step (Find the One, $19).
Forward-test
Free to startA great backtest is a hypothesis, not a result. Run it forward on paper with zero hindsight — a track record that can't be curve-fit after the fact — before you risk a dollar. One forward test is free; more with a plan.
Decide — eyes open
Free to startIf you decide to act, get a mechanical alert the day your own rule fires on the close — never advice, never a trade we place. Your broker, your money; we never touch a cent, and we still don't promise you win. Three alerts are free; more with a plan.
This is the order of the discipline, not of price. Every stage starts free — even stress-testing gives you a free monthly allowance; only unlimited stress-testing needs a plan (Find the One, from $19), and it's the cheapest one. You don't climb these in order — most ideas should wash out, for free, in the first three. See the full five-stage path →
Not what you thought? Walk away — you’ve spent nothing.
- 02Test
Most “sure things” wash out right here — for free.
Most that pass the backtest should stop here.
Drifting from the sim? Better learned on paper.
Decide — or walk away. Both are free.
Illustrative — a map of the discipline, not a funnel to live trading. Most candidate ideas should wash out in the first three stages; the stages themselves are five equal places to stop, and walking away is free at every one. Not a signal to act, and not a promise that anything works.
Free for everyone in the beta
A backtest scores the past; forward-testing is about the future — run your idea forward on paper with zero hindsight, and get told the day it fires. Right now it's free for everyone in the beta. Here is exactly what that looks like — no profit claims, just the tools.
- 1. Starts flat the day you begin — it holds nothing until a bar closes after that.
- 2. Accrues forward with zero hindsight — it can only act on data it couldn't have known.
- 3. A genuine out-of-sample track record forms — the honest proof a backtest can't give, good or bad.
RSI crossed below 30 on the last daily close. A mechanical heads-up that the exact rule you set just triggered — not advice, not an order. You decide, and execute on your own broker.
No auto-trading, ever — we never touch your funds or place orders. An alert is a timestamped nudge that your own rule fired on the close; what you do next is entirely yours.
How deep you go — what you pay
The discipline is free through testing; the one paid step is unlimited stress-testing (Find the One). Forward-testing and alerts after it start free — higher volumes come with a plan, but you only ever pay once for depth.

These are the plans for when billing launches. While we're in beta it's all unlocked — no card, nothing to pay. Prices shown in USD.
Founder access
Limited-timeLock in System — the top tier — at $49/mo (normally $99), and I guarantee that price won't rise for 3 years. Cancel anytime — it's yours as long as you stay.
This isn't a tool you finish with in a month. A forward test only means something once it has enough trades behind it — often a year or more, and different for every strategy. The proof you came for is built by time actually passing: a hindsight-free track record, a growing library of your own tested ideas, alerts that keep working. The founder price locks all of that in.
Join with your email — free, no card. That reserves your founder price for launch.
Everything stays free; nothing you build gets taken away.
We email you. You start at $49/mo — your founder price, locked 3 years.
Safe to join: no charge today · leave the list anytime · 14-day money-back if you do subscribe · your price can never rise inside the 3-year guarantee.
No charge now — we'll email you when founder access opens.
Do you place trades or touch my money?
Never. We hold no funds and place no orders. Alerts are a mechanical heads-up that your own rule triggered; you decide and execute on your own broker.
Are the backtests honest?
Yes — costs and slippage on, no look-ahead, every result shown in full (losses included) and measured against buy & hold. We publish no profit claims.
What's the difference between backtest and forward-test?
A backtest scores an idea on history (easy to overfit). A forward (paper) test runs it from today with zero hindsight — the honest proof before real money.
Can I cancel or change plans?
Anytime, in-app — as easy as signing up. Every plan has a 14-day money-back guarantee: a full refund in the first 14 days, no questions and no usage catch. After that, cancelling stops future renewals and you keep access to the end of the period you paid for. Monthly caps your exposure to a single period; annual is billed a full year up front, so past the first 14 days the unused months aren't refunded — your real no-commitment trial is the free tier. This is a voluntary policy on top of, never instead of, your statutory rights: if the service is faulty or not as described, you're entitled to a remedy regardless of this window. Downgrade instead and anything over your new plan's limits is paused (never deleted) and comes back if you upgrade again.
