range
Closed beta · Q3 2026

Most backtests
lie.
Yours
shouldn't.

Range is the research bench for serious day traders. 10 years of survivorship-bias-free US equity data. Realistic fill simulation. Walk-forward and probabilistic Sharpe scoring by default — so you ship strategies that survive contact with the market, not curve-fits that look pretty in TradingView.

The trouble with retail backtests

Your backtest is lying to you in at least three specific ways.

Every retail platform — TradingView, the marketplaces, the YouTube notebooks — ships with the same hidden defects. The strategies look profitable because the test was rigged. Not on purpose. By default.

01 — UNIVERSE

Survivorship bias

"Today's Russell 3000" excludes every busted ticker that delisted. Your ORB backtest never sees the names that collapsed at 9:32 a.m. — only the survivors. Real expected returns are significantly lower than what most tools show.

∴ Range trains on 16,000 tickers including 7,000+ delisted.
02 — EXECUTION

Fill fantasy

Most platforms fill at the bar close. Day-trading breakouts move before the close. Skip slippage on a 1.5% breakout and a losing system can look profitable. Several major scanners openly admit they ignore the spread.

∴ Range models fill ambiguity and per-tier slippage.
03 — STATISTICS

The overfitting trap

Tweak 12 parameters across 5 years. You'll find a "winner" by chance alone. Without walk-forward, Monte Carlo, or a probabilistic Sharpe ratio you're not finding edges — you're finding noise that flatters your priors.

∴ Range refuses to ship a backtest without robustness.

Built for the way day-trading actually works.

i.

No code. Real rigor.

Configure entries, exits, filters, sizing, and execution rules through a form-first builder. Behind the glass: an event-driven engine with realistic spread, queue position, and halt handling. The first no-code platform that doesn't quietly cheat.

ii.

A score that calls bullshit.

Every backtest ships with a Robustness Score: walk-forward out-of-sample performance, probabilistic Sharpe ratio, parameter heatmaps, regime breakdowns, Monte Carlo simulations. Strategies below 60 carry a warning. Below 40, a refusal.

iii.

Published-paper templates.

Reproduce strategies from real research — opening-range-breakout variants, gap-and-go studies, VWAP-reclaim setups — in one click. Compare your variants against the published baseline. Build on academic foundations instead of YouTube hot takes.

Built for three kinds of people

If you've ever optimized a strategy for six weeks and never traded it live — this is for you.

01 · Semi-pro

The systematic day-trader

You've outgrown Pine. You want walk-forward, multi-symbol portfolios, and 10-year universe — without writing a backtester from scratch in Python.

02 · Creators

The trading educator

Your audience deserves backtests that hold up under scrutiny. Range exports compliance-aware reports with hypothetical-performance disclosures by default.

03 · Prep

The prop-firm candidate

Before you risk $500 on another evaluation, validate your strategy against 10 years of US equities — and find out whether it survives a 2022-style regime.

Common questions

Range is not magic.
Here's what it actually is.

Will Range make me a profitable trader?

No — and we won't pretend otherwise. Multiple academic studies (Barber & Odean, Chague et al., FINRA 2020) put the real day-trader success rate well under 5%. Range will not change those base rates. What Range can do is dramatically shorten the time between "I have an idea" and "I know whether it survives serious statistical testing." If a strategy doesn't pass Range's robustness checks, it almost certainly won't make you money live. That alone is worth the subscription.

Is this another AI-strategy generator?

No. Range refuses to sell "AI-generated alpha." We do use language models for plain-English explanations of your backtest results and for natural-language editing of conditions — but the core engine is a deterministic event-driven simulator running on clean historical data. The differentiation is statistical rigor, not magical signals.

Do I need to know how to code?

Not at all. Range is form-first. You configure rules through dropdowns, sliders, and conditional blocks. There's an "advanced" mode that exposes a logic tree for multi-condition entries, but you'll never touch a code editor.

Will I be able to trade live from Range?

Not in v1. We're shipping the research bench first. Paper-trading is on the roadmap for Q4 2026.

What markets does Range cover?

US equities only, with 10 years of delisted-aware history on 1-minute bars. Crypto, futures, options, forex are on the roadmap for Q4 2026.

Who's behind Range?

Range is currently a solo project run by a software engineer with a background in systematic trading research. Building in public — beta members get the founder's direct line during the program.
