Quant-Builder.ai is that platform for people who want to quant trade stocks for real — not stitch a screener to a spreadsheet.

Why Equities Suit This Approach Particularly Well

The instrument is not incidental. Stocks happen to be close to ideal for model-driven selection, for reasons worth spelling out.

Breadth. Thousands of names means thousands of comparable observations per day. A model needs cross-sectional variety, and equities supply it in a way that a handful of futures contracts cannot.
Rich fundamentals. Earnings, revenue, margins, growth rates and balance sheet data give a model information beyond price. Most asset classes have nothing equivalent.
Long history. Decades of daily data across many market regimes, including several genuinely different crises to test against.
Sector structure. Stocks belong to industries that move together, which is real, learnable signal rather than noise.
A natural daily cycle. The close creates a clean point to score everything and rank tomorrow. Continuously traded markets have no such boundary.

That last point quietly shapes the whole design. Nightly scoring is possible because equities stop.

The Equity-Specific Mechanics You Have to Handle

Stocks also bring particular problems, and how a platform deals with them determines whether results are trustworthy.

Splits and dividends. An unadjusted price series shows a fifty percent crash where a two-for-one split occurred. Adjustment must be handled or every technical feature is corrupted.
Delistings and survivorship. If your history only includes companies that still exist, your test quietly excludes every failure. This inflates results and is one of the most common invisible errors.
Restated fundamentals. Companies revise figures. Using the revised number in a test of an earlier date means using information nobody had.
Borrow availability. A short model is only tradeable on names your broker can actually locate.
Liquidity. A beautiful backtest on microcaps you cannot fill at size is not an edge.

What Sits Behind the Stock Universe Here

3,000+ US stocks with 600+ features each, updated nightly after the close. Price and volume history, technical indicators, fundamentals including earnings, revenue growth and margins, and sector and macro context such as sector valuation medians and yields. Dated point-in-time, so a model tested on a date sees only what was published by then.

Long and short books are both supported, with independent sizing and exits, subject to what your broker permits on your account.

Where a Stock Platform Is the Wrong Tool

If you trade options, futures, forex or crypto, this architecture does not transfer. Options require modelling volatility surfaces and expiry. Futures involve contract rolls. Crypto trades continuously, so there is no close to score against. Those are different problems and want different tools, and it is more useful to say so than to imply universal coverage.

Frequently Asked Questions

Which stocks are covered?

3,000+ US-listed stocks, with 600+ features per name, refreshed nightly.

Are splits and dividends handled?

Yes. Unadjusted series would corrupt every technical feature, so adjustment is part of the data layer rather than something you manage.

Does the history include companies that no longer exist?

It has to. Testing only on survivors excludes every failure and inflates results, which is one of the most common hidden errors in retail backtesting.

Can I trade short?

Yes, subject to your broker locating the borrow. Long and short books carry independent sizing and exit configuration.

Can I use it for options or crypto?

No. It is built for equities on a multi-day horizon. Derivatives and continuously traded markets need tools designed for them.

What does it cost?

The demo at /learn is free. Paid plans start at $25/month.
