About Breakout Scanner

The problem

Most stock screeners stop at the list. You configure filters, get a set of matching stocks, and then you're on your own. There's no built-in way to check whether that screen has any historical edge, no easy way to iterate on the parameters, and the filter interfaces themselves are slow to work with when you have a specific idea in mind.

Breakout Scanner was designed to close that gap. It combines AI-powered screening with integrated backtesting so that every screen can be tested against historical data before it's traded.

How it works

Breakout Scanner pulls fresh closing data daily for over 3,000 stocks across 21 exchanges (NYSE, NASDAQ, LSE, TSX, ASX, XETRA, Euronext, HKEX, and more). It runs three built-in breakout detectors on every stock:

• Ceiling breakout— price clears a long-term ceiling that held for months or longer.
• Momentum breakout— price pushes through resistance with confirming momentum indicators.
• Near-breakout watch— approaching a key level but has not broken out yet.

Beyond the built-in detectors, users can describe any strategy in plain English (“stocks above the 200-day average with relative volume over 2x, near 52-week highs”) and the AI will generate a structured screener using SMAs, EMAs, volume ratios, and price levels. These custom screeners can be saved, modified, and backtested at any time.

Integrated backtesting

The backtest lab runs any screener configuration against historical OHLCV data and reports what happened after each signal: total signal count, win rate, average return, median return, and the P10/P90 range across multiple time horizons (5-day, 10-day, 20-day, 60-day).

Backtested results are hypothetical and do not account for slippage, commissions, or market impact. They are useful for evaluating whether a pattern has shown a historical edge, but should not be treated as a guarantee of future results.
