About this app

Turn a trading idea into rules you can test.

AI Trading Strategy Builder, also called StrategyLab, helps you describe stock strategies in plain English, explore historical results, and find stocks matching your rules.

BUILD YOUR STRATEGY
Describe your entry and exit rules. AI translates supported ideas into an editable strategy. Review the rules and assumptions before running a historical simulation.

EXPLORE HISTORICAL RESULTS
See simulated returns, largest declines, individual trades, and an equity chart. Compare results with a benchmark and inspect the trades behind the headline numbers. Configure position sizes and modeled trading costs.

RESEARCH IMPROVEMENTS
With Pro or Max, investigate winning and losing trades and test alternative rules. Research compares potential benefits and trade-offs, including consistency, losses, and reliance on a few winning stocks. It may recommend keeping the original. Research does not guarantee better future results.

FIND MATCHING STOCKS
Check supported stocks against your entry and indicator-based exit rules using the latest available daily data. Review why each stock matches. Actual positions are not tracked, so position-specific exits such as stops and profit targets are not included in these scans.

FOLLOW YOUR STRATEGIES
Pro and Max include daily entry monitoring for selected strategies and notifications when matches are available. Monitoring and usage limits apply. Max provides five times the Pro allowances.

EXPLORE DIFFERENT APPROACHES
Combine supported moving averages, RSI, momentum, candlestick conditions, and other technical indicators. Build long-only or short-only strategies using current S&P 500, Nasdaq 100, or Dow 30 constituents, or a supported custom stock list.

START FREE
Create and test strategies within the free plan's limits. Optional Pro and Max subscriptions unlock research, daily entry alerts, and higher allowances. Review current prices and plan details in the app.

UNDERSTAND THE RESULTS
Historical simulations are not actual trading performance or predictions. Results depend on dates, available data, execution assumptions, and modeled costs. Tests using current index members do not recreate historical index membership. Market data and notifications may be delayed.

StrategyLab is a research and educational tool. It does not place trades, connect to a brokerage, or guarantee investment returns. Short selling can involve substantial losses and borrowing constraints that a simulation may not fully represent.

Internet access is required for AI requests, backtests, stock scans, and monitoring. Conversations and saved strategy versions are stored on your device; cross-device synchronization is not currently available.
