Stock Strategy Builder
Design, backtest and validate rule-based trading strategies - without writing a line of code. Build, backtest and validate your own stock trading strategies — without coding, subscriptions or uploading your trading data to the cloud.
Everything a serious strategy needs, in one desktop app
From a visual rule builder to walk-forward validation, built so a profitable-looking backtest is not mistaken for a profitable strategy.
Works Offline by Default
Never connects to a broker by itself - press Login whenever you choose. Browse, build and backtest entirely offline once data is downloaded.
Resilient Bulk Downloads
Download or update historical data for an entire universe of instruments at once. One symbol failing never stops the rest of the batch.
No-Code Rule Builder
Build long/short entry and exit rules by dragging conditions and indicators - no scripting required.
29 Ready-Made Templates
Start from classic systems (Turtle Trading, Golden Cross, Ichimoku, Connors RSI(2)) or candlestick/chart-pattern reversals, then edit freely.
Multi-Tab Charts
Open several instruments side by side as independent browser-style tabs, each with its own timeframe, indicators and drawings.
44 Candlestick & Chart Patterns
Auto-detect Doji, Engulfing, Hammer, Double Top/Bottom, Head & Shoulders and more, with a hover explanation for each.
A professional research workflow, not a toy chart
