Workflow Integration

Designed to fit seamlessly into your existing local development loop.

1. Run Backtest

Execute your strategy locally using the LEAN CLI. Output generates a standard JSON result.

2. Auto-Ingest

LocalAlpha watches your output folder. As soon as the file appears, the dashboard updates.

3. Deep Dive

Recalculate metrics, drill into trades, and verify log events without leaving your desktop.

Institutional-Grade Analytics

Everything you need to audit your strategy's performance.

100% Local & Private

Your strategy data never leaves your machine. LocalAlpha runs entirely offline, making it safe for proprietary institutional algorithms. No telemetry, no "cloud sync", no leaks.

Instant Ingestion

Drag & drop `result.json` or use Auto-Watch to sync instantly.

Advanced Metrics

Local recalculation of Sharpe, Sortino, Calmar, and PSR.

Trade X-Ray

Drill down into every execution. Analyze Maximum Adverse Excursion (MAE) and MFE scatter plots to optimize your stop-losses and take-profit levels with surgical precision.

Reality Check

Reconcile your backtests with live trading results. Detect slippage, latency, and execution errors by fuzzy-matching trades across two result files.

Log Explorer

Virtualized, regex-powered search for gigabyte-sized log files.

Optimization

Visualize parameter stability with interactive heatmaps to avoid overfitting.

Portfolio Intelligence

The "Fund Manager" view. Analyze correlations, sector exposure, and rolling beta across multiple strategies. Perform professional-grade attribution analysis locally.

Why upgrade from the CLI?

You wouldn't trade without charts. Why backtest without them?

Frequently Asked Questions

Is my strategy code or data ever sent to a server?
No. LocalAlpha is a strictly local desktop application. It reads files from your hard drive and processes them in memory. No backtest data or strategy code is ever transmitted.
Does this replace the LEAN CLI?
No, it complements it. You continue to run backtests with LEAN CLI as usual. LocalAlpha acts as the visualization layer for the output files.
What OS platforms are supported?
We support macOS (Apple Silicon & Intel), Windows 10/11, and Linux (Ubuntu/Debian based).
Can I use this for live trading?
Yes. The Live Monitor feature allows you to tail a live deployment's result file in real-time, providing a dashboard for your running algorithms.
