How it works

Three steps from setup to your first alert

🔗

Connect your account

Link your Alpaca brokerage account and set your watchlist. Paper trading works perfectly to start - no real money required.

📊

The scanner runs automatically

Every stock on your watchlist gets scored across 10 signals on a schedule you control. Only the strongest setups surface as alerts.

✅

You decide - with full context

Every alert lands on your dashboard with plain-English reasoning. Approve or decline. Nothing trades without your say-so unless you turn on auto-execute.

10 signals. One clear score.

Technical and fundamental analysis combined - not just price charts.

  • RSI (daily + weekly timeframe confirmation)
  • MACD crossovers (above zero only - below-zero is noise)
  • Bollinger Bands + RSI confluence
  • Volume vs 20-day average
  • Price vs 50-day and 200-day moving averages
  • 5-day momentum
  • P/E ratio, analyst consensus, revenue & earnings growth
  • Recent news keyword analysis
  • Sector ETF comparison - macro sell-off vs company-specific dip

Confluence guards built in

Alerts are suppressed automatically when:

  • ✗ RSI isn't actually oversold
  • ✗ The whole sector is falling (not company-specific)
  • ✗ Fundamentals are significantly negative
  • ✗ You already have a pending alert for that sector
  • ✗ The broad market is in a confirmed downtrend

Fewer alerts. Better alerts.

Security first

This connects to your brokerage account - we take that seriously.

🔒

API keys never exposed

Your Alpaca API keys are stored server-side and never sent to the browser.

🛡️

Brute force protection

10 failed login attempts triggers a 15-minute account lockout. Every login event is audit logged.

👤

Full data isolation

Your watchlist, alerts, and settings are completely siloed. No account can see another's data.
