Everything you need to know to get value from the platform on day one — from alerts to the API.
Register at /register with an email and password. No credit card required for the Free plan. After registration, you will be directed to the dashboard.
From the dashboard, click 'Add Stock' and search by ticker symbol or company name. Free plan supports up to 3 tickers. Pro+ is unlimited.
Navigate to /alerts and click 'New Alert'. Select a ticker, condition type (Price / RSI / Volume / MA Cross), and threshold. The engine checks every data tick and notifies you by email when triggered.
A daily digest is sent at 08:30 EST, Monday through Friday, to all plans. It includes overnight moves, RSI levels, upcoming earnings, and the macro snapshot for every ticker on your watchlist.
Triggers when a ticker crosses a specific dollar value — either above or below. Set absolute targets or percentage-based distance from current price.
Triggers when RSI(14) crosses a threshold on a selected interval: 1-day, 4-hour, or 1-hour. Standard overbought (>70) and oversold (<30) thresholds, or any custom value. Pro+ only.
Triggers when session volume exceeds a custom multiplier of the 20-day average. Example: 2.5x average volume is a meaningful spike in most liquid equities. Pro+ only.
Triggers on golden cross (50MA crosses above 200MA), death cross (50MA below 200MA), or when price crosses a specific moving average. Pro+ only.
Combine up to three conditions with AND or OR logic. Example: RSI < 35 AND Volume > 2x average. Requires Advanced or Master plan.
Submit any US equity ticker. The system fetches recent price action, earnings trend data, analyst revision summary, and news headlines, then processes the data with AI. Results return in approximately 8 seconds.
Momentum score (Strong / Moderate / Weak), Earnings risk score (1-10), Analyst consensus trend (Improving / Stable / Deteriorating), and a directional bias (Bull / Bear / Neutral) with a short written rationale.
AI output is a summarization tool, not a research report. It may be wrong, outdated, or miss context. Always verify with primary sources. Results are generated fresh per query — not cached. Advanced and Master plans only.

Export any screen result as CSV or JSON. Pro+ only. No throttle on export frequency.
