Scan the market, analyze institutional flow and AI signals, and test ideas against historical data—all in one research workspace with specialist tools. Start free.
Move from discovery to a chart, historical context, and alerts without rebuilding the same idea across different apps.
Scan the market, compare clear signals, and open a company profile in your language before you spend time on the chart.
Work with 73 indicators, 128 drawings, and Fusion, Gamma, and Dark Pool context beside the price action.
Check a Fusion signal against transparent historical results and review its drivers before deciding whether the setup deserves risk.
Create alerts on the chart, control repeats, and use seasonality and relative rotation to monitor what could change next.
Use the core workspace on its own, or add the research methods that fit your process.
Three independent disciplines converge into a single, actionable trading signal.
Each discipline independently scores the market, then our algorithm fuses them into one clear signal.
What the platform actually runs on — sources, coverage and depth you can verify.
S&P 500, Nasdaq and most US stocks, with 40+ years of historical data behind every backtest and seasonality map.
Dark pool prints from the FINRA TRF via Databento (previous session, T-1). Options flow ≥15 minutes delayed — we never dress delayed data up as real-time.
The Fusion Score ships with its key drivers ranked, and backtests replay day by day. No black boxes, no unexplained signals.
The Gann and astrology research suites — planetary lines, eclipses, mass pressure — exist nowhere else in modern charting.
astrostock is an analysis platform, not investment advice. Past performance is not indicative of future results.
Professional charting is free to start. Modules and institutional data unlock with Basic and Pro.
