W.D. Gann's toolkit, rebuilt for modern markets — drawn directly on your charts.
30 planetary-event panels and birth charts on your chart — each explained by AI in plain English.
Automatically spots harmonic (Gartley) setups and maps the entry, stop and targets — from detection to exit.
Trading geometry on your chart — square-root price levels, time-target angles, and a planet-driven trend line.
Reads the market's rhythm — a band marks the active up or down cycle, and five tools help time entries inside it.
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.
