INVITE-ONLY SCRIPT
Advance Bradley Siderograph: [BlueprintResearch]
🔭Advanced Bradley Siderograph
What it is
A research indicator that computes Bradley’s terms with a private planetary ephemeris, then projects the curves forward on your chart. The ephemeris is my own library, built from scratch, with arc-second targets across modeled planets. The libraries supports both geocentric and heliocentric calculations; this model uses geocentric only. In addition to the core Bradley line, the script plots a derived rate-of-change (ROC) curve to surface acceleration, slowing, and zero crossings.
How it works
The indicator evaluates geocentric planetary relationships for each bar using my ephemeris, applies Bradley’s long-term, mid-term, and declination components, and combines them into a sidereal potential line. Aspect influence is controlled by an orb setting and component weights. Future projections are deterministic: the script computes planetary positions for bars ahead and carries the same component math into the forward window so you can see the curve beyond the last bar. The ROC curve is derived directly from the projected and historical Bradley line.
Key features
• Private planetary ephemeris with local computation and no network calls
• Future projections for all curves up to 500 bars ahead
• Rate-of-change line for acceleration, slowdowns, and inflection risk
• Component controls for long-term, mid-term, and declination with independent visibility and weights
• Display controls for colors, opacity, smoothing, and label size
Inputs
• Aspect orb (± degrees): 0 to 15
• Look-ahead bars: up to 500
• Component multipliers for long-term and ROC scaling
• Visibility toggles for sidereal potential, long-term, mid-term, declination, and ROC
• Text size: Auto, Tiny, Small, Normal, Large
Interpretation notes
This is a contextual barometer for planning and study. It does not generate trade signals. Combine the Bradley line and ROC with your own forecasting frameworks for timing and risk management.
Originality and provenance
This invite-only script runs on a planetary ephemeris library I built from the ground up. No portion of TradingView’s open-source Astrolib is used. There are no Astrolib functions, no imported third-party planetary libraries, and no external API calls. I can provide code-source evidence to TradingView moderators on request.
My open-source Bradley Siderograph on TradingView was released for education and backtesting and intentionally omitted forward projections. The number one user request has been to see the curve ahead. This advanced edition delivers that capability by projecting the Bradley line and components forward in time, up to 500 bars. To my knowledge, forward planetary projections of this kind are rare on the platform, and this edition was created specifically to provide that functionality while keeping the educational version separate and open.
Lineage
To my knowledge, I brought the first open-source Bradley Siderograph to TradingView since Donald A. Bradley’s 1947 work. This edition advances that effort with a private ephemeris, forward projections, and ROC.
