Lunar Cycle Timing Engine
Lunar Cycle focuses on the moon phase rhythm requested for trading behavior: post-new-moon windows favor buying, full-moon windows favor selling or no-buy caution, and the days between are translated into gradual portfolio nudges.
How Lunar Cycle Works
The model calculates the current lunar phase and maps it into a repeatable timing curve. Immediately after a new moon, buy pressure can rise. As the cycle approaches the full moon, buy pressure fades and sell or no-buy pressure increases.
This creates the requested behavior without hardcoding a single calendar date. The model can run independently, or the Lunar Nudge toggle can adjust an existing model such as ARIMA, MLTFT, TimeGPT, or AlchemyAI.
- Moon phase angle converted into smooth buy and sell weights.
- No-buy pressure near the full moon and immediately before sell windows.
- Post-new-moon accumulation bias that decays as the phase matures.
- Separate model and nudge modes for controlled experimentation.
Measure Phase
Calculate the angle between sun and moon to locate the cycle window.
Open Buy Window
Increase buy eligibility after the new moon while the accumulation curve is strongest.
Prepare Caution
Reduce buy appetite as the full moon approaches and sell pressure becomes dominant.
Respect Rules
Let portfolio risk, target delta, and holding safety decide whether any action is allowed.
Cycle Formula
Lunar Cycle is deliberately transparent. It starts with phase geometry and turns that into timing weights that can be reviewed, tuned, and backtested.
Where Lunar Cycle Fits
- Simple, visible timing model with predictable buy and sell windows.
- Works as both a standalone engine and a portfolio-level nudge.
- Easy to backtest against daily and intraday market windows.
- Moon phase timing is a supplemental signal, not a price forecast by itself.
- Cycle rules need market validation before strong sizing decisions.
- Full-moon sell pressure must still pass holding and profit guardrails.
Lunar Cycle is designed for clear timing experiments: new moon accumulation, full moon caution, and conservative behavior everywhere safety rules disagree.
