Astronomical calculations
Planetary positions and transits are calculated with Astronomy Engine. Natal house and angle accuracy depends on the birth time and location supplied by the user. House II does not invent missing birth data.
Market and economic context
House II uses public economic series from the Federal Reserve Economic Data service where relevant. Market context may include volatility, trend, liquidity conditions, risk appetite, and scheduled event risk. Market inputs describe conditions. They are not proof of an astrological cause.
Place and timezone data
Open-Meteo is used to resolve place names into coordinates and time zones. The resolved location is used for chart calculation.
Language models
Language models may turn already-calculated chart and market context into readable explanations. They are instructed not to invent placements, prices, returns, or certainty. Personalized generated readings are saved so the same request does not need to be generated repeatedly.
