get_helio_lon(t)
Computes Neptune's heliocentric ecliptic longitude using VSOP87 theory.
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Heliocentric ecliptic longitude in degrees, normalized to range [0, 360).
get_helio_lat(t)
Computes Neptune's heliocentric ecliptic latitude using VSOP87 theory.
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Heliocentric ecliptic latitude in radians, range approximately . Note: Returns radians, not degrees.
get_helio_radius(t)
Computes Neptune's heliocentric radius (distance from Sun) using VSOP87 theory.
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Heliocentric radius in astronomical units (AU). Typical range is 29.81-30.33 AU.
get_geo_speed(t)
Computes Neptune's geocentric longitude speed (rate of change over time).
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Geocentric longitude speed in degrees per day. Negative values indicate retrograde motion (apparent backward movement).
get_geo_lon(t)
Computes Neptune's geocentric ecliptic longitude (as seen from Earth).
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Geocentric ecliptic longitude in degrees, normalized to range [0, 360).
get_geo_ecl_lat(t)
Computes Neptune's geocentric ecliptic latitude (as seen from Earth).
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Geocentric ecliptic latitude in degrees, range approximately .
get_geo_decl(t)
Computes Neptune's geocentric equatorial declination (as seen from Earth).
Parameters:
t (float) : (float) Julian millennia from J2000.0 (use core.get_julian_millennia(time)).
Returns: (float) Geocentric equatorial declination in degrees, range where positive is north.
Neptune
Financial Astrology Neptune LongitudeNeptune energy influence the charity, confusion, imagination, waste, crime, intuition, occult, scandal, illusion and dreams. It rules the industries related to chemicals, gas and oil, drugs and alcoholic beverages, scams, non profit organisations, spirituality. The last decade Neptune have been traveling through Piscis sign which caused humanity to have an illusion that economical growth don't have limits, as consequence we saw US indexes growth toward new all time highs. However, Neptune is close to leave Piscis, in 7 more degrees as per July 2021 and new cycle is going to start. It will be interesting to see what happens as Neptune moves into Aries sign.
This longitude indicator show a zodiac signs horizontal line boundaries that identify the start of the sign marked in the corresponding horizontal line label in the Y axis, this simplify the analysis of a planet effect within specific zodiac sign.
Note: The Neptune longitude indicator is based on an ephemeris array that covers years 2010 to 2030, prior or after this years the data is not available, this daily ephemeris are based on UTC time so in order to align properly with the price bars times you should set UTC as your chart timezone.
Financial Astrology Neptune DeclinationWe don't know much about the impact of Neptune declination in the financial markets but if we infer the effect of Neptune traveling toward the zero declination we can assume that the effects of illusion, inflation, scams and economic bubble could growth during the next decade giving raise to the super bubble of the blockchain industry. Only future data will give us a hint of interpretation of Neptune declination cycles, perhaps in a decade, PineScript and web clients have evolved enough so we can load 100 years of declination data to analyse the behaviour in major US indexes that provide enough years of data for a more deep study.
Note: The Neptune declination indicator is based on an ephemeris array that covers years 2010 to 2030, prior or after this years the speed is not available, this daily ephemeris are based on UTC time so in order to align properly with the price bars times you should set UTC as your chart timezone.
Financial Astrology Neptune SpeedNeptune retrograde and stationary phases indicates periods of delusion, on that moments the traders optimism bubble is burst, as consequence, we can see that most of this retrograde speed phase periods correlates with BTCUSD price correction or consolidation periods. Is very clear to see in the chart that only once, the Neptune retrogradation occurrence in September 2020, resulted in price growth. Therefore, periods of price growth and optimism are more likely when Neptune is direct.
Note: The Neptune speed indicator is based on an ephemeris array that covers years 2010 to 2030, prior or after this years the speed is not available, this daily ephemeris are based on UTC time so in order to align properly with the price bars times you should set UTC as your chart timezone.
