get_helio_lon(t)
Computes Pluto's heliocentric ecliptic longitude using Meeus truncated analytical series.
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Heliocentric ecliptic longitude in degrees, normalized to range [0, 360). Accurate within ±1 century from J2000.
get_helio_lat(t)
Computes Pluto's heliocentric ecliptic latitude using Meeus truncated analytical series.
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Heliocentric ecliptic latitude in degrees, range approximately . Accurate within ±1 century from J2000.
get_helio_radius(t)
Computes Pluto's heliocentric radius (distance from Sun) using Meeus truncated analytical series.
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Heliocentric radius in astronomical units (AU). Typical range is 29.6-49.3 AU. Accurate within ±1 century from J2000.
get_geo_lon(t)
Computes Pluto's geocentric ecliptic longitude (as seen from Earth).
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Geocentric ecliptic longitude in degrees, normalized to range [0, 360).
get_geo_ecl_lat(t)
Computes Pluto's geocentric ecliptic latitude (as seen from Earth).
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Geocentric ecliptic latitude in degrees, range approximately .
get_geo_decl(t)
Computes Pluto's geocentric equatorial declination (as seen from Earth).
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Geocentric equatorial declination in degrees, range where positive is north.
get_geo_speed(t)
Computes Pluto's geocentric longitude speed (rate of change over time).
Parameters:
t (float) : (float) Julian centuries from J2000.0 (use core.get_julian_centuries(time)).
Returns: (float) Geocentric longitude speed in degrees per day. Negative values indicate retrograde motion (apparent backward movement).
Pluto
Financial Astrology Pluto SpeedPluto retrograde and stationary phases weaken the explosive energy effect of the extreme and ungovernable actions, causing a period where traders tends to wait and analyse more before acting. We can see in BTCUSD that in most of the retrograde periods of Pluto the price was trapped (sideways) within very narrow price range consolidating the price zone reached by the aggressive moves occurring during the Pluto direct motion phase.
Note: The Pluto 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.
Financial Astrology Pluto LongitudePluto energy manifest as destruction, rebirth, death, waste, obsession, extremism, transformation, crime and underworld or unconscious. It takes in average 21 years to transit each zodiac sign so in relation to financial astrology, Pluto in Capricorn (current location) represent a generation that tends to be extremist and obsessed in materialism. This position also represent the evolution and transformation of some emergent economies that are raising the hand as the successors of the world power and the destruction of old professions with the rebirth of digital oriented jobs driven by technology (blockchain, artificial intelligence an internet). As Pluto travel towards Aquarius, this technology oriented transformation will reach the maximum momentum with a very intense technological disruption of the old tools we are accustomed to use today in favor of more powerful inventions that can take humanity toward the next level of evolution. Very likely this will be the massive adoption and popularisation of quantum computing, alternative energy sources and touristic space travels.
This indicator is not useful for short/mid term trends but as Pluto transit into different zodiac signs this will mark relevant disruptions in the humanity leadership organisation.
