Mercury-Sun angle indicator represent the geocentric longitude angular distance between Mercury and Sun with labels on the angles that indicate the astrological aspects used by financial astrologers to determine the energy trigger points. In financial astrology, Mercury rules trading, market transactions, commerce and negotiation. The Sun rules life, conscious mind, will, creative force, ego and purpose.
The greater geocentric longitude distance experienced by this planets is 28 degrees, therefore, not all the astrological aspects can be formed, the aspects that can occur are: conjuction and semi-sextile. However, the semi-sextile will never reach the exact 30 degree angle but quite close at 28 degrees, 2 degrees of orb from exact.
For any Mercury aspects indicator we recommend to use 4H resolution to locate the exact aspect culmination, this is because Mercury moves at an average geocentric speed of 1.6 degrees per day.
Due to the limited UTF (Unicode Transformation Format) support of classical astrology aspects symbols, we needed to use a custom subset to represent the aspects:
⊚ = 0 degrees angle (conjuction)
⧌ = 30 degrees angle (semi-sextile) - Note that this is never labeled due the fact that is never formed exact
Note: The Mercury-Sun longitude angle 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.
