It's said by financial astrologers that Moon in extreme declinations above or below 22, tends to produce more extreme effects of the Moon energy effects. My friend Peter advised that extreme declinations are very intense energy points and when the extreme is reached a reversal effect is expected. We are not quite sure if this rule is valid so this indicator is to validate the this empirical observations.
Note: The Moon declination indicator is based on an ephemeris array that covers years 2010 to 2030, prior or after this years the declination 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 reference timezone.
