As on 1st April 2015 Sun, Mercury & Ketu in Pisces, Venus & Mars in Aries, Jupiter in Cancer, Moon in Leo, Rahu in Virgo and Saturn in Scorpio. Planetary transits in April: 6th Venus -> Taurus, 12th Mercury -> Aries, 15th Sun -> Aries, and 27th Mercury -> Taurus.
The planetary positions given above are at the time of Sunrise in India(Kerala) and Moon's conjunction effects on markets may be seen in countries (Asia / Europe / US) where trading take places at the time of conjunction(0°). When the angular difference between the Moon and the planet is more than 5 degrees or conjunction occurs in Rasis(constellations) other than the Sun's Rasi, there may be a delay up to 24 hours in the conjuntion effect according to their positions (note: expect only eighty percent success in assumptions based on Moon's conjunction with Mars, Venus and Jupiter as some other astro factors may also influence the market). Since Jupiter is in retrograde from 8th December 2014 to 8th April 2015 the market may be highly volatile. There is a lunar eclipse in the evening of 4th. The solar eclipse occured on 20th March was not visible in India. As Moon conjuncts with Mars and Venus on 19th and 21st respectively Nifty may move downwards on 20th to 22nd.
