Horai or Hora is one of the way to predict the day and also to do the right thing. There is always right timing for everything and this can be applied for stock market. I started to trade before 10 years and started with learning astrology before 5 years. Both these are arts and have to be practiced at least 60 days to make a right judgment. This book is not a quick rich scheme and it's not tough either.
In Ancient days, people used Hora for discipline in their life. Each planet has a particular hour and each day belong to a planet. There is of-course two lunar cycles ( Pournami Krishnapakshi & Amavasya Suklapakshi) The strength of these planets differ in both cycles and there is success when you keep in mind about these calculations.
It doesn't work initially for few days and when you put in to practice, you will see the result before your eyes. This is a stock picking guide and not any magical calculation from heaven. Most traders believe that buying an amazing book with exact calculations would give them fortune. But there is no fortune guide in the book store. Only the calculations and facts are provided in this book which would be an eye opener. The book is written with Indian stock market NSE with reference but it can be applied to other markets as well.
