The aim and object of every trader who enters Wall Street is to make money, yet it is a well-known fact that a large percentage of traders lose money. There are many reasons for their losses.

I expect to give rules provable and practical which will help traders to study and learn how to select the proper stocks to buy and sell with a minimum of risk.
