No Gambling - Principle of Krishna Consiousness Program

Dear Sir

Namaskar - Pranam.

I had a doubt in my mind from many days..
I follow all 4 principles and chat Hare Krishna jap daily ( I dont count as I chat whenever and wherever I get time, even when I am working)

My quesion is : I am interested in Share Market and want to do some share trading. So, is it also considered as Gambling..
Will I be breaking the rule or Unfollowing the principle (no gambling) by trading in share market..

Hare Krishna...
