I don't want to create full fledged buy sell bot because you can't be
sure who else is going to use it and it is extremely dangerous affair
so I am leaving the actually buy and sell execution part.
If someone who understands the whole process and watched my youtube video
then that person won't have any issue finding xpath for buy and sell button.
This script suppose to treat as a test project because it is not fast as 
official API key by zerodha since using Selenium it elies on a lot of Java script which loads
concurrently and there is a danger that script gets executed before the java script fully loads 
result in failed execution.
Though most l;likely it won't buy instead of sell but watch manually nevertheless to 
see execution is working.
I have run similar script in the past and it works given you add ample amount of sleep time between
each pyton call.
