Before you actually jump into do trade, first watch out news regularly. Be a watchdog in the market situations prevailing..Try to understand what is going around you..

Having said all these, now pick your sector as to which one you want to buy shares..like Metals, Pharma, Motors, FMCG etc..Then drill down to pick a list of companies that are doing well and under your budget..Now start to monitor those stocks for a few days about their momentum(buying-selling happending in a day for that stock in the market)..Then its financial statements if you are good in its numbers...

And now comes the trade portion. If you happen to see your desired stock price falling down, buy them based on your budget..In initial stages, just look out for only marginal profit..Later when you become a savvy, no need to tell how long to wait to reap your profit levels..

Hope this helps!
