I have demat & trading a/c. I am the beginer to share market. My question is : I purchase shares of a particular company i.e. wipro at the rate of Rs. 250 at 11 am. Is it possible to sell wipro shares on the same day at around 12.30 pm when the rate increases to 260. So that I can make a profit of Rs. 10. Can share market related people answer my query. What is the procedure to do so. For this whether online is required. Whether I have to keep some marginal amount as deposit in my trading a/c. Please clarify?
