I have a account at sharekhan. I had purchased some trades and then i selled the shares . When i purchased the shares my account balance as per normal terms showed the amount deducted after buying those shares and when i selled those shares the amount got added to my share khan account and the amount increased . Does that mean i can buy shares upto that amount now ? and will the same thing continue till i dont reach the limit ? TPls tell me the brokerage ?
