hii..i am scratching my head after seeing d calls given in equity for 4 to 5 days in the stock channels. The buy calls r ok but they also give sell calls means to sell some equity in a given day buy it after some days with a specific target.But as far as a know that a sell order has to b cover up within the same day otherwise one have to face a auction penalty. They also doesnt mention that the calls r in future n option. Is this possible in equity??? Can anybody please make it clear.....?????????
