Dear traderji , creditviolet , ivanboesky & senior members I have following doubts in cash & futures arbitrage can you help me to solve them 1) it is said that future price converge with spot price on expiry/settlement day. is it still happening in NSE today also because when you look at the newspapers on the expiry/settlement day the closing price of the future for the current month is different from the closing price of spot on the expiry / settlement day? Please enlighten me on this aspect. 2) if the future price converge with the spot price on the expiry day , then at what time of the day does it take place ? 3) how to sell in the spot market & buy in the future market simultaneously on the expiry / settlement day to take advantage of cash & future arbitrage that developed earlier to expiry ?
