Futures hedging query???

Currency Futures are Exchange Traded Products.They are traded on exchange.unlike a OTC Product say Forward contract,they are very transparent. They are standardized by Exchange & are sold in contracts. one contract usually contains 1000 USD. Currency futures are available in 4 currency pairs.Check NSE website. There is never physical delivery of underlying,it always Cash settled,on daily basis or has to be Settled on the last date of the month. RBI reference rate,2 days prior to the settlement is considered for settlement. its a handy tool for hedging. U need to deposit a margin money,with the Stock broker or a bank to Strike a deal in NSE.. it could also be used for Speculation or Arbitrage..but could prove risky.
