Spot Price: The price at which an asset trades in the cash market. This is the underlying value of Nifty on Jan 27, 2016 which is 7,437.75

Futures Price: The price of the futures contract in the futures market. The closing price of Nifty in futures trading is Rs. 7433.40. Thus Rs. 7433.40 is the future price of Nifty, on a closing basis.

Contract Cycle: It is a period over which a contract trades. On Jan 27, 2016, the maximum number of index futures contracts is of 3 months contract cycle- the near month (Jan 2016), the next month (Feb 2016) and the far month (March 2016). Every futures contract expires on last Thursday of respective month (in this case Jan 28, 2016). And, a new contract (in this example - April 2016) is introduced on the trading day following the expiry day of the near month contract (in this example – on Jan 29, 2016).

Expiration Day: The day on which a derivative contract ceases to exist. It is last trading day of the contract. The expiry date in the quotes given is Jan 28, 2016. It is the last Thursday of the expiry month. If the last Thursday is a trading holiday, the contracts expire on the previous trading day. On expiry date, all the contracts are compulsorily settled. If a contract is to be continued then it must be rolled to the near future contract. For a long position, this means selling the expiring contract and buying the next contract. Both the sides of a roll over should be executed at the same time. Currently, all equity derivatives contracts (both on indices and individual stocks) on NSE are cash settled whereas on BSE, derivative contracts on indices are cash settled while the contracts on individual stocks are delivery settled.

Tick Size: It is minimum move allowed in the price quotations. Exchanges decide the tick sizes on traded contracts as part of contract specification. Tick size for Nifty futures is 5 paisa. Bid price is the price buyer is willing to pay and ask price is the price seller is willing to sell.

Contract Size and contract value: Futures contracts are traded in lots and to arrive at the contract value we have to multiply the price with contract multiplier or lot size or contract size. For Nifty 50, lot size is 75 . For individual stocks, it varies from one stock to another. The lot size changes from time to time. In the Nifty quotes given above, contract value would be equal to Nifty Futures Price * Lot Size = 7433.40 * 75 = Rs. 5,57,505. Recently NSE has introduced minimum contract size as Rs 5 Lakhs for any contracts

Basis: The difference between the spot price and the futures price is called basis. If the futures price is greater than spot price, basis for the asset is negative. Similarly, if the spot price is greater than futures price, basis for the asset is positive. On Jan 27, 2016, spot price > future price thus basis for nifty futures is positive i.e. (7,437.75-7433.40 = Rs. 4.35).

Importantly, basis for one-month contract would be different from the basis for two or three month contracts. Therefore, definition of basis is incomplete until we define the basis vis-a-vis a futures contract i.e. basis for one month contract, two months contract etc. It is also important to understand that the basis difference between say one month and two months futures contract should essentially be equal to the cost of carrying the underlying asset between first and second month. Indeed, this is the fundamental of linking various futures and underlying cash market prices together.

During the life of the contract, the basis may become negative or positive, as there is a movement in the futures price and spot price. Further, whatever the basis is, positive or negative, it turns to zero at maturity of the futures contract i.e. there should not be any difference between futures price and spot price at the time of maturity/ expiry of contract. This happens because final settlement of futures contracts on last trading day takes place at the closing price of the underlying asset.

Cost of Carry Cost of Carry is the relationship between futures prices and spot prices. It measures the storage cost (in commodity markets) plus the interest that is paid to finance or ‘carry’ the asset till delivery less the income earned on the asset during the holding period. For equity derivatives, carrying cost is the interest paid to finance the purchase less (minus) dividend earned.

For example, assume the share of ABC Ltd is trading at Rs. 100 in the cash market. A person wishes to buy the share, but does not have money. In that case he would have to borrow Rs. 100 at the rate of, say, 6% per annum. Suppose that he holds this share for one year and in that year he expects the company to give 200% dividend on its face value of Rs. 1 i.e. dividend of Rs. 2. Thus his net cost of carry = Interest paid – dividend received = 6 – 2 = Rs. 4. Therefore, break even futures price for him should be Rs.104.
It is important to note that cost of carry will be different for different participants.

Margin Account As exchange guarantees the settlement of all the trades, to protect itself against default by either counterparty, it charges various margins from brokers. Brokers in turn charge margins from their customers. Brief about margins is as follows:

 Initial Margin The amount one needs to deposit in the margin account at the time entering a futures contract is known as the initial margin.
Let us take an example - On Jan 27, 2016 a person decided to enter into a futures contract. He expects the market to go up so he takes a long Nifty Futures position for 25th Feb 2016 expiry. On Jan 27, 2016 Nifty closes at 7433.40.

The contract value = Nifty futures price * lot size = 7433.40 * 75 = Rs. 557,505.

Therefore, Rs 557,505 is the contract value of one Nifty Future contract expiring on Feb 2016.

Assuming according to the SPAN® calculation margin comes at around 5% of the contract value as initial margin, the person has to pay him Rs. 27,875.25 as initial margin. Both buyers and sellers pay initial margin, as there is an obligation on both the parties to honour the contract.

The initial margin is dependent on price movement of the underlying asset. As high volatility assets carry more risk, exchange would charge higher initial margin on them.

Exposure Margin: Time to Time basis exchange releases a circular for exposure margin levied on Futures Index & Futures Stock. For Index(s) exposure margin as on date 27 Jan 2016 is 3% which means, both buyers and sellers pay exposure margin over and above Initial margin. In our case it would be 557,505 *3% = 16,725.15

Mark to Market (MTM) In futures market, while contracts have maturity of several months, profits and losses are settled on day-to-day basis – called mark to market (MTM) settlement. The exchange collects these margins (MTM margins) from the loss making participants and pays to the gainers on day-to-day basis.

Let us understand MTM with the help of the example. Suppose a person bought a futures contract at the lowest price on Jan 27, 2016 at 7415. He paid an initial margin of Rs. 27,875.25 & Exposure Margin of Rs 16725.15 as calculated above. On the same day Nifty futures contract closes at 7433.40. This means that he benefits due to the 18.4 points gain on Nifty futures contract. Thus, his net gain is of Rs.  1,380 (18.4 * 75). This money will be credited to his account and next day the position will start from 7433.40.

Open Interest and Volumes Traded An open interest is the total number of contracts outstanding (yet to be settled) for an underlying asset. The quotes given above show us on Jan 27, 2016 Nifty futures have an open Interest of 12,215,625. It is important to understand that number of long futures as well as number of short futures is 12,215,625. This is because total number of long futures will always be equal to total number of short futures. Only one side of contracts is considered while calculating/ mentioning open interest. On Jan 25, 2016, the open interest in Nifty futures was 15,204,900. This means that there is a decrease of 2,989,275 in the open interest on Jan 27, 2016. The level of open interest indicates depth in the market.
Volumes traded give us an idea about the market activity with regards to specific contract over a given period – volume over a day, over a week or month or over entire life of the contract.
