In this chapter we shall take a brief look at the trading system of futures and options on exchanges, including various types of orders. However, the best way to develop an understanding of the trading system is to actually watch the screen and observe trading. As stated earlier, futures and options are standardized contracts and like shares, they are traded on exchanges. Markets around the world can be classified into two main types based on the methods of booking a trade namely an “open outcry” market and the “electronic” market. Open outcry is the way of communication between professionals on an exchange, which involves shouting, or using hand signals to transfer information about buy and sell orders. In an open outcry markets, usually the trading takes place in a large hall known as “pit” where members are present and contracts are traded through continuous bids and offers. Thus, such a market brings together the buyers and sellers (through their brokers) on a platform for trading. In case of electronic trading, there are screen based broker dealing terminals, instead of the trading pit. Futures and options trading in India is electronic in nature, with the bids and offers, and the acceptance being displayed on the terminal continuously.

All the exchanges in India (BSE, NSE and MSEI) provide a fully automated screen-based trading platform for index futures, index options, stock futures and stock options. These trading systems support an order driven market and simultaneously provide complete transparency of trading operations. Derivative trading is similar to that of trading of equities in the cash market segment.

All these exchanges have developed software for the F&O market to facilitate efficient and transparent trading in futures and options instruments.

Entities in the trading system

Broadly there are four entities in the trading system

 Trading Members

 Trading cum Clearing Members (TM-CM)

 Professional Clearing Members (PCM)

 Self Clearing Member (SCM)

 Different types of orders in the trading system and order matching rule

 Selection criteria of stocks and index for futures and option trading

96 Trading Members:

They are members of Stock Exchanges. They can trade either on behalf of their clients or on their own account. The exchange assigns a trading member ID to each of its trading member. A trading member can have more than one user.

The number of users allowed for each trading member is decided by the exchange from time to time. A user must be registered with the exchange where he is assigned a unique user ID.

The unique trading member ID is common for all the users of a particular trading member. Therefore, it functions as a reference for all users of a particular trading member. Trading member is responsible to maintain adequate control over persons having access to the firm’s User IDs.

Trading cum Clearing Members:

A Clearing Member (CM) who is also a Trading Member (TM) of the exchange. Such CMs may clear and settle their own proprietary trades, their clients' trades as well as trades of other TM's & Custodial Participants

Professional Clearing Member:

Professional clearing member clears the trades of his associate Trading Member and institutional clients. PCM is not a Trading Member of the exchange. Typically banks or custodians become a PCM and clear and settle for TM's as well as for Custodial Participants

Self Clearing Member (SCM)

A Self Clearing Member is also a Trading Member on the exchange. Such CMs may clear and settle only their own proprietary trades and their clients' trades but cannot clear and settle trades of other TM's.

Participants:

Participant is a client of a trading member. Clients may trade through various trading members but settle through a single clearing member.

Market Timing of Derivative segment

Trading on the derivatives segment takes place on all working days of the week between 9:15 am and 3:30 pm.

Corporate Hierarchy

In the Futures and options trading software, trading member will have a provision of defining the hierarchy amongst users of the system. This hierarchy comprises:

 Corporate Manager

 Branch Manager and

 Dealer

Corporate Manager:

As a user, it is the highest level in a trading firm. Corporate Manager can perform all the functions such as order and trade related activities, receiving reports for all branches of the trading member firm and also all dealers of the firm. Along with this he can also

97

define exposure limits for the branches of the firm. This facility is available only to the corporate manager.

Branch Manager:

As a user, it is placed under the corporate manager. Branch Manager can perform and view order and trade related activities for all dealers under that branch.

Dealer:

Dealer is at the lowest level of the user hierarchy. He can only view his own orders and trades and does not have access to information on other dealers under either the same branch or in other branches.

Client Broker Relationship

A trading member would be responsible for various compliance related activities including Know Your Client (KYC) form, execution of Client Broker agreement, timely execution of orders given by clients, collection of adequate margins, maintain separate client bank account for segregation of client money, ensure timely pay-in and pay-out of funds, timely issue of contract notes, resolve clients’ complaints, sending periodical statement of accounts, maintain unique client code, etc.

Order types and conditions

In the trading system, trading members are allowed to enter orders with various conditions attached to them as per their requirements. These conditions are broadly divided into the following categories:

 Time conditions

 Price conditions

 Various combinations of the above are allowed providing flexibility to the users. Time conditions

Day order: A Day order is an order which is valid for a single day on which it is entered. If

the order is not executed during the day, the trading system cancels the order automatically at the end of the day.

Immediate or cancel (IOC): User is allowed to buy/sell a contract as soon as the order is

released into the trading system. An unmatched order will be immediately cancelled. Partial order match is possible in this order, and the unmatched portion of the order is cancelled immediately.

Price condition

Limit order: It is an order to buy or sell a contract at a specified price. The user has to

specify this limit price while placing the order and the order gets executed only at this specified limit price or at a better price than that (lower in case of buy order and higher in case of a sell order).

Market order: A market order is an order to buy or sell a contract at the best bid/offer

price currently available in the market. Price is not specified at the time of placing this order. The price will be the currently available price in the market i.e., a buy market

98

order will get executed at the best price at which the seller is ready to sell and a sell market order will get executed at the best price at which the buyer is ready to buy.

Stop-loss order: A stop loss is an order to buy (or sell) a security once the price of the

security climbed above (or dropped below) a trigger price. The stop-loss order gets activated when the trigger price is reached/crossed and enters the market as a market order or as a limit order, as defined at the time of placing this stop-loss order. To illustrate, suppose a trader buys ABC Ltd. shares at Rs 100 in expectation that the price will rise. However, prices starts declining below his buy price, trader would like to limit his losses. Trader may place a limit sell order specifying a trigger price of Rs 95 and a limit price of Rs 92. The trigger price has to be between last traded price and limit price while placing the sell limit order. Once the market price of ABC breaches the trigger price i.e. Rs 95, the order gets converted to a limit sell order at Rs 92. (Trigger Price is the price at which the order gets triggered from the stop loss book.)

Order Matching Rules

In India, F&O platforms offer an order driven market, wherein orders match automatically on price time priority basis.

Orders, as and when they are received, are first time stamped and then immediately processed for potential match. If a match is not found, then the orders are stored in different 'books'. Orders are stored in price-time priority in various books in the following sequence:

 Best Price

 Within Price, by time priority.

The best buy order will match with the best sell order. An order may match partially with another order resulting in multiple trades. For order matching, the best buy order is the one with highest price and the best sell order is the one with lowest price. This is because the computer views all buy orders available from the point of view of a seller and all sell orders from the point of view of the buyers in the market.

Price Band

There are no price bands applicable in the derivatives segment. However, in order to prevent erroneous order entry, operating ranges and day minimum/maximum ranges are kept as below:

 For Index Futures: at 10% of the base price

 For Futures on Individual Securities: at 10% of the base price

 For Index and Stock Options: A contract specific price range based on its delta value is computed and updated on a daily basis.

In view of this, orders placed at prices which are beyond the operating ranges would reach the Exchange as a price freeze.
