List of Entities in Trading System

The ETCD market is a tightly regulated network where each participant performs a distinct, legally defined function. At the top sits the recognised stock exchange (NSE or BSE) that provides the electronic platform for order matching. Below the exchange, the clearing corporation guarantees trade settlement, while brokers and trading members act as the bridge between investors and the market.

Depository participants (DPs) maintain the electronic records of currency derivative contracts, ensuring that ownership changes are reflected accurately in the dematerialised environment. Market makers and liquidity providers add depth to the order book, offering continuous bid‑ask quotes that enable smooth execution even in volatile conditions.

For the NISM exam, you must be able to map each of these entities to its core responsibility – whether it is order routing, trade guarantee, settlement, or custody. Questions often present a flow diagram; recognising each block helps you answer both multiple‑choice and assertion‑reason type items quickly.

The exchange operates the order‑matching engine that receives buy and sell orders from registered brokers. It enforces market‑wide parameters such as contract specifications, tick size, and daily price limits, all of which are prescribed by SEBI’s Currency Derivatives Regulations.

When an order is placed, the exchange validates the order against the participant’s margin and risk limits before it enters the limit order book. Matching is done on a price‑time priority basis, ensuring fairness and transparency. The exchange also publishes real‑time market data, which is essential for price discovery and for market makers to quote competitive spreads.

Exam tip: A common mistake is to attribute trade guarantee to the exchange. Remember, the exchange merely matches orders; the clearing corporation provides the guarantee of settlement.

Each exchange has an associated clearing corporation – for NSE it is NSE Clearing Ltd. The clearing corporation becomes the counter‑party to every trade, thereby eliminating direct credit risk between the buyer and seller.

It calculates the daily mark‑to‑market (MTM) profit or loss for each participant, collects variation margin, and ensures that the net settlement amount is transferred through the settlement bank on the settlement day (T+2 for currency futures). The clearing corporation also maintains the default fund, which is used to cover losses if a participant defaults.

In NISM questions, look for statements that mention "guarantee of settlement" or "variation margin collection" – these point directly to the clearing corporation.

Registered brokers (also called trading members) are the only entities authorised to place orders on behalf of clients in the ETCD market. They must be members of the exchange and hold a valid SEBI‑approved brokerage licence.

Before forwarding an order to the exchange, brokers verify the client’s KYC, assess available margin, and apply any risk limits imposed by the exchange or the clearing corporation. They also provide order‑type options (limit, market, stop‑loss) and may offer advisory services, though advisory activities are regulated separately under the Investment Advisers Regulations.

Exam relevance: Questions may ask which entity can directly access the order‑matching engine – the answer is always the broker/trading member, not the DP or the clearing corporation.

Depository participants are registered with the Central Depository Services (India) Ltd. (CDSL) or National Securities Depository Ltd. (NSDL). In the context of currency derivatives, DPs maintain the electronic ledger that records the ownership of each derivative contract.

When a trade is settled, the clearing corporation instructs the DP to debit the seller’s account and credit the buyer’s account with the appropriate number of contracts. This dematerialised process eliminates the need for physical certificates and reduces settlement risk.

Students often confuse DPs with brokers. Remember: brokers originate orders; DPs only record the post‑settlement ownership change.

Market makers are specialised brokers who commit to providing both buy (bid) and sell (ask) quotes for a set of currency derivative contracts throughout the trading session. Their primary aim is to narrow the bid‑ask spread and enhance market depth.

Liquidity providers may also be designated by the exchange under a "Designated Market Maker" (DMM) framework. They are required to maintain a minimum quoted size and must adhere to strict compliance norms, including periodic reporting of their inventory to the exchange.

Exam tip: If a question mentions "continuous two‑way quotes" or "obligation to maintain minimum depth," the correct answer will involve market makers or designated liquidity providers.
