Tracking Futures and Options data

Accurate futures and options data enables traders to price contracts, monitor position risk, and meet SEBI’s daily reporting obligations. Without reliable data, a trader cannot determine whether a contract is in‑the‑money, calculate potential profit or loss, or adjust margins correctly.

The NISM exam frequently tests the ability to differentiate between live (real‑time) and delayed data, as well as the consequences of using the wrong data feed for margin calculations. Understanding the data flow also helps you answer scenario‑based questions where a broker’s platform may show a 15‑minute delayed quote.

In practice, data drives the decision to enter, modify, or exit a trade. For example, a sudden spike in open interest may signal a large institutional entry, prompting a risk‑manager to tighten limits.

• Live data → required for intraday position monitoring.
• Delayed data → acceptable for end‑of‑day reporting but not for execution decisions.

The key data points for an equity future are the contract code, expiry date, underlying spot price, last traded price (LTP), bid‑ask spread, daily high/low, settlement price, and open interest. Each of these is published on the exchange’s website and through market data vendors.

Margin requirements are calculated on the basis of the settlement price and the contract’s multiplier. Therefore, the settlement price is the most exam‑relevant figure when a question asks for the required margin for a given future.

For risk‑management, traders watch the change in open interest together with price movement. A simultaneous rise in price and open interest typically signals bullish sentiment, a pattern often highlighted in NISM practice questions.

Option contracts add several unique fields: strike price, option type (call/put), implied volatility, Greeks (Delta, Gamma, Theta, Vega), and the option chain displaying LTP, bid‑ask, open interest, and volume for each strike.

Intrinsic value is the immediate exercisable amount (max[Spot‑Strike, 0] for calls). Time value is the premium remaining after subtracting intrinsic value. The exam often asks you to compute intrinsic and time value given spot, strike and premium.

Open interest for options, like futures, indicates the number of outstanding contracts but does not convey the direction (long or short). The direction is inferred from the combination of price movement and changes in open interest.

In India, the primary sources of futures and options data are the exchange portals (NSE, BSE), authorized data vendors (e.g., Bloomberg, Reuters), and broker‑provided trading terminals (e.g., Zerodha Kite, Angel Broking). Each source differs in latency, cost, and depth of information.

Exchange websites provide free delayed data (usually 15‑minute lag) and a limited real‑time feed for registered members. Data vendors deliver sub‑second real‑time streams for a subscription fee, which is essential for high‑frequency traders.

Broker platforms often integrate the exchange’s real‑time feed and add order‑book depth, making them the most convenient source for retail traders. However, the exam may test your awareness that broker data is still subject to the exchange’s reporting standards.

An option chain lists all available strikes for a given expiry, showing LTP, bid‑ask, open interest and volume side‑by‑side for calls and puts. The chain is the fastest way to assess market sentiment across different strike levels.

To determine moneyness, compare the underlying spot price with the strike. If Spot > Strike for a call, the option is In‑the‑Money (ITM). For a put, Spot < Strike indicates ITM. The exam often presents a spot price and asks which strikes are ITM, OTM or ATM.

Changes in open interest across strikes can hint at where market participants expect the price to move. A surge in open interest at a particular strike may act as a resistance or support level, a nuance that appears in scenario‑based questions.

Traders use live futures and options data to calculate exposure, Value‑at‑Risk (VaR), and margin requirements. The key inputs are the current LTP, the contract multiplier, and the open interest for each position.

For a short futures position, an increase in price directly raises the potential loss. By monitoring the option chain, a trader can hedge using options whose delta offsets the futures exposure. The exam may ask you to identify the appropriate hedge ratio based on delta values.

SEBI mandates daily reporting of net positions and the highest and lowest price of the day (H/L). Failure to report accurate data can attract penalties, a point that often appears in compliance‑related questions.

Many candidates mix up delayed data with live data, leading to wrong margin calculations. Always verify whether the quoted price is real‑time (≤ 1 second) or delayed (≥ 15 minutes) before using it in any computation.

Another frequent error is forgetting to include the contract multiplier when converting price to monetary exposure. The exam explicitly tests this by providing price figures and asking for total contract value.

Finally, students sometimes overlook SEBI’s requirement to report the highest and lowest price of the day for each contract. Remember that H/L is part of the daily position report, not just an optional statistic.
