📊 Metrics Glossary & Abbreviations

Understand what each metric and column name in NSE's publicly available End-Of-Day (EOD) dataset stands for. Daily Metrics capture single-day trading session activity, volume, and overnight position changes, while Gross Metrics represent total outstanding positions, cumulative contract turnover, and contract-lifetime aggregates.

📅 Daily Metrics (Day-Wise Activity & Changes)

Single-day session figures measuring immediate trading flow, daily liquidity, and overnight position additions or liquidation.

Metric Code Name, Definition & Calculation
OPEN_INT_CHG Daily Open Interest Change: Net contracts added or unwound during the single session (Today's Open Interest − Yesterday's Open Interest). Positive = new position build-up; Negative = liquidation/profit booking.
TRD_QTY Traded Quantity (Volume): Total number of underlying shares or index units bought and sold across all executed transactions during the session.
NO_OF_CONT Number of Contracts: Total derivative contract lots traded on the exchange floor during the session (TRD_QTY ÷ Market Lot Size).
NO_OF_TRADE Number of Trades: Total count of individual orders/trade executions matched on the exchange order book during the session. High trades/contract indicates retail participation, low trades with high volume indicates block/institutional trades.
PR_VAL Premium Value: Total monetary value in ₹ exchanged for option premiums during the single session (Traded Quantity × Option Premium Price). Applies to Options.
TRD_VAL Traded Value (Turnover): Total monetary amount in ₹ traded during the session (Traded Quantity × Option Premium for options; Traded Quantity × Futures Price for futures).
NOTION_VAL Notional Value (Exposure): Total face valuation of the underlying asset controlled (Traded Quantity × Strike/Spot Price). For options, Notional Value is significantly larger than Traded Premium Value.
*_CHG Daily Delta / Change Metrics: Single-day change in value vs previous trading day for any metric (e.g. TRD_QTY_CHG, PR_VAL_CHG).
CE / PE Call / Put Options: CE = Call European (right to buy); PE = Put European (right to sell).
UNDERLYING_VAL Underlying Spot Price: Closing cash market spot price or underlying index price for the benchmark asset on the selected trading day.
💡 Best for: Identifying fresh daily institutional buying/selling, short-term momentum shifts, single-day breakout confirmation, and daily position building or unwinding.

🧮 Valuation & Snapshot Metrics (Turnover & Open Commitments)

Core positioning and valuation figures measuring total active contracts, turnover, premium commitment, and derived contract ratios.

Metric Code Name, Definition & Calculation
OPEN_INT Open Interest Snapshot: Total active, open derivative contracts built up and held overnight up to the selected date. Measures total outstanding market commitment.
PR_VAL Premium Value: Total monetary value in ₹ paid for option premiums traded during the session (Traded Qty × Weighted Premium).
TRD_VAL Traded Value: Total monetary turnover in ₹ traded in futures contracts during the session.
NOTION_VAL Notional Value: Total underlying contract valuation in ₹ (Traded Qty × Strike/Underlying Price).
LOT_SIZE Market Lot Size: Fixed number of underlying shares or index units per single derivative contract.
OPEN_INT_CHG Net OI Change: Daily net difference in open interest compared to the preceding trading session.
PCR (Put-Call Ratio) Put-Call Ratio: Ratio computed as Total Put Open Interest (or Volume) ÷ Total Call Open Interest (or Volume). Indicates macro market sentiment.
💡 Best for: Locating major support & resistance strike clusters (high Open Interest concentrations), analyzing total contract liquidity, and measuring capital commitment across contract expiries.
🎛️ Filters & Controls Guide

How to configure filters on Options & Futures pages to isolate specific market insights.

📅 Select Date & Fast Jump (2010–Present)

Use the date picker or click Prev / Next to step day-by-day. Use the Fast Jump dropdowns to select a specific Month (e.g. Jul) and Year (e.g. 2024) to jump directly into historical periods.

☑️ Monthly Expiry Only Toggle

When checked, weekly option/future contracts are filtered out, displaying only contract expiries that occur on the final Thursday/Wednesday of the month. Uncheck it to see all contracts including weekly expiries.

🎯 Strike Price & Expiry Date Selectors

Select specific contract expiry dates or filter by individual Strike Price to analyze Open Interest build-up or liquidation at critical support/resistance levels.

📊 Daily Session vs Multi-Day Cumulative Analysis

On Historical pages, switch between Single Day (shows daily incremental activity on the selected date) and Cumulative Window (sums changes over rolling 3-day, 5-day, or 10-day windows).

🧮 Advanced Custom Metrics Builder Tutorial

You can build, group, and plot multi-term mathematical formulas using 2, 3, or 4 metrics, bracketed order of operations, and saved metric composition directly across Options, Futures, Equity, and Historical dashboards.

How to Create & Nest Custom Formulas:

  1. Go to any dashboard (Options, Futures, Equity, or Historical Scanners).
  2. Expand the 🧮 Custom Metrics card.
  3. Select Metric A (choose from standard raw columns or previously saved custom metrics to nest sub-terms).
  4. Choose your operator: ÷ Divide, × Multiply, + Add, or − Subtract.
  5. Select Metric B (and optionally Metric C and Metric D).
  6. Set Grouping (Brackets) to define order of operations:
    • Step 1 First: Evaluate (A op1 B) op2 C op3 D
    • Step 2 First: Evaluate A op1 (B op2 C) op3 D
    • Group Pairs: Evaluate (A op1 B) op2 (C op3 D)
  7. Check the Formula Preview box to confirm exact mathematical execution order.
  8. Click ➕ Add Metric.
⭐ Top Predefined Formula: PR_VAL ÷ OPEN_INT_CHG measures the total traded premium capital relative to net daily Open Interest change, identifying where high-conviction institutional money is entering contracts.
💡 Pro Tip: Saved custom metrics are instantly available under 🧮 Saved Custom Metrics in the dropdowns. You can nest multiple saved formulas together to create sophisticated derivative indicators (e.g. (Saved_Ratio_1 + OPEN_INT) ÷ Saved_Ratio_2)!
