# Symbols --- The Arrow Trade Instrument API provides comprehensive access to all tradable instruments available on supported exchanges. This unified interface delivers market data in a structured CSV format, enabling seamless integration for algorithmic trading, portfolio management, and market analysis applications. ## Real-Time Instrument Data ### Complete Instrument Universe Access the complete catalog of tradable instruments across all supported exchanges and segments with a single API call. The instrument database is refreshed daily at **8:00 AM IST** to ensure accuracy and relevance for each trading session. **Example Request** ```bash curl --location 'https://edge.arrow.trade/all' \ --header 'appID: ' \ --header 'token: ' ``` > **Important:** Download instrument data only after 8:00 AM IST to ensure you receive the most current trading session tokens. Accessing the data before this time may result in stale instrument tokens from the previous trading session. ## Response Format The API returns comprehensive instrument data in CSV format with the following structure: ```csv Exchange,Segment,ExchSeg,Token,FullName,Symbol,TradingSymbol,Series,ISIN,LotSize,TickSize,PricePrecision,OptionType,Underlying,UnderlyingToken,StrikePrice,Expiry,FreezeQty,Lower Band,Upper Band,SurCodes,Events,ExchangeID NSE,CM,NSECM,3045,STATE BANK OF INDIA,SBIN,SBIN-EQ,EQ,INE062A01020,1,0.10,2,,,0,0.00,,0,1073.20,1311.60,,,3045 NSE,CM,NSECM,2885,RELIANCE INDUSTRIES LTD,RELIANCE,RELIANCE-EQ,EQ,INE002A01018,1,0.10,2,,,0,0.00,,0,1304.10,1593.70,,,2885 NSE,FO,NSEFO,104034,DIVISLAB,DIVISLAB,DIVISLAB30MAR26C6450,XX,,100,0.05,2,CE,DIVISLAB,10940,6450.00,30-Mar-2026,4000,61.75,301.55,,,104034 NSE,FO,NSEFO,104190,DIVISLAB,DIVISLAB,DIVISLAB28APR26P5800,XX,,100,0.05,2,PE,DIVISLAB,10940,5800.00,28-Apr-2026,4000,70.95,230.45,,,104190 NSE,FO,NSEFO,163082,TITAN,TITAN,TITAN30MAR26C3720,XX,,175,0.05,2,CE,TITAN,3506,3720.00,30-Mar-2026,7000,434.15,751.75,,,163082 NSE,FO,NSEFO,59577,BANKNIFTY,BANKNIFTY,BANKNIFTY24FEB26C43800,XX,,30,0.05,2,CE,BANKNIFTY,26009,43800.00,24-Feb-2026,600,15527.25,18524.05,,,59577 NSE,INDEX,NSEIDX,26016,,HangSeng BeES-NAV,,,,,1,,,,,,,,,,,,26016 NSE,INDEX,NSEIDX,26017,,India VIX,,,,,1,,,,,,,,,,,,26017 NSE,INDEX,NSEIDX,26000,,Nifty 50,,,,,1,,,,,,,,,,,,26000 NSE,INDEX,NSEIDX,26008,,Nifty IT,,,,,1,,,,,,,,,,,,26008 NSE,INDEX,NSEIDX,26013,,Nifty Next 50,,,,,1,,,,,,,,,,,,26013 NSE,INDEX,NSEIDX,26009,,Nifty Bank,,,,,1,,,,,,,,,,,,26009 ``` ## Different file Endpoints The following endpoints allows you to download file Segment wise | Segment | Endpoint | |-------|-----------| | ALL | `/all` | | NSE | `/nse` | | BSE | `/bse` | | MCX | `/mcx` | !!! note "MCX instruments" `GET /mcx` returns Multi Commodity Exchange instruments. Trading, quote, and margin APIs use exchange code **`MCXFO`** for commodity F&O contracts (for example `GOLDPETAL31JUL26F`). The CSV `ExchSeg` field for these contracts is typically `MCXFO`. ## Field Specifications ### Core Trading Fields ⭐ The following fields are essential for most trading operations and API interactions: | Field | Data Type | Description | |-------|-----------|-------------| | **ExchSeg** ⭐ | `string` | Exchange segment identifier: `NFO` (NSE F&O), `NSE` (NSE Equity), `BFO` (BSE F&O), `BSE` (BSE Equity), `MCXFO` (MCX F&O) | | **Token** ⭐ | `int64` | Unique instrument identifier required for all API operations | | **TradingSymbol** ⭐ | `string` | Primary trading symbol used in order placement and market data APIs | | **StrikePrice** ⭐ | `int64` | Option strike price (multiplied by 100 for precision) | ### Comprehensive Instrument Data | Field | Data Type | Description | |-------|-----------|-------------| | **LotSize** | `int64` | Minimum tradable quantity per lot | | **Symbol** | `string` | Exchange-recognized symbol identifier | | **CompanyName** | `string` | Complete registered company name | | **Exchange** | `string` | Primary exchange: `NSE` or `BSE` | | **Segment** | `string` | Market segment: `EQT` (Equity), `DER` (Derivatives) | | **Instrument** | `string` | Instrument classification: `EQ`, `FUTIDX`, `OPTIDX`, `FUTSTK`, `OPTSTK`, `BE`, `BL`, `SM` | | **ExpiryDate** | `string` | Contract expiration date (derivatives only) | | **Isin** | `string` | International Securities Identification Number | | **TickSize** | `decimal` | Minimum price movement in paisa | | **PricePrecision** | `int` | Decimal places supported in price quotations | | **Multiplier** | `decimal` | Contract multiplier for position sizing | | **PriceMultiplier** | `decimal` | Price calculation multiplier | | **OptionType** | `string` | Option classification: `CE` (Call European), `PE` (Put European) | | **UnderlyingExchange** | `string` | Exchange of the underlying asset (derivatives) | | **UnderlyingToken** | `int64` | Token identifier of the underlying instrument | | **ExchExpiryDate** | `int64` | Exchange expiry timestamp (add 10 years to epoch time) | | **UpdateTime** | `int64` | Last modification timestamp (epoch time) | | **MessageFlag** | `string` | Internal processing flag | ## Implementation Guidelines **Header:** All requests require valid `appID` and `token` headers for secure access to market data. **Data Freshness:** The instrument database is synchronized daily at 8:00 AM IST.
