Option Chain

Provides entire Option Chain of any Option Instrument. This includes OI, greeks, volume, top bid/ask and price data of all strikes of a particular underlying scrip.

Usage

from nubra_python_sdk.marketdata.market_data import MarketData
from nubra_python_sdk.start_sdk import InitNubraSdk, NubraEnv

# Initialize the Nubra SDK client
# Use NubraEnv.UAT for testing or NubraEnv.PROD for production
nubra = InitNubraSdk(NubraEnv.UAT)  # or NubraEnv.PROD

##using totp login and .env file 
#nubra = InitNubraSdk(NubraEnv.UAT, totp_login= True ,env_creds = True)

# Initialize MarketData with the client
mdInstance = MarketData(nubra)

# Get option chain for an instrument
result = mdInstance.option_chain("NIFTY",exchange="NSE")

Accessing Data

# Access the chain data
chain = result.chain
print(f"Current Price: {chain.current_price}")
print(f"ATM Strike: {chain.at_the_money_strike}")
print(f"Available Expiries: {chain.all_expiries}")


# Find and print ATM options
print("\nATM Options:")
atm_ce = next((opt for opt in chain.ce if opt.strike_price == chain.at_the_money_strike), None)
atm_pe = next((opt for opt in chain.pe if opt.strike_price == chain.at_the_money_strike), None)

if atm_ce:
    print("Call Option:")
    print(f"Ref Id: {atm_ce.ref_id}")
    print(f"Strike Price: {atm_ce.strike_price}")
    print(f"LTP: {atm_ce.last_traded_price}")
    print(f"LTP Change : {atm_ce.last_traded_price_change}")
    print(f"OI: {atm_ce.open_interest}")
    print(f"Volume: {atm_ce.volume}")
    print(f"Lot Size: {atm_ce.lot_size}")
    print(f"IV: {atm_ce.iv}")
    print(f"Delta: {atm_ce.delta}")
    print(f"Gamma: {atm_ce.gamma}")
    print(f"Theta: {atm_ce.theta}")
    print(f"Vega: {atm_ce.vega}")


if atm_pe:
    print("\nPut Option:")
    print(f"Ref Id: {atm_pe.ref_id}")
    print(f"Strike Price: {atm_pe.strike_price}")
    print(f"LTP: {atm_pe.last_traded_price}")
    print(f"LTP Change : {atm_pe.last_traded_price_change}")
    print(f"OI: {atm_pe.open_interest}")
    print(f"Volume: {atm_pe.volume}")
    print(f"Lot Size: {atm_pe.lot_size}")
    print(f"IV: {atm_pe.iv}")
    print(f"Delta: {atm_pe.delta}")
    print(f"Gamma: {atm_pe.gamma}")
    print(f"Theta: {atm_pe.theta}")
    print(f"Vega: {atm_pe.vega}")
