description	Options trading with OpenAlgo - single leg orders, multi-leg strategies (Iron Condor, Straddle, Strangle, Spreads), options chain analysis, and Greeks calculation

OpenAlgo Options Trading

Execute options trading strategies using OpenAlgo's unified Python SDK. Supports index options (NIFTY, BANKNIFTY, FINNIFTY), stock options, and complex multi-leg strategies.

Environment Setup

from openalgo import api

client = api(
    api_key='your_api_key_here',
    host='http://127.0.0.1:5000'
)

Quick Start Scripts

Single Leg Options Order

python scripts/options_order.py --underlying NIFTY --expiry 30JAN25 --offset ATM --option-type CE --action BUY --quantity 75

Iron Condor Strategy

python scripts/iron_condor.py --underlying NIFTY --expiry 30JAN25 --quantity 75

Straddle Strategy

python scripts/straddle.py --underlying BANKNIFTY --expiry 30JAN25 --action BUY --quantity 30

Options Symbol Format

OpenAlgo uses standardized symbol formats:

Type	Format	Example
Index Options	`[INDEX][DDMMMYY][STRIKE][CE/PE]`	`NIFTY30JAN2526000CE`
Stock Options	`[SYMBOL][DDMMMYY][STRIKE][CE/PE]`	`RELIANCE30JAN251400CE`
Index Futures	`[INDEX][DDMMMYY]FUT`	`NIFTY30JAN25FUT`

Offset System

OpenAlgo uses an intuitive offset system to select strikes relative to ATM:

Offset	Meaning	Example (NIFTY ATM=26000)
`ATM`	At The Money	26000
`ITM1`	1 strike In The Money	CE: 25950, PE: 26050
`ITM2`	2 strikes In The Money	CE: 25900, PE: 26100
`OTM1`	1 strike Out of The Money	CE: 26050, PE: 25950
`OTM2`	2 strikes Out of The Money	CE: 26100, PE: 25900
`OTM5`	5 strikes Out of The Money	CE: 26250, PE: 25750

    expiry_date="30JAN25",  # Weekly expiry
    legs=[

        {"offset": "OTM5", "option_type": "PE", "action": "SELL", "quantity": 75}
    ]
)

        {"offset": "OTM3", "option_type": "CE", "action": "SELL", "quantity": 30}
    ]
)

Event Day Volatility Play

# Long Straddle before results/events
response = client.optionsmultiorder(
    strategy="Event Straddle",
    underlying="RELIANCE",
    exchange="NSE",
    expiry_date="30JAN25",
    legs=[
        {"offset": "ATM", "option_type": "CE", "action": "BUY", "quantity": 250},
        {"offset": "ATM", "option_type": "PE", "action": "BUY", "quantity": 250}
    ]
)

Butterfly Spread (Low Capital)

response = client.optionsmultiorder(
    strategy="Long Butterfly",
    underlying="NIFTY",
    exchange="NSE_INDEX",
    expiry_date="30JAN25",
    legs=[
        {"offset": "ITM2", "option_type": "CE", "action": "BUY", "quantity": 75},
        {"offset": "ATM", "option_type": "CE", "action": "SELL", "quantity": 150},
        {"offset": "OTM2", "option_type": "CE", "action": "BUY", "quantity": 75}
    ]
)

Margin Calculation

Calculate required margin before placing orders:

margin = client.margin(positions=[
    {
        "symbol": "NIFTY30JAN2526000CE",
        "exchange": "NFO",
        "action": "SELL",
        "product": "NRML",
        "pricetype": "MARKET",
        "quantity": "75"
    },
    {
        "symbol": "NIFTY30JAN2525000CE",
        "exchange": "NFO",
        "action": "BUY",
        "product": "NRML",
        "pricetype": "MARKET",
        "quantity": "75"
    }
])

print(f"Total Margin Required: {margin['data']['total_margin_required']}")
print(f"SPAN Margin: {margin['data']['span_margin']}")
print(f"Exposure Margin: {margin['data']['exposure_margin']}")

Notes

Always check available margin before placing option sell orders
Use splitsize parameter for large orders to avoid freeze quantity limits
Weekly options expire on Thursday, monthly on last Thursday
NIFTY lot size is 75, BANKNIFTY is 30
Use Analyzer mode for paper trading: client.analyzertoggle(mode=True)
