Understanding the Strangle Option Strategy
Author: Analyst, algotradingdesk.com
Introduction
In the dynamic world of options trading, the Strangle Option Strategy is a powerful volatility-based approach, especially when traders expect significant movement in the underlying asset but are uncertain about the direction. This strategy is widely adopted by professional options traders, particularly in the Indian derivatives market where NIFTY options offer excellent liquidity and tight bid-ask spreads.
At algotradingdesk.com, we believe in integrating structured strategies with data-driven execution. This blog will guide you through the construction, logic, benefits, risks, and application of the Strangle Strategy, including a practical example using NIFTY 24000 strike prices and the updated lot size of 75.
What is a Strangle Strategy?
A Strangle is a neutral options strategy involving the simultaneous buying or selling of an Out-of-the-Money (OTM) Call and Put option with the same expiration date but different strike prices.
Types of Strangle Strategies:
- Long Strangle – Buy OTM Call + Buy OTM Put
- Short Strangle – Sell OTM Call + Sell OTM Put
- The Long Strangle profits from high volatility.
- The Short Strangle profits from low volatility and time decay.
When to Use a Long Strangle?
The Long Strangle is ideal when:
- You expect a large market move but are unsure about the direction (e.g., before RBI decisions, earnings announcements, or geopolitical events).
- Implied Volatility (IV) is low and expected to rise.
- The market is consolidating and a breakout is anticipated.
Example: Long Strangle on NIFTY (24000 Spot Level)
- Buy 1 Lot NIFTY 24200 CE @ ₹100
- Buy 1 Lot NIFTY 23800 PE @ ₹120
- Total Premium Paid = ₹100 + ₹120 = ₹230
- Lot Size = 75
- Total Capital at Risk = ₹230 x 75 = ₹17,250
Payoff Calculation
- Maximum Loss: Limited to total premium paid (₹17,250), if NIFTY expires between the two strike prices.
- Maximum Profit: Theoretically unlimited on the upside and substantial on the downside. Profits increase as the price moves significantly beyond the breakeven points.
Breakeven Points:
- Upper Breakeven = 24200 + ₹230 = 24430
- Lower Breakeven = 23800 – ₹230 = 23570
Advantages of the Long Strangle Strategy
- Neutral Directional Bias – No need to predict direction, only volatility.
- Unlimited Profit Potential – Ideal during expected news or breakout scenarios.
- Defined Risk – Maximum loss is limited to the premium paid.
- Simple Construction – Involves just two legs; easy to monitor.
Drawbacks of the Long Strangle
- Time Decay (Theta Loss) – Both options lose value over time if the market remains stagnant.
- Requires Strong Movement – If NIFTY doesn’t move enough, the strategy results in a net loss.
- Higher Cost than Single-Leg Options – Due to buying both Call and Put options.
Short Strangle Setup: Neutral to Low Volatility Strategy
- Sell 1 Lot 24200 CE @ ₹100
- Sell 1 Lot 23800 PE @ ₹120
- Total Premium Collected = ₹230
- Lot Size = 75
- Maximum Profit = ₹230 x 75 = ₹17,250, if NIFTY closes between 23800 and 24200
- Risk: Unlimited on sharp movements beyond the breakeven points
Advantages of the Short Strangle
- Neutral Bias with Profit from Time Decay
- Income from Premiums – Immediate inflow of capital.
- Simple Execution – Only two option legs to manage.
Drawbacks of the Short Strangle
- Unlimited Risk – Sharp movements can cause large losses.
- High Margin Requirement – Capital-intensive compared to long positions.
- Requires Low Volatility – Strategy fails if volatility spikes.

- Blue Line: Long Strangle – Profits from volatility in either direction
- Red Dashed Line: Short Strangle – Profits in a range-bound scenario; risks increase beyond breakevens
