Calculate risk involved in F&O

Your client now understands how to read the Option Chain to gauge sentiment, but they need to understand exactly what happens to their capital when the stock price moves.

A Payoff Structure illustrates the net profit or loss earned by a trader across different underlying stock prices on the day of contract expiration. To make this practical, we will evaluate trades on Reliance Industries Ltd. (RELIANCE) using a benchmark entry price of ₹1,310.30 (matching its actual trading level in July 2026).

As a Risk Analyst, your job is to answer this question by analysing the Payoff Structure of different Futures and Options strategies.

Instead of calculating everything manually, you will use the Opstra Strategy Builder to visually analyse how profits and losses change as Reliance's share price moves.

Topic : Futures & Options

1) Long and short positions

2) Payoff Chart

3) Contract life cycle

4) Mark-to-market mechanism

• The Strategy: The trader expects Reliance shares to rise aggressively.

• The Trade: Buy 1 RELIANCE Futures contract at an entry price of ₹1,310.30.

• Formula: Profit / Loss = Expiry Price - Entry Price

Understanding Long Futures Position

Observation: A Long Futures position offers unlimited profit potential if the stock price rises, but carries unlimited risk (loss) if the stock price falls

Look at the dynamic linear graph generated next to your metrics panel to understand your real-time risk boundaries:

The Shape: A straight diagonal line slicing from bottom-left to top-right.

Green Zone (Profit Area): Shaded green in the upper-right quadrant as prices rise towards ₹1,321, and beyond.

Red Zone (Loss Area): Shaded orange in the lower-left quadrant as prices plunge lower towards ₹1,280 and beyond.

Short Futures Position

6

• The Strategy: The trader expects Reliance shares to fall sharply.

​

• The Trade: Sell (short) 1 RELIANCE Futures contract.

​

• Formula: Profit / Loss = Entry Price - Expiry Price

Once you click "Sell" and add the position, Opstra builds your live short-selling analysis board. Scroll down right below the trade setup console to inspect:

Active Position: You will see S 1x 28JUL2026 FUTURES active at an entry price of ₹1,310.30. The red S denotes a Sell (Short) position.

• Max Profit & Max Loss: Notice that both fields are marked as ₹ Undefined. This visually proves to students that just like a long position, a short futures position carries theoretically unlimited risk if the stock price surges upwards against you.

​

• Estimated Margin/Premium: It shows ₹ +1,15,396, This is the approximate margin amount that the trader must maintain in their trading account before selling one RELIANCE Futures contract.

Look at the interactive linear chart to see how the profit and loss behavior completely flips compared to the long position:

• The Diagonal Line Pattern: Because this is a Short (Sell) Futures position, the chart features a straight diagonal line sloping downward from the top-left corner to the bottom-right corner.

• The Green Zone (Profit Area on the Left): Observe the upper-left quadrant shaded in green. As the underlying stock price falls below your entry level (moving left towards ₹1,280, ₹1,239, ₹1,198, and lower), the diagonal line climbs higher into positive profit territory.

​

• The Shaded Orange/Red Zone (Loss Area on the Right): Observe the lower-right quadrant shaded in orange. If the stock unexpectedly rallies past your entry point (moving right towards ₹1,321, ₹1,362, ₹1,403, and higher), the line plunges straight down into negative territory, visually confirming that short futures carry theoretically unlimited upside risk.

Long Call Option (Buying a Call)

7

• The Strategy: The trader is bullish but wants to protect themselves against a stock market crash.

• The Trade: Buy 1 RELIANCE Call Option with a Strike Price = ₹1310 by paying a upfront Premium = ₹30.35.

• Formula: If Expiry > Strike: Profit/Loss = (Expiry Price - Strike Price) - Premium Paid

• Formula: If Expiry <= Strike: Profit/Loss = -Premium Paid (Option expires worthless)

To simulate the bullish option strategy on the Opstra builder follow these configuration steps:

1. Select Segment: Change the first segment dropdown menu from Futures to Options.

2. Select Expiry: Ensure the next dropdown is set to the near-month contract, 28JUL2026.

3. Select Strike Price: Click the strike dropdown menu and select the 1310 strike price line.

4. Select Option Type: Choose CE (Call Option) from the final dropdown panel.

5. Set Direction & Quantity: Verify that the Buy button is selected and keep the Lot Qty. at 1 (controlling 500 shares).

   • Note: Notice that the system automatically captures a live benchmark Option Price (Premium) of 30.35, matching your setup parameters.

6. Click the blue "ADD POSITION" button to lock in the contract simulation.

Scroll down the webpage right below the configuration layout to verify the simulated portfolio metrics shown below:

• Active Position: You will see B 1x 28JUL2026 1310CE running at an entry premium of ₹30.35.

• Max Profit: The dashboard displays ₹ Undefined. This visually validates that if Reliance rallies aggressively past your strike, your profit potential is mathematically unlimited.

• Max Loss: Shows a fixed -₹15,175 (-100.00%). This represents the absolute maximum capital risk (). Unlike Futures, your loss is strictly capped even if the stock drops to zero.

• Breakeven Point: The system identifies at 1341.0 ().

• Estimated Margin/Premium: The box shows Shows ₹ +15,175. Remind students that option buyers pay only the fixed premium upfront; no structural exchange margin is blocked.

Look at the chart curve generated on your Opstra panel in image evaluate the capped-risk mechanics of buying a call option:

• The X-Axis (Horizontal — Underlying Price): Displays potential expiry prices for Reliance across a wide projection band from ₹993 to ₹1,608.

• The Y-Axis (Vertical — Profit/Loss): Maps out the net financial results in rupees, scaling above and below the horizontal bold zero line.

• The Flatline Floor Zone (Capped Risk on the Left): Look closely at the entire left-hand quadrant covering any price below the ₹1,310 strike. The chart line turns perfectly flat and remains locked inside the orange/red territory at exactly -₹15,175. This provides stark visual proof to students that even if Reliance crashes down toward ₹1,100 or ₹993, the buyer's losses completely stop growing.

• The Turn Point: The chart line bends upward precisely at the ₹1,310 strike price landmark, charting the point where the option contract begins to build intrinsic value.

• The Green Zone (Linear Profit on the Right): As the stock price rallies past your precise break-even line of ₹1,340.35 (moving right towards ₹1,362, ₹1,403, and up to ₹1,608), the payoff curve breaches the zero line, turns bright green, and shoots diagonally straight upward. This visualizes that once the upfront premium is covered, your profit potential scales dynamically alongside the rising stock price.

Long Put Option (Buying a Put)

8

• The Strategy: The trader is bearish and expects Reliance to fall, but wants fixed, limited risk.

• The Trade: Buy 1 RELIANCE Put Option with a Strike Price = ₹1,310 by paying an upfront Premium = ₹30.25.

• Formula: If Expiry < Strike: Profit/Loss = (Strike Price - Expiry Price) - Premium Paid

• Formula: If Expiry >= Strike: Profit/Loss = -Premium Paid (Option expires worthless)

• Observation: If Reliance drops sharply, the Put buyer earns substantial profits. If the stock rallies unexpectedly, the maximum possible loss is strictly limited to the ₹30.25 premium.

To simulate a protective bearish option strategy using the parameters shown in image below, follow these configuration steps:

1. Select Segment: Verify that the first segment dropdown menu is set to Options.

2. Select Expiry: Ensure the contract dropdown is set to the near-month expiry, 28JUL2026.

3. Select Strike Price: Click the strike dropdown menu and select the 1310 strike price line.

4. Select Option Type: Choose PE (Put Option) from the final dropdown panel.

5. Set Direction & Quantity: Verify that the Buy button is selected

6. Lot Qty. at 1 (controlling the standard bundle of 500 shares).

• Note: Notice that the system captures a live benchmark Option Price (Premium) of 30.25, matching your initial lab setup.

7. Click the blue "ADD POSITION" button to lock in this simulation on the platform.

Scroll down the webpage right below the configuration console to verify the simulated portfolio metrics shown below:

• Active Position: You will see B 1x 28JUL2026 1310PE running at an entry premium of ₹30.25.

• Max Profit: The dashboard displays ₹ Undefined. This reminds students that if Reliance experiences a heavy drop toward zero, the option captures massive, cascading returns.

• Max Loss: Shows a fixed capped value of -₹15,125 (-100.00%) (). Even if the stock rallies unexpectedly to infinity, the loss is strictly limited to this upfront premium.

• Breakevens: Plotted at 0-1279.0, meaning your profitable zone begins once the stock drops below ₹1,279.75 ().

• Estimated Margin/Premium: Shows ₹ +15,125, confirming no margin is required for option buyers.

Look at the mirrored asymmetrical chart curve generated next to your dashboard in image to visually evaluate the downside protection structure:

• The X-Axis (Horizontal — Underlying Price): Displays potential expiry prices for Reliance across a wide projection band from ₹993 to ₹1,608.

• The Y-Axis (Vertical — Profit/Loss): Maps out the net financial results in rupees, scaling above and below the horizontal bold zero line.

• The Flatline Floor Zone (Capped Risk on the Right): Look closely at the entire right-hand quadrant covering any price above the ₹1,310 strike. The chart line turns perfectly flat and remains locked inside the orange/red territory at exactly -₹15,125. This provides visual proof that even if Reliance rallies unexpectedly to ₹1,400, ₹1,500, or higher, the buyer's losses are strictly capped and will never exceed the upfront premium paid.

• The Turn Point: The chart line bends dynamically precisely at the ₹1,310 strike price landmark, mapping out the threshold where the put option begins to accumulate intrinsic value.

• The Green Zone (Linear Profit on the Left): As the stock price drops below your precise break-even line of ₹1,279.75 (moving left towards ₹1,239, ₹1,198, and lower), the payoff curve breaches the zero line, turns bright green, and shoots diagonally straight upward. This visualizes that a put option converts sharp market declines into substantial, expanding profits.
