Jade Lizard Strategy: Expiry Payoff and Downside Risk

What a Jade Lizard Actually Is

A jade lizard sells an out-of-the-money put, whose strike is below the current underlying price, and a call credit spread: a sold call paired with a bought call at a higher strike. Each option is a leg. All legs use the same underlying, expiry and quantity, for net credit, the premium received after paying for protection. The put leaves large downside exposure.

Compare the total net credit per unit with the call-spread width. This is a gross expiry-payoff comparison, not a guarantee about an early exit or a complete after-cost result.

Time decay and falling implied volatility can benefit a short-premium position, other inputs unchanged. They do not establish a profitable result or offset every adverse underlying move.

What the No Upside Risk Label Actually Covers

When total credit per unit is at least the long-call strike minus short-call strike, gross expiry payoff above the long-call strike is non-negative. Subtract the width from the total credit once; do not add the put premium again.

A long call caps the call-spread expiry loss. The short put remains exposed to a falling underlying, and the account still needs margin. Early leg exits can remove the intended protection.

When the credit is smaller than the call spread width

The credit-versus-width rule decides whether the upside side has any expiry loss. Use the same made-up Nifty legs and quantity of 65, but change the premiums. The short 22,300 call is sold for 50 and the long 22,400 call is bought for 40. The 21,700 put still collects 90. Total credit is 90 + 50 − 40 = 100, equal to the 100-point width, so the gross expiry result above 22,400 is zero before charges.

If the put brings in only 80, total credit is 80 + 50 − 40 = 90. Above 22,400 the gross expiry loss is (100 − 90) × 65 = ₹650. The position then has a loss on both sides, so it no longer fits the usual no-upside-risk description. All premiums here are assumed for the arithmetic and are not quotes.

Worked Nifty Example With Assumed Strikes and Premiums

Illustrative Nifty monthly example with spot assumed at 22,000 and quantity 65 per leg. All strikes, premiums and expiry outcomes are made up for payoff arithmetic.

• Sell 1 Nifty 21,700 put at 90 points (collect 90).
• Sell 1 Nifty 22,300 call at 70 points (collect 70).
• Buy 1 Nifty 22,400 call at 40 points (pay 40).

Total credit per unit is 90 + 70 - 40 = 120. Call width is 22,400 - 22,300 = 100. For quantity 65, total credit is Rs 7,800. This is premium cash flow, not unrestricted withdrawable profit; margin is still required.

Between the short put at 21,700 and short call at 22,300, inclusive, gross expiry profit is Rs 7,800. Above 22,400, inclusive, gross profit is (120 - 100) x 65 = Rs 1,300 before charges. A closing transaction before expiry need not match this diagram.

Expiry Payoff Across Rising and Falling Prices

The table assumes all legs remain matched through cash-settled expiry. Values exclude every charge and any hedge or adjustment transaction.

At the example expiry of 21,000, put intrinsic value is 700 per unit. After the 120 credit, gross loss is 580 per unit, or Rs 37,700. The downside is much larger than the gross credit.

Downside Breakeven and Maximum Gross Loss

Example downside breakeven is 21,700 - 120 = 21,580 before charges. Below it, the fixed-leg gross expiry loss grows as the index falls.

If the index reached zero at expiry, maximum gross loss in this example would be (21,700 - 120) x 65 = Rs 14,02,700. NSE index options are cash settled; they do not deliver bank or index-constituent shares.

• The put remains unhedged on the downside.
• Required margin is not the maximum loss.
• A gap can make an intended stop unavailable.
• Changing a leg requires a fresh payoff and cost calculation.

What changes if you add a long put

A trader worried about the large downside can buy a lower-strike put. Take the first example and add a long 21,400 put at an assumed 30. Total credit becomes 120 − 30 = 90 per unit. That is 10 points less than the 100-point call width, so the structure now has a gross expiry loss on both sides. It is an iron condor: a short put spread, a short call spread and a defined range.

• Put spread width is 21,700 − 21,400 = 300 points.
• Worst gross downside is (300 − 90) × 65 = ₹13,650, reached at or below 21,400.
• Worst gross upside is (100 − 90) × 65 = ₹650, reached at or above 22,400.
• Best gross result is 90 × 65 = ₹5,850, between 21,700 and 22,300.

The protective put trades some credit for a cap on the loss. It also adds a leg, so there is one more charge on entry and one more on exit. Whether the trade-off suits you is a risk decision for you to make, and this page does not rank it.

Margins, Costs and Indian Taxes You Must Budget For

Current margin depends on the exact portfolio, volatility and broker requirements. No fixed per-lot range is verified here. Funds can be required while the position is open.

From 1 April 2026, sold option premium attracts seller STT of 0.15%. Exercise STT is paid by the purchaser on bought options exercised; do not automatically add it to a short-put seller. Other charges and any closing trades must also be included.

Ask a qualified chartered accountant about income-tax reporting and deductions. A payoff diagram does not settle filing or loss-carry-forward rules.

Event Risk and Monitoring Requirements

High premiums do not establish a favourable entry. An event can cause an adverse move larger than the collected credit, and volatility can increase further.

Record event timing and the monitoring demands before comparing contracts. No fixed delta, expiry window or profit-taking percentage is shown here to improve results.

Short put exposure and why the position needs monitoring

A short put gains when the underlying stays above its strike, and it loses roughly point for point as the underlying falls below the strike at expiry. A jade lizard keeps this risk. The call spread only changes what happens on the upside. Sources that teach the strategy describe the downside as large and the maximum profit as the credit collected, and give the downside breakeven as the put strike minus the total credit.

In the main example the breakeven is 21,700 − 120 = 21,580. A sharp fall can pass it between two checks of your screen, and an exit order placed as a stop is not guaranteed to fill near its trigger in a gap. Plan the size of the position so that a loss at your worst assumed level does not force you to close other positions or add funds in a hurry.

Which markets and expiries to look at

The worked example uses Nifty with a lot of 65 units, the lot size in OneTradeJournal's verified list (checked 28 Oct 2026). Lot sizes change, so confirm the current value on NSE before you calculate anything. Index options on NSE are cash settled according to NSE Clearing, so the legs settle in rupees and do not turn into shares. Check each contract's page for the current wording.

The strategy needs three liquid strikes on the same expiry. Wide quotes make the combined credit uncertain, because each leg is filled at a different price. Compare the credit you expect with the credit you actually received and write the gap in your notes.

How to record a jade lizard in a trade journal

A three-leg position is easy to log wrongly. Decide in advance how you will record it. OneTradeJournal is a manual journal, so you enter each trade yourself. Whatever tool you use, keep these fields together:

• The three strikes, the expiry, the quantity per leg and the premium for each leg at entry.
• Total credit per unit and the call width, with the difference written out.
• Downside breakeven and the largest gross loss you accepted before entering.
• The reason for the trade, your planned exit and the amount of money you set aside for margin.
• Any change after entry: closed leg, roll or hedge, with the new numbers.
• Charges for every leg, entry and exit, so the net result is not guessed.

Review them after the expiry. Did the credit cover the width? Did you follow the exit plan? Was the loss, if any, inside what you wrote down at entry? Those answers teach more than the profit or loss figure alone.

Jade Lizard Versus Similar Strategies

A short strangle lacks the higher-strike call protection. An iron condor also adds a protective put. Compare actual strikes and premiums; strategy names cannot rank the credit or suitability.

The call spread is not free. Its net credit and bounded expiry liability are part of the combined structure, and additional executions carry costs.

Managing and Adjusting the Trade

Rolling closes an existing leg and opens another, possibly with a realised loss and a different expiry. It does not erase the loss or guarantee a new credit.

Keep a written exit and funding plan. Gross upside protection at expiry does not remove interim losses from changing option prices, transaction costs or risks from mismatched and partially closed legs.

• Record each leg, expiry and quantity.
• Recalculate after any change to a strike or premium.
• Include charges in the credit-versus-width comparison.
• Review realised losses together with the new position after a roll.
