Trading Strategy Case Study #2

Capital Requirement: Rs. 85,000

Strategy used: Strangle - Range depends on Risk Appetite and expected ROI

Mechanism: This strategy is mainly for those traders who don’t have much time to track the market and want to deploy a long term strategy. The underlying assumption behind this strategy is that NIFTY 50 will be between 13,000 and 22,000 until December 2023 expiry i.e. 8 months from now. Sell the 13,000 PE (LTP 23.75) and 22,000 CE (LTP 29.45). You will receive a net premium of Rs. 2660 and would need a margin of Rs. 75,000. Over the capital of Rs. 75000 the ROI would be approximately 3.5%. This when annualized would be equal to 5.25%. But this seems to be too less, even lesser than the existing FD rates (~7.5-8.0%). Now here is the catch. Deploy Rs. 85000 into G-Secs (post 10% haircut, you will get Rs. 76000 around as cash equivalent collateral value) which are eligible for pledging, the effective ROI on the G-Secs would be around 7.5%. Now compute the total annual return of the strategy - 5.25% + 7.5% ~ 12.75%.

Many HNI investors and Traders have been using this strategy to gain alpha. Depending on your risk taking appetite, you can adjust your strikes.

Excellent strategy. One question here , a few months back there were issues with dhan for far months including just 3 months away.

Till how many far months it is allowed now ?

Playing devils advocate again. Pardon me for the same.

Wouldn’t the margin required increase with market movement on either side (which can be wild from MAY-DEC) ? So if someone just starts with 76000 after pledging just Rs.1000 is just not enough cushion.

@pavz for FO it is 270 days.

@t7support Definitely the margins would shoot up for any high volatility event. Since the legs are wider, the impact will be lesser comparatively. Having said this, trading in any option strategy is “risky”. It looks easier to deploy any strategy but “fire-fighting” skill is quite intuitive in any strategy.

Will be talking about strategies with absolutely ZERO risk - like the Short Box Spread / Long Box Spread and how “Banks” have an edge over this to fund their lending business later in this series.


This is a must have skill for this kind of option selling strategy. If you have a method to do so please share that also.


So, trade duration is 8 months to gain the max profit.

Hi @iamshrimohan ,

Does G-Sec offer 7.5% for 8 months or HTM?


Can you please explain what should the trader do after 8 months to G-sec?

In the example, it projects 12.75% ROI is made within 8 months, is this true?

Let’s also talk about Volatility, since it is the most important parameter to decide when to deploy funds into an options selling strategy.

Hope this information helps!!


Also @iamshrimohan how to search for gsec in Dhan ? What would be the symbol format ?

Hi @t7support

@t7support Firefighting strategies vary based on risk appetite and market experience, and there is no one-size-fits-all approach. Consequently, seasoned traders tend to focus on a single strategy and become experts in it rather than using multiple strategies.

Now for the strategy mentioned above, fire fighting can be done as: If the market moves sharply in one direction, traders can book profits on the other leg and wait for the market to consolidate. With the profits, they can either wait for further consolidation or purchase a hedge to limit losses on the extreme side. If capital permits, they can set up a new strangle with new strikes after consolidation.

Based on the deployment, the annualized ROI would be 5.25% for a duration of 8 months. However, there is a catch: if the premium erodes quickly and results in a better ROI within a few days or months, traders can opt to book their profits and switch to the next set of strikes. The goal of the trade is not to hold for the full 8 months but to generate alpha above the risk-free rate.

Excellent focus on detail - this is commonly referred to as “strategy optimization”. However, it’s worth noting that G-Sec payment frequency is semi-annual and interest payment dates may differ from security to security. Ideally, for this strategy, the G-Secs would pay interest twice within the 8-month cycle. It is commonly assumed that G-Secs or any underlying collateral with a fixed ROI will be held indefinitely.

@iamshrimohan ,

How much slippage trader should expect if he decides to sell G-Sec in the secondary market after 8 months?

On average what’s a normal spread in a 10Y G-Sec?

Also, in the example which G-Sec have you quoted - 1Y/5Y/10Y?

@amit G-Secs with good volume have a very low slippage (roughly around 0.02-0.05%) with around 1000 quantity

In the example I did not quote any specific G-Sec, it was generic.

thanks @iamshrimohan for answering the queries!!

I haven’t tried the in Dhan, but looks like specific G-Secs can have good liquidity.

@amit Liquidity is a matter of exchange. So on NSE / BSE / NDS-OM, the liquidity may vary. However, BSE and NSE would most likely have the same liquidity due to same participants. However in NDS-OM, only specific entities are allowed to bid and the minimum ticket size is Rs. 5 cr.

@iamshrimohan ,

Does exiting 10Y G-Sec before HTM have interest rate risk?

@amit Yes they do. An increase in interest rates can lead to a decrease in bond prices, and vice versa. This is due to the anticipation of new bonds being issued with higher yields, which makes existing bonds less appealing to investors. Nevertheless, if an investor holds a bond until it reaches maturity, the interest rate becomes irrelevant.
