Since IRONFLY is the flavour these days, sharing my own thread. It has GREEKS incorporated which automatically reduces wing size & risk.

P.S. No one specifically invented ironfly & it's adjustments. A good trader can figure it out on his own. I've been doing it on & off for yrs.

THREAD ON IRONFLY

These days the most preferred strategy for option sellers due to improved margins is IRONFLY. It's essentially a short straddle with long strangle. Long strangle acting as 'WINGS', which help in capping the unlimited risk associated with a short straddle.(1/n)

You can also view the position as a combination of Cal & Put credit spreads, if that makes it more easy for you.

There are 3 important things to understand while trading this strategy:

1) Initial size of the Wings
2) Risk Management
3) Adjustments

(2/n)

Since we are selling an ATM straddle, the 1st question is how far our wings should be? Ideally i sell .50 delta straddle & buy .20 or .10 OTM strangle, depending on my view on volatility. So the distance of wings depends on the IV setup. Higher the IVs, greater the distance.(3/n)

If you don't understand greeks, then ideally with 30 days to expiry (dte), wings should be around 300pts either side. If your trading in weekly then it should be not more than 200pts. Higher the premiums, higher the distance as we have more cushion of theta. (4/n)

It is important to understand that we need to reduce the distance of wings with time so as to manage our RISK in gap openings or sudden volatile move. So for eg. if you started with 300pt wings with 30dte, the wings wouldn't give the same protection when there is 7dte. (5/n)

Topic: Why triple straddle has no real benefit.

A triple straddle is essentially an ATM Straddle & one or two step away straddle on either side. The position is almost neutral strategy just like any other neutral straddle or strangle.

1/

We can also view the position as an ATM straddle, a strangle & inverted strangle.

For example

Nifty: 14700

Triple straddle: 14600,14700,14800

Another view:

14700 straddle
14800-14600: strangle
14600-14800: Inverted strangle

2/

So the real question is what is the advantage of an inverted strangle over it's otm counterpart?

The answer is none.

They both have same premiums/theta. Only that slippages will be high in inverted strangle when we do the required adjustments plus liquidity issue.

3/

So isn't it better that instead of a triple straddle, we can just do ATM Straddle & 2* OTM strangle.

So in the above eg. the position will be

14700 ATM straddle
2* 14800-14600 otm strangle.

Same premium received, similar range just that there's no nuisance of ITM options.

4/

The question arises:

Why trade in an ATM straddle & 2* OTM Strangles? Why over-complicate?

Options are in itself a complicated instrument. Wouldn't it be better to stick to one straddle or a strangle & adjust accordingly?

Lesser the strikes, more there will be clarity.

10 mistakes in my 14 years of trading as an option seller 🧵

1. Staying neutral all the time. Majority of the years i have been a neutral option seller. I now realise that having a little sense of direction would have given me an added advantage with better utilisation of capital & also leverage (till the time it was available).

2. Too much importance on adjustments. Initially like most of the new option sellers, i had this notion that i can perfect my adjustment skills for any market conditions. Ofcourse i was wrong. Market is supreme & we need to respect it at times.

3. Not giving importance to greeks. For initial 6 years i didn't even know the existence of greeks. Since i started using them, option selling has become rather less complicated on the contrary of what most people believe.

4. Having too much confidence on the certainty of theta decay. Enough is said about it already. Theta decay is not an edge.

My previous b'day which fell on expiry day was in 2010. On that day Nifty straddle opened at 45. Day range of nifty was around 30pts :)

(High 5415, Low 5380)

At that time:

•Didn't know the word Straddle though i used to trade them regularly
•Greeks existence wasn't known

•Adjustments felt like a superpower
•Everyday theta decay was a birth right
•Any strategy thought off felt like a personal invention
•Listening to people warning about unlimited loss in option selling was normal
•Making unlimited gain in long straddle seemed a possibility

•Volumes & Oi were closely tracked
•Overnight positions without hedge was a normal routine

All the above points have been changed over the years. But the underlying market psychology & following the price action still remains the same.

Thank you all for the warm wishes 🙏

AN ESSENTIAL THREAD ON OPTION ADJUSTMENTS

Adjustments can be done in variety of ways & depends totally at the discretion of the trader. To get a clear mind we need to know the following:

1) What to follow,
2) How to make the adjustment,
3) When to make the adjustment. (1/5)

1) We need a way to measure the imbalance created by a delta move in an option strategy. We can measure through premiums, distance from index or delta of greeks (i personally use delta). So basically whatever way of measure we use, both sides should be equal in it. (2/5)

2) Adjustment can either be done by selling extra quantity of profitable side, buying the quantity of losing side or shifting both the sides. I personally shift the sides because with extra quantities our Gamma gets imbalanced & the risk increases if market reverses. (3/5)

3) While the first 2pts are objective, when to make an adjustment is totally subjective. It can be fine tuned through experience. It also depends upon what strategy u are using. For a short strangle the adjustment required is faster than a ratio spread or an IC. (4/5)

Straddle/strangle require faster adjustments because they are more vulnerable to delta or IV spike. Any other strategies like ratio spreads, ironfly, butterfly have some bought option, which can negate the spikes for a while. So we need a defined system as to WHEN to adjust.(5/n)

Topic: HOW TO TRADE IN RISING PREMIUMS SCENARIO

Option sellers specially Straddle sellers feel that rising premiums give them excellent opportunity to make easy money. So what they are seeing is the theta aspect of options & ignoring the delta/gamma/vega forces.

1/

With rising premiums come high delta moves. There is a reason why premiums are all increasing up in the first place. High uncertainty & fear is what's controlling the markets during such times. So a volatile 200 point move in nifty is always on the cards.

2/

Adjusting during such delta moves involves high slippages. Such costs go in our system & are irrecoverable. So if the ATM straddle is around 400 & after 200 point downmove, the next straddle is at 450 & the loss is not just 50points but compounded much more.

3/

Also there are chances that there is no decay throughout the day. So a straddle seller has to take that heavy risk of carrying it forward & chances of gap openings are high during such times. If converted into Ironfly, then the cost of the wings is too expensive.

4/

Thus cutting down the initial credit significantly.

There will also be very few instances when premiums don't fall till expiry day. So with each delta move the cost of holding a straddle gets accumulated & pressure keeps mounting for the stubborn option sellers.
