FINDING EDGE IN OPTIONS

24/08/15: Nifty gap down 250 points & another 250 after that. Previous few months return gone, but since I'm quick to take my losses, was saved from ruin. Before that my only edge in option selling was adjustments & my forever edge of following PA. (1/n)

I soon realised that theta decay with sound adjustments is not an edge, which i earlier thought was & which gave me good returns over the years. After that i went deeper in understanding volatility behaviour, how/where it manifests & all the discrepancies in option chain. (2/n)

With finding edge in logistics i mean how to keep the greeks in check, SL in place & optimum ways of adjustments with minimum slippages. So the main aim here is to write theta without following vol behaviour & having any actual knowledge of what's going on in the markets. (3/n)

A dedicated trader can learn all this in few years & it is something which is 'obvious' to become successful. But majority can't reach this level, as this also requires consistent hustle in live markets. All the seminar/webinar business teaches you till this level only.(4/n)

If you get passed this level though, the real work starts, when you have to find your real edge. This can't be taught in a webinar. It needs serious introspection of your trading skills, psychology & strategies in use, which ultimately allow you to book excellent profits. (5/n)

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)

@javia_savan You answered it yourself 🙂
Adjustment cost is way too high for bnf. Sometimes bnf does exceed nifty in vol crush, but nifty overall is more consistent.

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.

THREAD ON DELTA (The most important GREEK)

Many traders don't indulge in understanding GREEKS because they think they are very complicated.

There are 4 primary greeks:

Delta
Gamma
Theta
Vega

In my experience, understanding DELTA is enough to take benefit of greeks.(1/n)

Delta measures the rate of change of options price based on the directional movement of the underlying.

So this means we can know in advance (theoretically) how much an option will move with the underlying & so we can prepare our strategies accordingly. (2/n)

Value of delta varies between 0 & 1 for calls and -1 & 0 for puts. This figure tells how much an option price will change, when the underlying moves 1 point. So example a delta of .2 of call indicates that for every 1 point change in the underlying, the price will move .2 (3/n)

For option writers who want to trade in neutral strategies like straddle, strangle, ratios, calendar etc, delta can be very helpful. So be it any complex strategy, knowing the NET DELTA can give you an idea of how your strategy will perform in different scenarios. (4/n)

Net delta is just the sum of the deltas of all the bull options (call+ & put-) minus the bear options (call- & put+).

So if we can track this, we will always be in the know of how much exposed our position is. It makes it easier then to adjust our position. (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.

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)

Understanding HIGH & LOW VIX

VIX at 16: If you check today's IV behaviour, they were not spiking much even with decent delta move in BNF. The movement was subtle, giving some time to adjust. So someone having good adjustment mechanism can stay in the game longer.

1/

VIX at 20: The same delta move will be more fierce, coupled with rise in premiums. When premiums rise with movement, then the adjustment cost increases exponentially. The premiums can fall back at EOD, but the damage is done if caught in the spike.

2/

After talking to few traders, their backtest result was in favor of high VIX of 2020, rather than 2017-19. The key flaw in the backtest were the adjustments which are not easy to calculate. Combination of high theta & fixed SL during high VIX, the IV crush is cashed at EOD.

3/

Neutral option sellers who don't adjust & have fixed SL on a static straddle will not be able to benefit highly in low VIX. The straddle which moves away from ATM will increase no matter what. But if we keep on rolling our strikes, then we get good realisation of theta.

4/

I have made majority of my profits in option selling when VIX was at 13-15, mostly just relying on my adjustments. Since 2020 with high VIX, adjustments stopped working because of increase in the frequency of delta + IV spike combos & so had to shift to directional trading.

5/

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 🙏

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.

Q: Sir why call option premiums are higher the put?

A: It usually happens when there is big difference between spot & future.

Example

BN Spot: 35110
BN Future: 35300
BN Synthetic Future: 35150

It depends on our perception of what is ATM & accordingly match the calls & puts.
