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

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)

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 🙏

@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.

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.

A thread about STBT options selling,

The purpose is simple to capture overnight theta decay,

Generally, ppl sell ATM straddle with hedge or sell naked options,

But I am using Today’s price action for selling options in STBT,

(1/n)

Its work on both index (Nifty, BNF) as well some standard stock but i used only for Index on every day and Last 10 days monthly expiry i do in stocks only specific,

It’s purely STBT type’s trade sell today and buy tomorrow kind,

(2/n)

Let’s start the strategy,

Every day at 3:15 PM, Open Nifty or BNF chart in daily TF.

See the last candle formation only; we take trade always based on the last candle formation

(3/n)

Case 1:
If Red Bearish candle formation, Mark the high and low of that candle

High 35979, Low 35667. (16th July)

Based on this candle we simply sell credit call spared (Sell 36000 CE and Buy 36300CE) you can make the difference between two calls 300 or 400 as per your risk,

Case 2:
Bullish strong candle

High 35238 and low 34922 (5th July) (Refer the image)

Based on this candle we sell credit put spread (Sell 34900 Put and buy 34600 put)

In this session we talked about
1. Basics of Option Selling
2. Directional Vs Non Directional
3. Straddle and Strangle Backtest
4. Benefits of Automated
