More from Subhadip Nandy

The most important question now on the mind of all analysts and traders. Is this a bear market rally or is this the start of a bull move. Retweeting this as I will need a few tweets to explain my view


Everyone knows the HH-HL or LH-LL as per Dow theory. This can be a bit confusing on how one marks the Highs and Lows. Long back, I picked up this trick from one of the neo-Dow theorists on what to do in scenarios like this

Simply plot a 5 period exponential moving average on a different panel. A 5-EMA simply shows you a running weekly perspective and kind of smoothens the price where a single spike high/low is not of that much importance

You will see this 5-ema also making HH.HL.LH.LL. So now, rather than focusing on the highs/lows on the charts, focusing on highs/lows on the 5-ema gives a cleaner perspective

As per this charts, unless the 5-ema now closes above 17540 ( the ema, not Nifty price) I will not play this as a bull market. I will deal with this market as a counter move against the major bear trend
Ok here is the explanation. Grab a cup of coffee and read on. If you have not read/noticed this, you will see intraday options movement in a new light.


Say we have two options, one 50 delta ATM options and another 30 delta OTM option. Normally for a 100 point move, the ATM option will move 50 points and the OTM option will move 30 points. But in a high volatile environment, the OTM option will also move nearly 50 points

To understand why this happens, first understand why an ATM option is 50 delta. An ATM option has the probability of 50% of expiring as ITM. The price just has to close a rupee above the strike for the CE to be ITM and vice versa for PEs

Now think of a highly volatile day like today. If someone is asked where the BNF will close for the day or expiry, no one can answer. BNF can close freakin anywhere, That makes every option of an equal probability of being ITM. So all options have a 50% probability of being ITM

Hence, when a huge volatile move starts, all OTM options behave like ATM options. This phenomenon was first observed in the Black Monday crash of 1987 at Wall Street, which also gave rise to the volatility skew/smirk
IV - A thread

In financial mathematics, implied volatility of an option contract is
that value of the volatility of the underlying instrument which, when
input in an option pricing model ) will return a theoretical value equal to the current market price of the option (1/n)

Implied volatility, a forward-looking and subjective measure, differs
from historical volatility because the latter is calculated from known
past returns of a security. .

To understand where Implied Volatility stands in terms of the underlying, implied volatility rank is used to understand its implied volatility from a one year high and low IV.

(3/n)

Options traders are always looking at the IV and IVR/IVP. For option
buyers, a low IV environment is best to initiate positions as the
subsequent rise in IV actually helps their positions . Even if the IV
remains flat, the position is not hurt by volatility (4/n)

Option sellers on the other hand are looking for high IV scenarios, where
the subsequent fall in IV ( known a vol crush , most often seen after
earnings/events) helps their positions. Here also, if the IV does not
rise, it does not hurt a seller's positions (5/n)

A brief analysis and comparison of the CSS for Twitter's PWA vs Twitter's legacy desktop website. The difference is dramatic and I'll touch on some reasons why.

Legacy site *downloads* ~630 KB CSS per theme and writing direction.

6,769 rules
9,252 selectors
16.7k declarations
3,370 unique declarations
44 media queries
36 unique colors
50 unique background colors
46 unique font sizes
39 unique z-indices

PWA *incrementally generates* ~30 KB CSS that handles all themes and writing directions.

735 rules
740 selectors
757 declarations
730 unique declarations
0 media queries
11 unique colors
32 unique background colors
15 unique font sizes
7 unique z-indices

The legacy site's CSS is what happens when hundreds of people directly write CSS over many years. Specificity wars, redundancy, a house of cards that can't be fixed. The result is extremely inefficient and error-prone styling that punishes users and developers.

The PWA's CSS is generated on-demand by a JS framework that manages styles and outputs "atomic CSS". The framework can enforce strict constraints and perform optimisations, which is why the CSS is so much smaller and safer. Style conflicts and unbounded CSS growth are avoided.
