In technical analysis, majority of the patterns were first observed visually and then the rules made. Observing this interesting phenomenon on BNF over the past one month.
Any strong up day on BNF is immediately followed by a gap down open from the previous closing

So any upmove /upday is almost never having any follow-up buying the next day. Unless this pattern gets broken by 1-3 days of upmove after a strong closing, BNF looks extremely bearish. The logic of BNF seems to be " will kick your ass if you take bullish positions overnight" 😀
Jokes apart, if you want to understand the logical basis of patterns, this book is still the best :

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)
