U guys stopped ? Am still waiting from the past 8 hours. 
I forgot what I already knew. 
I have made my point. Nothing more to add… 
It’s wasn’t nonsense. Everybody has their point of view. It’s all good. 
"Todays event show us a snapshot of how price discovery happens in stock market ,where all participants fight the market with their own point of view "
Doubts has been casted previously in this forum on whether I exist physically in this world. Someone implied that I may have a virtual existence inside coupled pieces of semiconductor chips aided by self aware snippets of code… 
Not a problem at all… 
Yeah very clearly , but still facing losses. None of them dissolving any tips where the market is headed next. 
no one really knows where its headed 
Option pricing basically involves price discovery in market place. To simply the B&S model premium is nothing by spot price minus forward price adjusted for probability. For people to trade in naked options (only buying or selling options) option delta can also be seen as probability of option and extent to which the price can move with respect to underlaying. To give an example if say delta 60 and this can be interpretation as there is 60% probability of movement of underlying vis a vis spot price. Theta is the more important option greek and related to time decay. Theta favours option sellers. we can disintegrate option price in terms of time value and intrinsic value. Lesser the time value and more the intrinsic value it is better. Many a times the market moves sideways and a option buyer is at disadvantage because he has to the right in predicting direction as well as speed. In a rangy market naked option seller can make more money. For a beginner theta and delta are the two most important greeks.

Yeah , I am understand a little better now , all the greeks are a descriptive stats or probality of the changes in price of options.
I’ll look in my point of view(Retail). upto my knowledge, could be wrong.
You enter a trade lets say 18700 PE shorting at 65, in next 30 mins Nifty moves up 50 points, by this time 18700PE value is 45. You wanted to know why it is 45 and not 30 or 50 or anything else, and who decides this
I choose 18700PE as this is the most traded nifty contract today. 56L+ contracts.
There are few people, they are called in various names such has FII, Prop desk, smart money and so on. Out of these 56L contracts they are the majority, let say 75% and remaining is retail(us). They use a system called HFT(High Frequency Trading). Their HFT system fires orders which includes option greeks too.(which model they use i leave it to you to find out). so based on Spot/fut price their system place orders w.r.t to option greeks. So one cannot manipulate option price because of this much liquidity.
We retail don’t have such automated system or super power to calculate within seconds,( still useless when we don’t know which side market will move in next candle and so on), so we just follow the option price and trade.
I really don’t know what others think or how they trade. Everyone has their own perceptions and thoughts. This is mine.
