Selling option...without knowing the level will be disaster....
Y'day....if anyone would have sold put options strike price starting from 11700 to 11900, thinking last day premium will be zero... screwed nicely....
You should know the level or trend pressure...before selling options...
Y'day put options moved from 3 to 70....... huge risk... so... learn and trade...otherwise, your pants will be on fire....
Hourly sequence change is more important on settlement days....y'day 1.30 sequence change established and put options moved like anything.....
Learn and trade..... option selling is a tough job without knowledge...
