Options stratergy ( IV EFFECT )

I use opstra for option stratergies.

1.While with experimention, Implied volatility ( IV ) % change is an option imbibed in the software. What it is exactly. I know what is IV , but what is iv % change???

  1. And do IV change % will tend to zero at expiry ?

  2. How to calculate maximum possible loss in an option stratergy , irrespective of change in IV ( % ). Can we take the maximum possible loss at expiry is at IV % = 0?? ( irrespective of volatility before expiry )

  1. when you slide iv % , you will get appropriate premium for that iv value , ie , say for same stock price , same strike price , same days to expiry , if you input higher iv % then premiums will be higher and if you input iv % lower then will get premium lower for the same .

" Be Sensibull " youtube videos regarding option greeks would be helpful .

Bro. I have a question. The slide what we have is that represents the change in IV?. So take for example if we slide the IV to 20 % . So is that means the change of positive 20% IV from the date of taking position ?

say if iv was 15 for the option at the time when you sold , if you slide it to 20 % , then the iv for that option would be 18 , so you will get how much premuim would be increased ,
