## Comment on Theta

Nifty Spot = 10760

CE 10850 Premium = 83

CE 10900 premium = 65

Both intrinsic value is 0 but time value has a difference of 18 rs. How to arrive at this 83 and 65 rs time value ?

So like delta of atm options is always around 0.5 what is the formula for calculating time value ?
