Have been following you for a while and your content has been great. I think if you made a video showing how the greek's sensitivity changes as time approaches the options maturity date would make for an interesting video. It would provide more intuitive reasoning as to how/how much the greeks change over time.
Is is possible to calculate the option Greeks, with just the following inputs: stock price, strike, option price, days till exp, risk free rate, dividend payment? If it is possible can you please make a video showing how to do this in Excel. Thank you in advance!
