where did you find the data for equation, especially the volalility?

I love it that you have a gamer's channel name

if probability of option being exercised increases, the value of that option decreases.. that does not sound right, does it...(?)

@alisleiman3103

Dear Bionic ,
is it possible to receive your Xlx Sheet. I am in the middle of course  that would be helpful

@riverallen1571

Do you have any opinions on using delta as an approximation to probability of in the money?

@Alexander-pk1tu

thank you sir! I liked your video very much.

@speisequark2

Thank you so much! Your video helped me a lot!

@speisequark2

Is it ok to use a negative riskfree rate r in that model?

@katienorris8341

Thanks, this is a great explanation! Very helpful

@etenat8772

amazing explanation

@indradipbanerjee4013

Should the stock be assumed to grow at the risk free rate or should the baseline be growth at cost of equity rate?

@jiaminzhu406

Great explanation.  I'm still a bit confused with N(d1), when you say the underwater price is counted as zero. 
If I denote p1 = N(d1) and p2=N(d2),  and forget assume q and r are both zero,  is it true that Sp1 = (S-K)p2 + K ?

@lawjef

I know you de-emphasized it in the sheet (denoted by the light grey font) but the "d2" formula is technically incorrect. The part on the far right "d1 - sigma * sqrt(T)" is correct, but the formula to the left of it should be "[formula that is already there] - sigma * sqrt(T)"
