I want to test the same input variables below using BSM and CRR Binomial tree and compare the outcomes. I am finding it difficult to get the input

1. Continuous compounding Risk-free interest rate (r)

2. The volatility (Sigma)

3. The time until expiration (years) (T)

4. Option strike price (Per share). (K)

5. Underlying price of share: the current market price per stock. (S)

I will appreciate any information that can help.

thanks
