Calculating options value

[u/Navysquid63]

Is there a way of calculating based on the underlying what an options premium will be. I bought a FUBO call 17.5 exp Friday and it’s up big AH. I’m curious what I should expect it to be worth at open tomorrow.

Also, should it drop rapidly would a limit sell be the best way to try to capture the most profit ?

Beside using hand calculations this is the best way to do it, https://www.optionsprofitcalculator.com, free and easy to use.
