Review/Improve Introduction to Options Tutorial

[AlexCatarino]

In the Historical Volatility and Implied Volatility Tutorial, for example, there is no documentation for the variables of the method:

def bsm_price(option_type, sigma, s, k, r, T, q):
    pass

what is q?

Also, we should be able to run it in Research with QuantConnect data.

Currently, some tutorials are relying on external data and libraries, e.g. Options package in Volatility Skew. In this case Options is no longer available.

Review: "The Value of Options"

TimeValue = Premium - IntrinsicValue
-7 = 10 - 17

The premium must be higher than the intrinsic value or the time value would be negative.
