Expected Move is the amount that an asset is predicted to increase or decrease from its current price, based on the current levels of volatility.

In this model, we assume asset price follows a log-normal distribution and the log return follows a normal distribution.
Note: Normal distribution is just an assumption, it’s not the real distribution of return
