Force Index

This study calculates and displays the Force Index for the Price and Volume data.

Let \(C\) and \(V\) be random variables denoting the Closing Price and Volume, respectively, and let their respective values at Index \(t\) be denoted as \(C_t\) and \(V_t\). Then we denote the Force Index at Index \(t\) as \(FI_t\), and we compute its value for \(t > 0\) as follows.

\(FI_t = V_t(C_t - C_{t - 1})\)
