/**
 * Money Flow Index
 *
 * @see https://www.investopedia.com/terms/m/mfi.asp
 *
 * What is the 'Money Flow Index - MFI'
 * 
 * The money flow index (MFI) is a momentum indicator that measures the inflow and 
 * outflow of money into a security over a specific period of time. The MFI uses a 
 * stock's price and volume to measure trading pressure. Because the MFI adds trading 
 * volume to the relative strength index (RSI), it's sometimes referred to as volume-weighted RSI.
