 * 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.
