// @description Stochastic Momentum Index (SMI) of Money Flow Index (MFI).
// The Stochastic Momentum Index (SMI) is a technical analysis indicator that uses the difference between the current
// closing price and the high or low price over a specific time period to measure price momentum. On the other hand,
// the Money Flow Index (MFI) is an indicator that uses volume and price to measure buying and selling pressure.
// When these two indicators are combined, they can provide a more comprehensive view of price direction and market strength.
