// The FVE is a pure volume indicator. Unlike most of the other indicators 
// (except OBV), price change doesn?t come into the equation for the FVE 
// (price is not multiplied by volume), but is only used to determine whether 
// money is flowing in or out of the stock. This is contrary to the current trend 
// in the design of modern money flow indicators. The author decided against a 
// price-volume indicator for the following reasons:
// - A pure volume indicator has more power to contradict.
// - The number of buyers or sellers (which is assessed by volume) will be the same, 
// regardless of the price fluctuation.
// - Price-volume indicators tend to spike excessively at breakouts or breakdowns.
// This study is an addition to FVE indicator. Indicator plots different-coloured volume 
// bars depending on volatility.
//
// You can change long to short in the Input Settings
// Please, use it only for learning or paper trading. Do not for real trading.
