Finite Volume Elements (FVE) Backtest

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.
