Damiani volameter

The Damiani Volameter is another trend and range filter. When the black line is above the green line, it shows that the market is ranging. When the green line is above the black line, the market is trending. The indicator does not display which direction the market is trending, thus, you might need to add another directional indicator like momentum, to make it a complete trading system.

How to use it? suggestion it just purely to filter the ranging market from the trending market. Like most range and trend filters, the challenge is to know when the range market is ending and when the new trend is starting, vice versa.

Trending market = use trend strategies (moving average cross, etc)

Range market = use range strategies (stochastics, oscillators)
