# Volume

> "It takes volume to make prices move." — Charles Dow

Volume is the fuel of the market. Price tells you *what* happened; volume tells you *how hard* the market worked to make it happen.

In a world of algorithmic trading and dark pools, volume analysis is the only way to see where the money is actually flowing. These indicators don't just track shares traded; they track conviction.
