Pro Go

This indicator is composed of two lines, one green called “Public Buy” and one red called “Professional Buy”. The creator, Larry Williams, starts from the assumption that there is a substantial difference between the purchases of small investors (Public Buy) and strong hands (Professional Buy).

The interpretation is very simple, the line that crosses the other one provides the signal. So when the red line crosses upward the green is a bearish signal, on the contrary when the green line crosses the red line upwards the signal is bullish.
