Profit hunter adds three lines to your chart indicating different things. It gives you a trend line which is gold. If the price action is above it, this indicates a bullish or long trend. If the price action is below it, this indicates a bearish or short trend. The blue line in the screenshot below is called a ReEntry Touch line. It indicates a point of re-entry. The cyan/magenta line indicates a very short-term trend flip. It is called a ReEntry Verification line.
