RSI (Relative Strength Index)
An indicator from 0 to 100 showing whether a price has risen or fallen unusually strongly lately.
The RSI compares price gains with price losses over recent days, usually 14. Values below 30 are considered "oversold": the price has fallen hard in a short time. Values above 70 are considered "overbought".
Oversold does not mean the price will turn at once; in strong downtrends the RSI can stay low for a long time. It gets more interesting when the RSI climbs back out of the oversold zone. DipCatcher uses the RSI as one of several floor checks.
