In trading, whenever the RSI is over 50, the momentum is positive, and the price will likely increase or continue increasing. Contrarily, when the RSI is under 50, it shows that the security is losing momentum, and the price is likely to decrease or continue decreasing. Of course, the further we go out of the equilibrium point, the trend reversal becomes more obvious to happen. For example, during an uptrend, the RSI is likely to stay above 30 and should frequently hit 70. On the other hand, during a downtrend, it is rare to see the RSI exceed 70; instead, the indicator frequently hits 30 or below.

If the average of U values is maximal, so that the average of D values is zero, then the RS value diverges to infinity, while the RSI is 100. The RSI is displayed as an oscillator (a line graph) on a scale of zero to 100. Welles Wilder Jr. and introduced in his seminal 1978 book, New Concepts in Technical Trading Systems.
