In classics, the Relative Strength Index is described as "A price-following oscillator, which ranges from 0 to 100 and signalizes about market tendency to change the trend when RSI is high (close to 100%) or low (close to 0%)". When the index goes above the upper auxiliary line, bulls power is high, but the market is overbought and ready to enter into selling stage. Vice versa, when RSI goes below the lower auxiliary line, bears power is high, but it should be noticed that the market is oversold and the buying process begins.
