The relative strength index (RSI) is a momentum indicator used in technical analysis that measures the magnitude of recent price changes to evaluate overbought or oversold conditions in the price of a stock or other asset.
So what happens at level 100? What happens if rsi is 100?
As you can see in the doge coin chart below, Rsi saw the 98 level and saw a correction from there. This 7-week correction pulled Rsi to 66 level and dragged it up again. (P.s. The chart is a 1-week candlestick chart..)
