What is RSI?
The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and change of price movements, which was developed by J. Welles Wilder.
Many people use RSI to understand overbought and oversold state of market but during strong trending moves prices can remain in strong overbought region or oversold region for extended period of time. It therefore become necessary to see if market is in a trending mode or a trading range.
We use RSI along with Elliott wave counts to majorly determine positive or negative divergences between prices and indicator. Whether you use RSI, ROC, MACD, etc most of the indicators will essentially give similar output. Unless you are an expert one can rely on 14 periodicity. A period should be ideally selected based on Time Cycles.
Divergences: A positive divergence occurs when prices make lower low but RSI makes higher low and a negative divergence occurs when prices make higher high but RSI makes lower high thereby indicating the up move is on less momentum and the strength is waning out.
