Explain the Relative Strength Index (RSI) and Its Use in Identifying Overbought Conditions.
The RSI is a momentum oscillator that measures the speed and change of price movements. It oscillates between 0 and 100.
A reading above 70 typically indicates that an asset is 'overbought', meaning the price may be too high and due for a correction or reversal. In a pump and dump, the RSI often spikes rapidly above 80 or 90, signaling an unsustainable buying frenzy.
