Relative strength Index

The Relative Strength Index (RSI) is a key momentum indicator in cryptocurrency trading, crucial for identifying overbought or oversold conditions and assessing price movement strength.
The Relative Strength Index (RSI) is a popular and significant momentum oscillator in the crypto space. Oscillators are particularly useful for determining overbought or oversold conditions, trend reversals, and the strength of a price movement. Developed by J. Welles Wilder, the RSI aims to measure the momentum and shifts of price actions. It gives traders insights about whether an asset is overbought or oversold, which helps them identify potential trend reversals or continuations.
The RSI is calculated using the average gain and average loss over a predetermined time frame—typically 14 days. The formula is RSI = 100 - (100 / (1 + RS)), where RS (Relative Strength) is the average gain divided by the average loss.
On the RSI chart, the RSI indicator typically suggests an upward trend when it reaches 30 and a declining trend when it crosses 70. Generally speaking, an RSI score above 70 signals overbought conditions and suggests a possible reversal. An RSI value of 30 or lower signals oversold conditions and could be indicative of a rebound or a good time to buy.​​
A crossover of the RSI above 50 (Centerline) may suggest a change in momentum to the upward, while a crossover below 50 may suggest a change in momentum to the downward direction.
Divergence signals: A possible upward reversal is indicated by bullish divergence, which happens when the price forms a new low but the RSI does not confirm it. When the price reaches a new high but the RSI fails to support it, this is known as bearish divergence, and it points to a possible downward reversal.
There are also considerations and limitations: RSI can nevertheless generate false signals, just like any other indicator, particularly in volatile markets. Depending on the state of the market, the RSI's effectiveness may vary. For a better technical analysis, it is recommended to utilize this along with additional indicators.
