The price action for $XRP and bitcoin ($BTC) resembles a tightly compressed spring on the verge of uncoiling with a sudden release of energy.
That's the message from a key volatility indicator called Bollinger Bandwidth. Bollinger Bands are volatility bands set at plus two and minus two standard deviations above and below the 20-period moving average (SMA) of an asset's market price. The bandwidth measures the space between these bands as a percentage of the 20-day moving average.
In the case of $XRP, the Bollinger bandwidth has narrowed to its lowest level since October 2024 on the 4-hour chart, where each candle represents price action for a four-hour period. The 4-hour chart interval is quite popular in the 24/7 crypto market, allowing traders to analyze and predict short-term price movements. Bitcoin's 4-hour chart mirrors the Bollinger bandwidth pattern in $XRP.
