To judge Ripple (XRP) trend changes using the MACD indicator, focus on crossovers, divergences, and the histogram. The MACD consists of the MACD line (12-period EMA minus 26-period EMA), the signal line (9-period EMA of MACD), and the histogram (difference between the two). A bullish trend is signaled when the MACD line crosses above the signal line, suggesting a potential price rise. A bearish trend emerges when it crosses below, indicating a possible decline. Bullish divergence (price hits a new low, MACD doesn’t) hints at an upward reversal, while bearish divergence (price hits a new high, MACD doesn’t) suggests a downturn. The histogram shows momentum: growing bars mean strengthening trends, shrinking bars signal weakening momentum. Confirm signals with price action on platforms like TradingView for accuracy.
