Technical Note | $JCT | 4-hour MACD | Bearish crossover above the zero line
First, a definition: The height of the histogram bars reflects the distance between DIF and DEA. Bars growing taller one after another indicate that the current trend is gaining strength, while shorter bars indicate that it is weakening.
A common interpretation: The crossover itself is only a signal. Whether the price can break through the nearest resistance level and whether trading volume confirms the move are often used for further validation.
Cross-checking multiple indicators is more reliable than relying on just one, but even more indicators cannot provide a definitive answer.
