$ZEC |Daily MACD|Golden cross below the zero line
Before discussing capital flows, first understand MACD.
The same MACD settings mean different things on different timeframes: crossovers happen more often on the 4-hour chart and less often on longer timeframes, but they carry greater significance.
A crossover is only a signal in itself. Whether the price breaks above the most recent resistance level and whether trading volume confirms the move are often used for further validation.
All data summarizes past price movements, and the market may move in the opposite direction at any time.
