When two related components move in the opposite direction, it is called divergence. Divergence is one powerful trading concept, which determines the trend direction and provide hidden signal for future trend. Traders generally use divergence for two purposes; assessing the price action & trend reversal. For positive or bullish divergence, the price action moves lower lows and the indicator that tracks this action indicates higher lows. Conversely, for negative or bearish divergence, the price action moves higher highs and the indicator that tracks this action indicates lower highs.
