In total, there are four types of divergences : two bullish ones (regular and hidden) and two bearish ones (regular and hidden). To avoid getting confused when identifying divergences, I created the following basic rules :
Rule A
Price / oscillator Highs must be compared in Uptrends to discover Regular divergences.
Price / oscillator Lows must be compared in Downtrends to discover Regular divergences.
Rule B
Price / oscillator Lows must be compared in Uptrends to discover Hidden divergences.
Price / oscillator Highs must be compared in Downtrends to discover Hidden divergences.
Rule C
Regular divergences rely on the Oscillator divergence line to indicate the future trend Direction.
Rule D
Hidden divergences rely on the Price divergence line to indicate the future trend Direction.
Rule E
Always compare price Highs with oscillator Highs and price Lows with oscillator Lows.
