I suggest to you, in order to understand the ADX divergences better, to attach the indicator on your preferred symbol, change the MA type to Simple and the MA periods to 1, so you can see the all the divergences more clearly.
A somewhat simplified way to interpret divergences:
If the price action has an upwards trend, you will mostly see hidden bullish and regular bearish divergences. Ideally, the hidden bullish will bounce the price to the upper rising channel, and the regular bearish to the lower rising channel, creating higher lows and higher highs.
Likewise, in a downward price action, you will see hidden bearish and regular bullish divergences. The hidden bearish will drop price to the lower downwards channel and the regular bullish to the upper downwards channel, creating lower highs and lower lows.
Regular divergences occur on a lower low (bullish) or a higher high (bearish). This usually means that a bounce/drop will happen, but you never know if the bounce/drop will be strong enough to change the trend.
Don't forget, that the ADX mainly gets its values from highs and lows, so the lower low in the price that made the regular bullish divergence might come together with some form of support, the price bounces hard enough and breaks the downward trend.
As always, how to trade these signals it's up to you.
