Here is a quick example of why I like using the Hull MACD in conjunction with the normal MACD. Here we see clear divergence with the Hull MACD and the normal MACD going in opposite directions. This lets us know that this uptrend is weak to begin with. The price action for the time frame shows this, with prices having a fairly strong ceiling. It seems we lanced through the ceiling and that has taken most of the strength out of the bulls for now.
No trading system is perfect but this is one pattern I have noticed for the short while I have been integrating the hull MACD into my system. Additionally, we see the Stocastic RSI is dropping swiftly and the RSI had a relative high a few hours ago. More likely than not (which is why this isn't financial advice) we will see convergence on the hourly normal MACD and another leg down.
