Above you will see the Madrid Moving Average Ribbon utilized.
The first (lag-confirmed) downtrend warning signal was strong, but took time to confirm. The second was moderate and also took time to confirm. The third was what led to our actual short-term reversal. This 3rd warning signal was moderate, but confirmed shortly after occurring. This illustrates a material drop off in buyside support, indicating that investors are wary of a strong correction.
I believe this dramatic drop off in volume and categorical short-term trend reversal will continue deeper. The warnings are (and were) all there, including the lack of any material higher highs on the daily chart.
