Note how AAPL lost the progression of blue triangles prior to the recent decline from the 131 area.
There are numerous ways to look at these triangles, but what I want to show is the DAYS when AAPL is outperforming the market so I can see at what levels people were in the market BUYING AAPL shares in a relatively unusual way relative to the market in general. That, to me, is what KEY HIDDEN LEVELS ARE ALL ABOUT. We can use REAL NEWS, as in my Key Hidden Level, or we can use RELATIVE price action to show where the important price levels are in a stock.
So, closely examine the BLUE TRIANGLES in the chart so you can see the days when AAPL stock was UP when VIXY was ALSO UP. It provides VERY USEFUL levels.
