SPX; less and less price action

To start off with some context, the previous upper cycle, peak to peak, was 7 years. This cycle has lasted 10 years, roughly. We can then expect an obvious deeper recession. The last one was roughly 2 years long. But when? The market keeps expanding, the dollar has become stronger, oil is getting cheaper, and manufacturing is up. All the fundamentals look pretty good, aside from the fact that we are 3 years due for a peak. There's one weakness, technically that I can see right now. Price action is reducing and the VIX is at an all time low.
See the chart for the decrease in average true range as the SPX moves higher. Could this slow us down? Relative strength keeps building, positive. Food for thought.
