The concept of market inertia (that price tends to keep doing what it is doing at least for a little while longer) is the element that has a directional predictive value about it when is combined cognizance of the overall context that is being created and played out by the institutions. Their footprints are in the chart. They cannot hide what they are doing. They move the markets. The catch is that there are bullish and bearish institutions at all moments. The task becomes to determine which ones are winning and jump in on the inertia they create.
