Internals may be used to identify range days as price action is being evolved. Spreads usually may have a divergence in top and bottom indicating no clear direction. TICKS will also hit 600 and -600 in succession indicating lack of market direction. Price may continue to drift in one direction with low volatility during such days or rotate around PVP / VWAP.

TICKS made 600 and -600 with each peak. Eventually pullbacks got shallower and price had a slight upside.
ES was range-bound in the morning and gradually drifted higher in the afternoon. Eventual upside bias was obvious from internals.
