ADX measures trend STRENGTH and says nothing about direction — 30 is a strong move that may be up or down. Below 20 the market is ranging, and trend-following rules tend to be chopped up there.
Here the reading entered a trending reading 4 times, with a median stay of 90 minutes and a longest of 205. ADX is the filter most strategies gate on, so how long it actually held above the threshold decides how many of a day's signals would have been allowed through at all.
