Measures the appetite for buying and selling on a 0 to 1 scale by asking how far each bar's high and low extend beyond the prior bar. Tom DeMark's oscillator catches the fading drive to make new highs before price actually turns.
The DeMarker (DeM) is an oscillator devised by the technical analyst Tom DeMark.
Where many oscillators track changes in the close, the DeMarker looks at the high and the low.
How far did today's high extend beyond the prior bar's high? How far did today's low fall below the prior bar's low? Comparing the two, it expresses which appetite is winning, buying or selling, as a single line between 0 and 1.
Above 0.7, buyers are reaching for new highs one after another, an overheated zone. Below 0.3, sellers keep pressing to new lows.
The aim of the DeMarker is to catch the moment when the drive to reach for new extremes quietly fades, before price itself actually turns.
