What is DeMarker Indicator?

The DeMarker indicator identifies potential exhaustion points and demand zones. It compares the current bar's high/low to the previous bar to gauge buying/selling pressure.

How DeMarker is Calculated

formula 
DeMax = High(i) > High(i-1) ? High(i) - High(i-1) : 0
DeMin = Low(i) < Low(i-1) ? Low(i-1) - Low(i) : 0

DeMarker = SMA(DeMax, n) / (SMA(DeMax, n) + SMA(DeMin, n))

Default period: 14

How to Interpret DeMarker

Above 0.7 indicates potential overbought/exhaustion. Below 0.3 indicates potential oversold/demand zone. Range: 0 to 1.
