DeMarker Oscillator
A technical analysis oscillator developed by Thomas DeMark used to determine overbought and oversold levels in the market. A reading above 0.7 signals overbought conditions, while a reading below 0.3 oversold conditions. The formula is calculated as follows: DeMax (n) = High (n) – High (n-1) provided the difference is positive, otherwise, DeMax = 0.
Also, DeMin (n) = DeMin (n) – DeMin (n-1) provided the difference is negative, otherwise DeMin = 0. Finally, DMark (n) = SMA (DeMax, n) / (SMA (DeMax, n) + SMA (DeMin, N)).
