The DeMarker (DM) compares the most recent price action to the previous period’s price in an attempt to measure the demand of the underlying asset. DM is generally used to identify price exhaustion and market tops/bottoms. The user may change only the period length. This indicator’s definition is further expressed in the condensed code given in the calculation below.


How To Trade Using DeMarker

Adjust the top and bottom guides to control the quantity and quality of the trading signals. If the DM crosses above the top guide a sell signal will be generated, Conversely, if the DM crosses below the bottom guide a buy signal will be given.
