This study is best used in trending markets.

DMI Difference Parameters

Parameter	Description
Display	Opens sub-window to set parameters • Color = Line color. • Weight = Line thickness. • Display = Line style: line or histogram. • ShareScale = Determines whether sharing of the vertical scales between studies is accepted. Auto = System determine whether sharing is feasible. On = Scale is shared regardless of the functions and studies displayed. Off = Scale is not shared. ShareScale must be On if study is overlaid on a study with multiple outputs.
MarkIt	Opens Specify Conditions window.
Period	Number of bars in the lookback range.
OB/OS	Opens sub-window with overbought and oversold parameters: • Color = Select a color for the line. • Weight = Choose a thickness for the indicator. • Type = Choose fixed or dynamic. Fixed = uses Level as a fixed OB/OS value. Dynamic = uses Standard Deviation and Lookback for a dynamic OB/OS value:. OB: MA(@,Sim,lookback) + factor * STDDEV(@,lookback) OS: MA(@,Sim,lookback) - factor * STDDEV(@,lookback) where @ is the study • Std Dev = Multiplier used to calculate high and low. • Lookback = Number of bars to compare to the current bar. • Level = Percentage of average OB/OS used to calculate predictor Ob/OS levels. • Display = Click this check box to display the component. • Style = Choose a line style.
