STIX oscillator is a short-term trading oscillator that was published in The Polymetric Report. It compares the amount of volume flowing into advancing and declining stocks. Calculation: STIX is based on a variation of the Advance/Decline Ratio: A/D Ratio = (Advancing Issues /(Advancing Issues + Declining Issues)) * 100 The STIX is a 21-period exponential moving average of the above A/D Ratio. In MetaStock this would be: STIX = Mov((Advancing Issues /(Advancing Issues + Declining Issues)) * 100,21,E) To construct the STIX in MetaStock for Windows you would need to perform the following steps: * In The DownLoader for Windows create a composite of the Advancing Issues + Declining Issues. * In MetaStock open the composite and the Advancing Issues * Tile the charts so they can both be viewed. * Drag the plot of the composite into the chart of the Advancing Issues. * Create the custom formula: Mov((C/P)*100,21,E) * Plot this formula on top of the composite plot in the Advancing Issues chart. (The composite's plot will turn a purplish color when the formula is going to be plotted on it) * You can then drag that new plot to a separate inner window if you prefer. For interpretation refer to The Polymetric Report.
