###  | External Studies |

| External studies are contained in one or more libaray (dll) files. This allows for unlimited expansion to the studies included in SSChart. To add a study from this group, first select the Library which will make available all the studies contained in that library. Next select the Study. When you select a specific study other parameters specific to that study will appear in the Parameters group. If either the Price or Method groups are appicable they will be active, otherwise they will be grayed out. If you leave the * in the Name field, (recommended), the name will be generated automatically from the study name and the parameters. <click> [Apply] to add the study to the current chart.

Studylib1 contents: Ultimate Oscillator: This is the oscillator designed by Larry Williams that is a combination of three different oscillator periods. Chaikin Volitility Indicator Average True Range Note different average methods may be selected, none of them exactly match the method used by Welle's Wilder in designing this study. To match the method used Mr. WIlder, select the exponential method and a period = (Wilder's period * 2 -1) True Strength Index (Ergodic oscillator) True Strength Index Signal line Time Series Forcast (Moving linear regression): This is similar to a moving average but uses a linear regression to curve fit to the actual prices. Time Series Forcast Band: Similar to Bollinger Bands, but with standard deviation from a time series forcast rather than a moving average. Time Series Forcast Std. Dev: The standard deviation from the selected time series forcast. Trend Efficiency: Parameters are Period, Smoothing period, and Abs flag. Study gives the a percentage of the directional movement/total movement for the period. If Abs flag is set then the absolute value of the movement direction is used so range will be between 0 and 100%, otherwise range is between -100% and +100%. Keltner Channel: Parameters are period, offset, which price, and average method. (Variable average method not applicable). Creating this study will also create a moving average and an average true range study with the same period, you may hide these if you do not wish to see them, but they are necessary for the calculation of the Keltner Channels. The offset is the factor to multiply the ATR by before adding it to the moving average to get the channel value. To get both a high and low channel band, you will need to apply this study twice. Once with and offset of +1, and again with an offset of -1. (You can use any offset value, e.g. 1.5, -1.2, etc.) Parabolic SAR: Parameters used are Initial AF, AF increment, and AF Max. The default values are those specfied by Welles Wilder in designing this study. The study plots as dots, the line width parameter sets the dot size. +DI (Directional Indicator) -DI (Directional Indicator) ADX (Average Directional movement) These three indicators were published by Welles Wilder. Note his method of averaging the period corresponds to a period approximately twice the length for the normal exponential averaging method, so you may want to use shorter periods for these studies. (The 14 day period for this study is the equivalent of a 27 day moving average).
