/*********************************************************Provided By : eSignal � July 2004 Special contributions from Alexis C. MontenegroVersion 1.0 7/20/2004Notes:This formula is designed to calculate stochastics based onthe user-defined source selected from the "Montage Source"parameter via Edit Studies. The default, Standard, uses thetraditional highest high, lowest low and close similar to thebuilt-in Stochastics study.!!!!!!!!!!! After selecting a new source for the Montage Sourceparameter, select "OK" and close the Edit Studies window. Then go back into Edit Studies to view the required parameters for the selected source, if they apply. !!!!!!!!!!!!!!!!!!!!!!!!!!!!Formula Parameters: Defaults:1. Montage Source Standard [Options] Open High Low Close HL/2 HLC/3 OHLC/4 Standard AccDistStudy.ACCDIST ADXDMStudy.PDI ADXDMStudy.NDI ADXDMStudy.ADX ATRStudy.ATR BollingerStudy.BASIS CCIStudy.CCI ChopStudy.CHOP DonchianStudy.BASIS DonchianStudy.LOWER DonchianStudy.UPPER EnvelopeStudy.BASIS EnvelopeStudy.LOWER EnvelopeStudy.UPPER MAStudy.SIMPLE MAStudy.EXPONENTIAL MAStudy.WEIGHTED MAStudy.VOLUMEWEIGHTED MACDStudy.FAST MACDStudy.SLOW MACDStudy.MACD MoneyFlowStudy.MONEYFLOW MOMStudy.MOM OBVStudy.OBV OscStudy.OSC PercentRStudy.PERCENTR ROCStudy.ROC RSIStudy.RSI StochStudy.FAST2.

Montage %K Color Color.blue10. Montage %D Color Color.red11. Montage %K Thickness 112. Montage %D Thickness 113-17The last five parameters are changed dynamically based on theBasic Study selected from the Montage Source parameter. Ifthe name of any of these parameters is "NA" then no input is required for that parameter.**********************************************************/var xMA = null;var vBasicStudy = null;var xMA1 = null;var xMA2 = null;var xMA3 = null;function preMain() { setStudyTitle("Stochastic Montage");
