Marshall Wall introduces the Dynamic Momentum Oscillator (Dynamo). Please refer to this article for interpretation. The Dynamo oscillator is a normalizing function which adjusts the values of a standard oscillator for trendiness by taking the difference between the value of the oscillator and a moving average of the oscillator and then subtracting that value from the oscillator midpoint.**********************************/var fpArray = new Array();var bInit = false;function preMain() { setStudyTitle("Dynamo"); setCursorLabelName("Dynamo", 0); setDefaultBarFgColor(Color.brown, 0); setStudyMax(101); setStudyMin(-1); var x = 0; fpArray[x] = new FunctionParameter("OscLen", FunctionParameter.NUMBER); with(fpArray[x++]) { setLowerLimit(1); setDefault(10); } fpArray[x] = new FunctionParameter("MALen", FunctionParameter.NUMBER); with(fpArray[x++]) { setLowerLimit(1); setDefault(20); } fpArray[x] = new FunctionParameter("LowBand", FunctionParameter.NUMBER); with(fpArray[x++]) { setLowerLimit(1); setDefault(23); } fpArray[x] = new FunctionParameter("HiBand", FunctionParameter.NUMBER); with(fpArray[x++]) { setLowerLimit(1); setDefault(77); }}var HighestSoFar = null;var LowestSoFar = null;var HighestSoFar_1 = null;var LowestSoFar_1 = null;var xOscAvg = null;var xMAVal = null;function main(OscLen, MALen, LowBand, HiBand){var nBarState = getBarState();var OscAvg = 0;var MAVal = 0; if (nBarState == BARSTATE_ALLBARS) { if (OscLen == null) OscLen = 10; if (MALen == null) MALen = 20; if (LowBand == null) LowBand = 23; if (HiBand == null) HiBand = 77; } if (bInit == false) { addBand(LowBand, PS_SOLID, 1, Color.blue, 1); addBand(HiBand, PS_SOLID, 1, Color.red, 2); xOscAvg = stochK(OscLen,OscLen,1); xMAVal = stochD(OscLen,OscLen,MALen); bInit = true; } OscAvg = xOscAvg.getValue(0); MAVal = xMAVal.getValue(0); if (OscAvg == null || MAVal == null) return; if (LowestSoFar == null || HighestSoFar == null) { LowestSoFar = OscAvg; HighestSoFar = OscAvg; LowestSoFar_1 = OscAvg; HighestSoFar_1 = OscAvg; return; } if (nBarState == BARSTATE_NEWBAR) { LowestSoFar_1 = LowestSoFar; HighestSoFar_1 = HighestSoFar; } if (OscAvg < LowestSoFar_1) LowestSoFar = OscAvg; else LowestSoFar = LowestSoFar_1; if (OscAvg > HighestSoFar_1) HighestSoFar = OscAvg; else HighestSoFar = HighestSoFar_1; var MidPnt = (LowestSoFar + HighestSoFar) / 2; var Res = MidPnt - (MAVal - OscAvg); return Res;} |
