This indicator looks to improve on Larry William's Accumulation Distribution formula The indicator subtracts a 10 period exponential moving average of the AccumDist function from a 3 period exponential moving average of the AccumDist function.**********************************/var fpArray = new Array();var bInit = false;function preMain() { setStudyTitle("Money Flow Indicator (Chaikin Oscillator)"); setCursorLabelName("Chaikin Oscillator"); var x = 0; fpArray[x] = new FunctionParameter("Fast", FunctionParameter.NUMBER); with(fpArray[x++]) { setLowerLimit(1); setDefault(3); } fpArray[x] = new FunctionParameter("Slow", FunctionParameter.NUMBER); with(fpArray[x++]) { setLowerLimit(1); setDefault(10); }}var xemaMax = null;var xemaMin = null;function main(Fast, Slow) {var nBarState = getBarState();var nMFI_Chaikin = 0; if (nBarState == BARSTATE_ALLBARS) { if (Fast == null) Fast = 3; if (Slow == null) Slow = 10; } if (bInit == false) { xemaMax = ema(Fast, accDist()); xemaMin = ema(Slow, accDist()); bInit = true; } nMFI_Chaikin = xemaMax.getValue(0) - xemaMin.getValue(0); if (nMFI_Chaikin == null) return; return nMFI_Chaikin;} |
