Above is a 1-minute chart of the S&P E-mini Futures Contract (@ES#, DTN IQFeed). The ADXVMA line is shown as a three color line overlaying the bars.

Formula

inputs: Price (NumericSeries), Length (NumericSimple);

vars: TR(0), DI_Diff(0), DI_Sum(0), ma(0), pdm(0), mdm(0), pdi(0), mdi(0), DI_Factor(0), VI(0), diff(0), HHV(0), LLV(0), WeightDM(Length), WeightDI(Length), WeightDX(Length), ChandeEMA(Length), out(0), j(0); once ma=Price; if(Price>Price[1]) then pdm=Price-Price[1] else mdm=Price[1]-Price;//This array is not displayed. pdm=((WeightDM-1)*pdm[1] + pdm)/WeightDM;//ema. mdm=((WeightDM-1)*mdm[1] + mdm)/WeightDM;//ema. TR=pdm+mdm; if (TR>0) then begin pdi=pdm/TR; mdi=mdm/TR; end else begin pdi=0; mdi=0; end; pdi=((WeightDI-1)*pdi[1] + pdi)/WeightDI;//ema. mdi=((WeightDI-1)*mdi[1] + mdi)/WeightDI;//ema. DI_Diff=pdi-mdi; if (DI_Diff<0) then DI_Diff= -DI_Diff;//Only positive momentum signals are used. DI_Sum=pdi+mdi; DI_Factor=0;//Zero case, DI_Diff will also be zero when DI_Sum i s zero. if (DI_Sum>0) then out=DI_Diff/DI_Sum else out=0; out=((WeightDX-1)*out[1] + out)/WeightDX; if (out>out[1]) then begin HHV=out; LLV=out[1]; end else begin HHV=out[1]; LLV=out; end; for j = 1 to Length-1 begin if(out[j+1]>HHV)then HHV=out[j+1]; if(out[j+1]<LLV) then LLV=out[j+1]; end; diff = HHV - LLV; VI=0; if (diff>0) then VI=(out-LLV)/diff; ma=((ChandeEMA-VI)*ma[1]+VI*Price)/ChandeEMA;//Chande VMA formula with ema built in. ADXVMA = ma;

math

Period - Period used in the ADXVMA calculation.
Flat Color - Color used to draw the flat areas of the ADXVMA line.
Trendling Color - Colors used for the uptrending and downtrending legs of the ADXVMA line.
