The colors do not come out at all. With the AFL coding below, the only result is Green Bars. I have limited knowledge of the AFL and definitely need help. The logic seems in place but my expertise with AFL is wanting. I would appreciate any assistance with the coding. R=(H-L);//RANGE; FR=(H-L)/3;//THIRD OF RANGE; S1=H-FR;//SEGMENT ONE; S2=H-2*FR;//SEGMENT TWO; S3=L;//SEGMENT THREE; /*POSITION OF OPEN AND CLOSE RELATIVE TO BAR*/ P=IIf(OPEN>S1,1,IIf(S1>OPEN<S2,2,IIf(S2>OPEN<L,3,0)));// POSITION OF OPENING PRICE ; CL=IIf(CLOSE>S1,1,IIf(S1>CLOSE<S2,2,IIf(S2>CLOSE<L,3,0)));// POSITION OF CLOSING PRICE; /*CONDITIONAL STATEMENTS */ COND_C=(((P=2 OR 3) AND CL=1)) OR (P=3 AND (C=1 OR 2)); //CLIMBERS COND_D=(P=1 AND (CL=2 OR 3) ) OR (P=2 AND (CL=2 OR 3));//DRIFTERS COND_N=(P=CL=1 OR 2 OR 3); // NEUTRAL BARS DYNAMIC_COLOR=IIf(COND_C,colorGreen,IIf(COND_D,col orRed,IIf (COND_N,colorBlue,colorWhite))); PlotOHLC( Open, High, Low, Close, "Price chart ",DYNAMIC_COLOR, styleBar ); Thank you, Pat Tobin
