[amibroker] IIF statement not making simple decsion based on REF statement.

["gmorlosky" <gmorlosky@xxxxxxxxx>]

I'm using the proven AmiBroker formula of SAR of RSI. Problem is that 
my "UpSAR" and "DownSAR" are always the same plot values, so I never 
see the other plot color. I'm trying to make a simple IIF statement 
based on REF of one day ago to plot green for upswing and red for 
downswing. Any help is appreciated.

//Title = "SAR Of RSI";

Plot( RSI(14), "RSI", colorBlue, styleThick );

P = ParamField("Price field",-1);

oldo = O; oldh = H; oldl = L; oldc = C; oldv = V;

O = H = L = C = p;
sar_flexible = SAR();

O = oldo; H = oldh; L = oldl; C = oldc; V = oldv;

/* split the plotting to green for upswing and red for downswing */

IIf( sar_flexible > Ref(sar_flexible,-1),
Plot( sar_flexible, "Up SAR", colorGreen ,styleDots | styleNoLine | 
styleThick ),
Plot( sar_flexible, "Down SAR", colorRed ,styleDots | styleNoLine | 
styleThick ));
