Problem with basic code

I am having problems with this most basic bit of coding. I am trying to compare conditions between various bars previous to the current bar. I tried the following and it plots price bars but not any of the Sells.

Plot( C, "Close", ParamColor("Color", colorBlack ), styleBar | ParamStyle("Style") | GetPriceStyle() );


Sell = (C-4 > C-1) AND (C-2 > C-4) AND (C-3 > C-2) AND (C-5 > C-3);

IIf( (Sell),PlotShapes(shapeDownArrow*Sell,colorRed),0);

Any ideas where I'm going wrong?

try this one

Sell = (C-4>C-1) AND (C-2>C-4) AND (C-3>C-2) AND (C-5>C-3);

_SECTION_BEGIN("db411");

SetChartOptions(0,chartShowArrows|chartShowDates);
_N(Title = StrFormat("{{NAME}} - {{INTERVAL}} {{DATE}} Open %g, Hi %g, Lo %g, Close %g (%.1f%%) {{VALUES}}", O, H, L, C, SelectedValue( ROC( C, 1 ) ) ));
Plot( C, "Close", ParamColor("Color", colorBlack ), styleNoTitle | ParamStyle("Style") | GetPriceStyle() );

PlotShapes( shapeDownArrow * Sell, colorRed,0,H,-12);

_SECTION_END();

db411

you can write as follows

Plot(C,"",colorBlack,styleCandle);
Sell = Ref(C,-4) > Ref(C,-1) AND Ref(C,-2) > Ref(C,-4) AND Ref(C,-3) > Ref(C,-2) AND Ref(C,-5) > Ref(C,-3);
PlotShapes(shapeDownArrow*Sell,colorRed,0,H,-12);

Your basic error is improper use of IIF(). Check the Users Guide for the proper syntax and also the section called "Common Coding Mistakes in AFL".
