DT,
AFL does have tangent - it's TAN().

Anthony,For any point , D bars before the end of an
array y, we may draw an automatic line with ANGLEdeg [in degrees, positive
or negative.Avoid +-90, the tan is not defined there.Since we do not
have in AFL a tangent function [as we miss pi], we should use their
equivalentsD=50;ANGLEdeg=Param("a",45,-89,89,1);x=Cum(1);L1=LastValue(x);y=RSI();x0=x[L1-D];Y0=Y[L1-D];pi=4*atan(1);ANGLErad=pi*ANGLEdeg/180;z=y0+(sin(ANGLErad)/cos(ANGLErad))*(x-x0);Plot(y,"",1,1);Plot(IIf(x>=x0,z,-1e10),"",colorRed,1);Plot(IIf(x>=x0,y0,-1e10),"",colorRed,1);PlotShapes(shapeUpTriangle*(x==x0),colorYellow);Title="ANGLEdeg="+WriteVal(ANGLEdeg,1.0);Dimitris
