I like your use of high and low for yposition in bar/candle charts,
Nigel.
Re offset, the shapes surprisingly know UP from DOWN; changing 0 to -12
moves upArrows or Triangles DOWN and DownArrows or Triangles UP.
See code for Ken's example below. -Bob

Offset = Param("disp",-12,-50,0);
GraphXSpace = 6;
ActSig = MA(C,20);
Plot(C,"c",colorWhite,styleCandle);
Plot(ActSig,"ma20",colorBlue,5);
PlotShapes(IIf(Cross(C,ActSig),shapeHollowUpArrow,shapeNone),5,0,Low,Off
set);
PlotShapes(IIf(Cross(ActSig,C),shapeHollowDownArrow,shapeNone),5,0,High,
Offset);

Ken,
you seem to be leaving a few parameters out, see below

This plots a SmallUpTriangle in whatever color you have custom2 set to.

This does the same, but puts it on layer '-x'.
So (for example) to plot a hollowCircle on 'daily' layer (2), and
located
exactly on the BuyPrice.
PlotShapes(IIf(Buy, shapeHollowCircle, shapeNone), colorGreen, 2,
BuyPrice,0);
To move the shape up, change the 0 to a +ve number, to move it down,
a -ve
number. (Note that the symbols are all approx 11 pixels high).
So to plot a smallUpTriangle just above the high
PlotShapes(smallUpTriangle, colorGreen, 0, High, 12);
or just below the low
PlotShapes(smallUpTriangle, colorGreen, 0, Low, -12);
Hope this helps.
