Hi. Is it possible that you are not seeing some expected arrowhead plots
because they are lost in the candle coloring?
IOW, is there still a problem if you try this:
// plot shapes with colors that are different from candle colors
PlotShapes( shapeSmallUpTriangle*nBuy_, colorBlue );
PlotShapes( shapeHollowSmallDownTriangle*nSell_, colorBlue );
PlotShapes( shapeSmallDownTriangle*nShort_, colorYellow );
PlotShapes( shapeHollowSmallUpTriangle*nCover_, colorYellow );
