Peak returns actual peak values, not just 1 (true) or 0 (false).
Therefore, when you multiply the result of Peak by shapeCircle (a scaler constant) you are getting a whole range of values, none of which are valid shape constants.
To correct your code, multiply the shape constant by an expression that results in either a 1 (show shape) or a 0 (hide shape).
e.g.
PlotShapes(shapeCircle * (High == PvtPeak), colorRed, 0, H, 20) ;
