ShapePositionAbove must NOT be used together with shapes that have positions already included (all those which have "Down" or "Up" in the name). All "Down" shapes are positioned ABOVE already and "Up" shapes are positioned BELOW already, so it makes no sense to add those two.
So you may only use ShapePosition above to the following shapes: shapeSmallSquare, shapeHollowSmallSquare, shapeSquare, shapeHollowSquare, shapeSmallCircle, shapeHollowSmallCircle, shapeCircle, shapeHollowCircle, shapeStar, shapeHollowStar, shapeDigit0, shapeDigit1, shapeDigit2, shapeDigit3, shapeDigit4, shapeDigit5, shapeDigit6, shapeDigit7, shapeDigit8, shapeDigit9 See this link for more details http://www.amibroker.com/guide/afl/afl_view.php?id=206
