Change of color in point graph

I cannot change a color of points in point graph. UpdateColor is not changing the color. Bellow is a code snippet:

Plot( 0, "Squeeze", colorBlack, ChartPoint, StyleSymbolCircle|StyleBringToFront );
UpdateColor( Squeeze(20, 1.5, 2 ), colorRed ) ;
momentum = Mom(14) ;
Plot( momentum, "Momentum", colorGreen, ChartBar, StyleSymbolNone );
UpdateColor( momentum < 0, colorRed) ;

The second UpdateColor works OK, while the first one is not changing anything.

Please help ;

Probably > or < with the Squeeze function.
"UpdateColor" changes color on bars where the specified rule is true.

I changed to first two line to:
Plot( Squeeze(20, 1.5, 2 ), "Squeeze", colorBlack, ChartPoint, StyleSymbolCircle|StyleBringToFront );
UpdateColor( Squeeze(20, 1.5, 2 )>0, colorRed ) ;
No change in color. However, some of the points have value 1,

When I change the chart type as bellow
Plot( Squeeze(20, 1.5, 2 ), "Squeeze", colorBlack, ChartBar, StyleSymbolCircle|StyleBringToFront );
UpdateColor( Squeeze(20, 1.5, 2 )>0, colorRed ) ;
Colors are OK, Bars are red

Didn't notice you were using "ChartPoint". You should choose other chart style in order to change colors.

Does it mean, that chartPoint does not support color?
I would like to have colored circles and bars showing other information. That is why it is crucial to color dots. Any suggestion?

You can use something like this:

PlotSymbol(a, "", 1, 1, AboveHigh, colorTransparent, colorRed, PlotSymbolCircle);
UpdateColor(close > open, colorGreen);
