The Watermark Indicator adds a watermark to the chart
background. It can be used to identify the user, his or her
organization, or the ticker symbol of the primary instrument in the
chart. The watermark appears as semi transparent text overlaying the
chart background. The indicator has setups that include: the watermark
text to be displayed, the position of the watermark, the font and size
of the watermark text, and the opacity of the watermark. Opacity
settings of low, medium and high are available. Increasing opacity makes
the watermark appear darker.
On the Mac OS X platform, the opacity settings do not function due to
platform differences. Using the custom color option, Mac users can
specify various custom colors, shades of gray for example, to control
the shade of the watermark
