I have noticed that although I have DOM indicators enabled. I never see them on my DOM for the latest web release. I know the market is closed, but it’s been a while when I saw the DOM indicators last.
make sure chart and dom are linked (color dots- gray means off)
I would assume that it only shows indicators of only 1 chart at a time.
it will show all charts that are linked. when they show on dom if you hover cursor on it the chart associated to it will show up
