I tried it and it didn’t work. For example, the indicator I’m monitoring
now includes isphone{name="user",exname="13"},
isphone{name="user",exname="x14"}
isphone{name="user",exname="a15"}
At this time, the program returns a new indicator
isphone{name="user",exname="d2"}, I hope to find this newly added
indicator quickly in the chart, because I have a lot of indicators.
