plot anchor is not a top or bottom edge
T444
A stream marker or label plot can be anchored only to the pane's top or bottom edge. Use anchor.top or anchor.bottom, or remove anchor to place marks at their values.
Failing example
script "conf"
data chart = subscribe(data.ohlcv)
plot tag = plot.marker(title: "T", anchor: anchor.topLeft)
on chart.update { tag.plot(8.0) }Corrected example
script "fixed"
data chart = subscribe(data.ohlcv)
plot tag = plot.marker(title: "T", anchor: anchor.top)
on chart.update { tag.plot(8.0) }
