handler on snapshot source
T407
Snapshot-only sources cannot drive update handlers. Subscribe to an event-capable leaf or read the snapshot from another handler.
Failing example
script "conf"
setup fam = for tf in [tf("2m"), tf("5m")] {
subscribe(data.book)
}
plot out = plot.line(title: "out")
on fam.close(k, s) { out.plot(1.0) }Corrected example
script "fixed"
data chart = subscribe(data.ohlcv)
data book = subscribe(data.book)
on chart.update { let bid = book.bestBid() }
