subscription must refer to one known data source
T418
A subscription must be known when the script is compiled and cannot be chosen from a value computed while it runs. Use the data binding directly, or a constant key or index.
Failing example
script "conf"
data (
a = subscribe(data.ohlcv)
b = subscribe(data.ohlcv, timeframe: 5m)
)
plot out = plot.line(title: "out")
fn cls(s: OhlcvData) -> float { return s.close ?? 0.0 }
on a.update {
let flip = (a.close ?? 0.0) > 101.0
out.plot(cls(flip ? a : b))
}Corrected example
script "fixed"
data chart = subscribe(data.ohlcv)
on chart.update { let close = chart.close }
