profile length must be known before the script runs
T423
Set bars using a literal, constant expression, or declared input default so the profile length is known before the script runs.
Failing example
script "conf"
data chart = subscribe(data.ohlcv)
data vol = subscribe(data.volume)
on chart.update {
let n = int(chart.close ?? 1.0)
let p = vol.profile(bars: n)
let t = p.total()
}Corrected example
script "fixed"
data chart = subscribe(data.ohlcv)
data vol = subscribe(data.volume)
on chart.update { let profile = vol.profile(bars: 10)
let total = profile.total() }
