Severity Error

The handler uses an event that the subscription’s source does not deliver. Bar-based sources (ohlcv, oi, funding, liquidations, vd, cvd, flow) have open, update and close; only data.trades has trade(tr), and that is its only event.

Use an event the source supports, or subscribe to the source that delivers the event you want.

Failing example

Flowscope Script
script "Big print marker"
data chart = subscribe(data.ohlcv)
plot big = plot.point(title: "Big print", color: color.poc)
on chart.trade(tr) {
  if tr.notional > 1_000_000.0 {
    big.plot(tr.price)
  }
}

Fixed example

Flowscope Script
script "Big print marker"
data tape = subscribe(data.trades, minNotional: 1_000_000.0)
plot big = plot.point(title: "Big print", color: color.poc)
on tape.trade(tr) {
  big.plot(tr.price)
}
