T215
no overload matches these arguments
Severity Error
The built-in has several forms, and none of them accepts this combination of argument types and count. A common example is calling p.plot with three values: line-style plots take one value, candle and bar plots take four.
Compare the call with the signatures listed in the message and adjust the arguments.
Failing example
script "Heikin-style candles"
data chart = subscribe(data.ohlcv)
pane p = pane(title: "Smoothed candles", height: 0.35)
plot bars = plot.candle(title: "Smoothed", on: p)
on chart.close {
let o = ta.ema(chart.open, 3)
let c = ta.ema(chart.close, 3)
bars.plot(o, chart.high, c)
