Class: Series

A bar-aligned series of f64 values owned by the host. Read it Pine-style: s[0] is the current bar, s[1] one bar back; out-of-range reads are na.

Three flavours share this type:

  • the framework's OHLCV + derived series (src.*),
  • indicator outputs: every ta.* call returns a Series, so ta.ema(ta.rsi(src.close, 14), 9) and rsi[1] both just work,
  • user series from series(), written with s[0] = value each bar.
