close - PineScript Variable

`close`

Overview

close reports the last traded price of the active bar. While the bar is open, the value updates tick by tick; after the bar completes it becomes the final close.

Remarks

Access historical closes with the history operator: close[1], close[2], etc.
On some synthetic chart types (e.g., Renko or Heikin Ashi) the value is derived from transformed data rather than raw trade prices.
When working on security requests, close reflects the requested symbol/timeframe context, not the main chart.

Example

//@version=5
indicator("Close vs moving average", overlay=false)

length = input.int(50, "SMA length", minval=1)
sma = ta.sma(close, length)

plot(close, "Close", color=color.new(color.blue, 0))
plot(sma, "SMA", color=color.orange)

bgcolor(close > sma ? color.new(color.green, 88) : color.new(color.red, 88),
    title="Close above/below SMA")
