bid - PineScript Variable

`bid`

Overview

bid holds the highest price a buyer is currently willing to pay. The series only populates on tick charts ("1T"). On higher timeframes it remains na.

Remarks

Quote updates appear only when a new tick is processed; off-trade changes are not captured.
Always check not na(bid) when working outside tick charts to avoid propagating na.
Use alongside ask to measure spreads or monitor quote pressure.

Example

//@version=5
indicator("Bid tracking", overlay=false)

hasQuote = not na(bid)
plot(hasQuote ? bid : na, "Bid price", color=color.teal)

plotshape(hasQuote and ta.change(bid) > 0, style=shape.triangleup,
    color=color.new(color.green, 0), location=location.bottom,
    title="Bid uptick")
