Example scripts

Ten examples ship with the editor. Open one from Open ▾ → Examples, or from the Indicators list under My scripts. Each one is run by an automated test, so a change to the language cannot quietly break it.

Example	What it shows
EMA Cross	Two EMAs with buy and sell markers where they cross.
RSI with Bands	RSI in its own pane with overbought and oversold levels.
Bollinger Bands	Bands around a moving average, with the space between shaded.
MACD Histogram	MACD with a histogram that is brighter while momentum grows.
ATR Channel	A moving average with bands a multiple of ATR away.
Daily Open	A line at each day's opening price, restarting every day.
Higher-Timeframe EMA	An EMA from a higher timeframe, shown only once that timeframe's bar has closed.
Swing Pivots	Labels each swing high and low once enough bars have passed to confirm it.
Heikin Ashi Candles	Smoothed Heikin Ashi candles in their own pane, built with `plotcandle`.
Inside Bar	Highlights bars that trade entirely inside the previous bar.

Recipe: Bollinger Bands

//@version=5
indicator("Bollinger Bands", overlay = true)

len = input.int(20, "Length", minval = 1)
mult = input.float(2.0, "Multiplier", minval = 0.1, step = 0.1)

[basis, upper, lower] = ta.bb(close, len, mult)

plot(basis, "Basis", color.orange)
u = plot(upper, "Upper", color.blue)
l = plot(lower, "Lower", color.blue)
fill(u, l, color.new(color.blue, 90))

Recipe: a line at each day's open

//@version=5
indicator("Daily Open", overlay = true)

newDay = dayofmonth != dayofmonth[1]
var float dailyOpen = na
if newDay
    dailyOpen := open

plot(dailyOpen, "Daily open", color.yellow, 2, plot.style_linebr)

Recipe: an RSI pane with shaded zones

//@version=5
indicator("RSI with Bands")

len = input.int(14, "Length", minval = 1)
upper = input.int(70, "Overbought")
lower = input.int(30, "Oversold")

value = ta.rsi(close, len)

plot(value, "RSI", color.purple, 2)
hline(upper, "Overbought", color.red, hline.style_dashed)
hline(lower, "Oversold", color.green, hline.style_dashed)
bgcolor(value > upper ? color.new(color.red, 85) : value < lower ? color.new(color.green, 85) : na)
