Examples

Ten indicators from the Chartnaut public library, simplest first. Each page says what the indicator plots, which decisions in the script matter, and gives the full source.

#	Example	Shows
1	Volume	Histogram on its own price scale, per-bar colour, no state
2	Moving Average	`input.select`, a warmup that depends on a setting, the `foldBar` state pattern
3	Donchian Channels	Three lines from rolling highs and lows
4	ATR	True range with a choice of smoothing
5	RSI	Wilder smoothing and guide lines in a pane
6	Bollinger Bands	SMA with standard deviation bands
7	Stochastic	Stacked smoothing stages and a summed warmup
8	MACD	Two lines and a histogram in one pane
9	Supertrend	Path-dependent state and `warmup((w) => w.forever())`
10	VWAP	Session resets, `input.array` and `output.bandTemplate`

The examples are written against the current DSL: every script that keeps state declares its warmup, and every one survives the forming bar re-running on each tick. Some library rows still run older source, so Show source on a library indicator in Tools → Indicators can differ from these pages.
