Entity constants

Overview

The Darvas indicator runtime exposes several enum namespaces for entity options. You can use the string literals directly (e.g. "solid") or the named constants (e.g. linestyle.solid) - they are equivalent.

`linestyle.*` - Line and border styles

Constant	String value	Used by
`linestyle.solid`	`"solid"`	Line, Box border
`linestyle.dotted`	`"dotted"`	Line, Box border
`linestyle.dashed`	`"dashed"`	Line, Box border
`linestyle.arrow_right`	`"arrow.right"`	Line only
`linestyle.arrow_left`	`"arrow.left"`	Line only
`linestyle.arrow_both`	`"arrow.both"`	Line only

Line("trend", {
  x1: 0, y1: 100, x2: 20, y2: 110,
  style: linestyle.dashed,
  color: "#22c55eFF",
});

`shape.*` - Marker shapes

Constant	String value
`shape.circle`	`"circle"`
`shape.square`	`"square"`
`shape.triangle_up`	`"triangle_up"`
`shape.triangle_down`	`"triangle_down"`
`shape.diamond`	`"diamond"`
`shape.cross`	`"cross"`
`shape.x`	`"x"`
`shape.arrow_up`	`"arrow_up"`
`shape.arrow_down`	`"arrow_down"`

Marker("signal", {
  x: ctx.i(), y: ctx.low(),
  shape: shape.triangle_up,
  size: 10,
  color: "#22c55eFF",
});

`size.*` - Text size presets

Used for textSize in Box and for Label size (as a numeric value - size.* is string-only for Box).

Constant	String value
`size.xs`	`"xs"` - extra small
`size.sm`	`"sm"` - small
`size.md`	`"md"` - medium (default)
`size.lg`	`"lg"` - large
`size.xl`	`"xl"` - extra large
`size.auto`	`"auto"` - auto-fit

Box("zone", {
  x1: 0, y1: 100, x2: 10, y2: 110,
  text: "Demand",
  textSize: size.sm,
});

`extend.*` - Box extension directions

Constant	String value	Effect
`extend.none`	`"none"`	No extension (default)
`extend.left`	`"left"`	Extend left to chart edge
`extend.right`	`"right"`	Extend right to current bar
`extend.up`	`"up"`	Extend upward
`extend.down`	`"down"`	Extend downward
`extend.both_x`	`"both_x"`	Extend left and right
`extend.both_y`	`"both_y"`	Extend up and down

Box("supply", {
  x1: 5, y1: 105, x2: 10, y2: 110,
  extend: extend.right, // box grows forward in time
  color: "#ef444420",
});

`text.align.*` - Text alignment

Horizontal alignment

Constant	String value
`text.align.left`	`"left"`
`text.align.center`	`"center"`
`text.align.right`	`"right"`

Vertical alignment

Constant	String value
`text.align.top`	`"top"`
`text.align.center`	`"center"`
`text.align.bottom`	`"bottom"`

Box("zone", {
  x1: 0, y1: 100, x2: 10, y2: 110,
  text: "FVG",
  textHAlign: text.align.right,
  textVAlign: text.align.top,
});

`text.wrap.*` - Text wrapping

Constant	String value
`text.wrap.none`	`"none"`
`text.wrap.auto`	`"auto"`

Line

Uses linestyle.* for the style option.

Box

Uses extend., size., and text.align.*.

Marker

Uses shape.* for the shape option.
