Previous action

Use this action with change({ id: 'Previous', context }).

Context

• id?: Get | Update (Update is assumed if omitted)
• forceVisible?: true | false
• color?, dashStyle?, lineWidth?
• field?: PreviousOpen | PreviousHigh | PreviousLow | PreviousClose

Behavior

Configures the previous-value guide line.

• Get returns current previous-line state in the same shape as Update context.

• Update applies provided fields.

• You must also enable showPrevious on the target plot (typically via Plot action, Update sub-action).

• Default style values are #888, Solid, and 1.

• forceVisible: true keeps the line visible even outside the current price range.
