OVERVIEW

This script is a tinny library for creating and displaying formatted values in TradingView scripts. It provides a structured way to present key information like titles, percentages, currency values, decimals, and integers with clear formatting. This allows you to coordinate your strings in advance and hold one item to use for calling your string to a label, box, table.. Made for day to day use of most typical use cases, more advanced techniques should be used for complicated scenarios.

Building Blocks

User Defined Types (UDTs)

The script defines a UDT called `DisplayValue` to encapsulate the components of a display value:

 * title: The title or label of the value.
 * format_string: The string used to format the value (e.g., "{0} -     1,number,percent}").
 * value: The actual value to be displayed.
 * format: An enum value specifying the desired format (percent, currency, etc.).

Enums

The `DisplayFormat` enum provides predefined constants for various formatting options, making the code more readable and less prone to errors.

Functions

 * create(): This function creates a new `DisplayValue` instance. It takes the title, value, and desired format as arguments and generates the appropriate format string.
 * to_string(): This function converts a `DisplayValue` instance into a formatted string ready for display on the chart.

1. Import the library:

### Notes

* The library handles the formatting details, making it easier to display values consistently in your scripts.
* The use of enums and UDTs improves code organization and readability.
