You may specify Charting library widget parameters when calling its constructor. Here is an example of a call.
new TradingView.widget({
symbol: 'A',
interval: 'D',
timezone: "America/New_York",
container_id: "tv_chart_container",
locale: "ru",
datafeed: new Datafeeds.UDFCompatibleDatafeed("https://demo_feed.tradingview.com")
});
Below is a complete list of supported parameters. Note that you can't change the parameters once the Charting Library is created. Use Widget methods if you wish to modify the parameters after the creation of the Charting Library.
The default symbol & time interval of your chart. The interval
value is described in the Section. Mandatory
Sets the default timeframe of the chart. Timeframe is a period of bars that will be loaded and shown on the screen. Valid timeframe is a number with a letter D for days and M for months.
id
is an attribute of a DOM element that you wish to include in the widget. Mandatory
JavaScript object that implements the (JS API) interface to supply the chart with data. Mandatory
Default timezone of the chart. The time on the timescale is displayed according to this timezone.
See the list of supported timezones for available values. Set it to exchange
to use the exchange timezone. Use the overrides section if you wish to override the default value.
Setting this property to true
will make the chart write detailed API logs into the browser console. Alternatively, you can use the charting_library_debug_mode
featureset to enable it.
A path to a static
folder.
The desired size of a widget. Please make sure that there is enough space for the widget to be displayed correctly.
Remark: If you want the chart to use all the available space use the fullscreen
parameter instead of setting it to '100%'.

Boolean value showing whether the chart should use all the available space in the window.
Default: false
Boolean value showing whether the chart should use all the available space in the container and resize when the container itself is resized.

An object with the following structure:
{

{
name: "<study name>",
grayed: true
},
< ... >
]
}
type
is the list type. Supported values are:black
(all listed items should be disabled),white
(only the listed items should be enabled).tools
is an array of objects. Each object could have the following properties:name
(Mandatory) is the name of a study. Use the same names as in the pop-ups of indicators.grayed
is a boolean showing whether this study should be visible but look as if it's disabled. If the study is grayed out and user clicks it, then theonGrayedObjectClicked
function is called.
Starting from version 1.1.
This property has the same structure as the studies_access
argument that is described above. Use the same names as you see in the UI.
Remark: There is a special case for font-based drawings. Use the "Font Icons" name for them. Those drawings cannot be enabled or disabled separately - the entire group will have to be either enabled or disabled.
JS object containing saved chart content. Use this parameter when creating the widget if you have a saved chart already. If you want to load the chart content when the chart is initialized then use load() method of the widget.

The object containing formatting options for numbers. The only possible option is decimal_sign
currently.
Example: numeric_formatting: { decimal_sign: "," }
It is an object that contains the following fields:
- timeFormatter
- dateFormatter
You can use these formatters to adjust the display format of the date and time values.
Both values are objects that include functions such as format
and formatLocal
:
function format(date)
function formatLocal(date)
These functions should return the text that specifies date or time. formatLocal
should convert date and time to local timezone.
Example:
customFormatters: {
timeFormatter: {
format: function(date) { var _format_str = '%h:%m'; return _format_str.replace('%h', date.getUTCHours(), 2). replace('%m', date.getUTCMinutes(), 2). replace('%s', date.getUTCSeconds(), 2); }
},
dateFormatter: {
format: function(date) { return date.getUTCFullYear() + '/' + date.getUTCMonth() + '/' + date.getUTCDate(); }
}
}
The object that contains new values for default widget properties.
You can override most of the Charting Library properties (which also may be edited by user through UI) using overrides
parameter of Widget constructor. overrides
is supposed to be an object. The keys of this object are the names of overridden properties. The values of these keys are the new values of the properties. Example:
overrides: {
"symbolWatermarkProperties.color": "rgba(0, 0, 0, 0)"
}
This code will make the watermark 100% opaque (invisible). All customizable properties are listed in separate article. You can use Drawings-Overrides starting from v 1.5.
The array containing names of features that should be enabled/disabled by default. Feature
means part of the functionality of the chart (part of the UI/UX). Supported features are listed here.

and resolution

property should have the following format: <integer><y|m|d>
( \d+(y|m|d) as Regex ). Resolution is a string and its format is described here - here. See this topic to learn more about timeframes.
The description
