Symbol Search

The Symbol Search is a button on the top toolbar that opens a dialog containing a search box. Symbol Search is used to search and display instruments that match the entered full or partial instrument name.

Symbol Search

Display symbols​

The way symbols appear in the Symbol Search depends on how you provide the data.

If you do not want users to change the displayed instrument, you can hide the Symbol Search. To do this, include the header_symbol_search featureset in the disabled_features array.

Set request delay​

If you want to reduce the number of search requests when users enter symbol names in the search box, you can set a request delay in milliseconds. To do this, use the symbol_search_request_delay property of the Widget Constructor. You can check out the Widget Constructor tutorial on YouTube for an implementation example.

Override symbol names​

Sometimes symbol names can be too long/short or implicitly reflect the meaning of the symbol name. In these cases, you can use the symbol_search_complete property of the Widget Constructor. This property overrides the entered symbol name with whatever human-friendly form you want. The overridden symbol name will then be requested by your server and plotted.

Filters​

When users click Symbol Search, the search dialog appears. The widget has predefined optional filters by symbol type and exchange. To use them, pass a DatafeedConfiguration object with the symbols_types and exchanges properties as a parameter to the callback of the onReady method.

Symbol grouping​

The search dialog can display symbols grouped by a root name. For example, to group futures ABC2023, ABC2024, and ABC2025 by the root name ABC, provide a regular expression to the library. The expression should consist of two capture groups, where the first is the root name and the second is the expiration date.

To enable grouping, provide an object with regular expressions to parse symbol names in the symbols_grouping property of the DatafeedConfiguration interface. Then pass the DatafeedConfiguration object as a parameter to the callback of the onReady method.

Display logos​

If you want to display logos for symbols and exchanges within the search results, follow the steps below:

  1. Enable the corresponding featuresets: show_symbol_logos and show_exchange_logos.
  2. Provide URLs for symbols and exchanges in the logo_urls and exchange_logo properties of the SearchSymbolResultItem object. Pass the object as a parameter to the callback of the searchSymbols method.

Enable spread operators​

Spread operators are operators that allow comparison between a financial instrument, such as a stock, and an additional variable, such as another financial instrument or a numerical value.

caution

The library does not handle the spread calculations, you should perform them on your server. For example, when users enter "APPL-TSLA", the datafeed is called with the AAPL-TSLA symbol name. The library expects your datafeed to resolve the symbol information and return the relevant data.

To display spread operators in the Symbol Search, include the show_spread_operators featureset in the enabled_features array.
