· 2 min read

Welcome to Version 30.2.0.

This release introduces a more efficient way to handle extensive symbol lists, adds smarter data loading for the VWAP indicator, restores the dynamic Depth of Market, and includes other improvements and bug fixes. Let's dive into the highlights.

Product update cover

Key updates​

If your app supports an extensive number of available symbols, loading hundreds of tickers at once can create a sluggish user experience during search. Now, you can optimize this experience using paginated Symbol Search.

Usually, the Datafeed API relies on searchSymbols to return all results in a single payload. Now, you can implement the optional searchSymbolsPaginated method instead. This allows the library to request symbols in pages.

For example, you can return the first 50 matches instantly, and as the user scrolls down the list, the library will automatically trigger a request for the next batch. For implementation details, see Additional Datafeed API methods: searchSymbolsPaginated.

Smarter data loading for VWAP​

Few things disrupt a charting workflow like adding an indicator and seeing an error message due to insufficient history. Now, the VWAP indicator handles this automatically.

Instead of displaying a warning when there isn't enough data to calculate the target anchor for the latest bar, the indicator detects the gap and automatically requests the exact amount of historical data required. This ensures a seamless experience for your users without them needing to manually scroll back to load more bars.

Return of dynamic DOM​

The Depth of Market (DOM) widget now uses dynamic mode by default, restoring the pre-v28 behavior where the spread stays in focus automatically. You can still provide the static mode by enabling the static_dom featureset.

Conclusion​

This release also includes other fixes to make the library more stable and reliable, from accurate rounding in the Hull indicator to fixing context menu interactions on the floating toolbar. For the full list of updates, improvements, and fixes, see the Release notes.
