Devexperts has updated DXcharts, its financial charting library, to allow broker development teams to build their own technical indicators using JavaScript, a capability the London-based company says lifts the previous cap on the number of studies firms could deploy.

The feature, which Devexperts calls custom studies, lets client teams write indicators with any calculation logic tied to price data. Developers can run multiple output series, choose from several visualization types, and use a set of built-in functions covering standard technical analysis calculations such as moving averages, standard deviation, and true range.

Custom studies connect directly to the chart and refresh in real time as historical data loads, according to the company.

Brokers Had Been Capped at a Fixed Indicator Set

Before the update, brokers licensing DXcharts were limited to the platform's existing library of over 100 pre-built indicators. That constraint matters in a market where most retail CFD brokers run on a small number of shared platforms, where the charting layer is one of the few areas where differentiation is still possible.

Whether custom JavaScript indicators will prove a meaningful edge in practice depends largely on whether broker development teams have the capacity and inclination to build and maintain proprietary studies.

Devexperts has tried this before. In 2021, the company introduced DXscript, a proprietary scripting language aimed at end traders who wanted to write and share their own indicators. The March 2026 update shifts the focus from traders to the development teams at firms licensing the library, exposing the functionality at the API level and adding utility functions for common TA calculations.

TradingView Has Offered Similar Tools for Years

The space Devexperts is moving into is not unoccupied. TradingView's embeddable charting library has long supported custom indicators through its „custom_indicators_getter configuration,” and Pine Script, TradingView's proprietary scripting language - has been the dominant tool for trader-built studies for years.

Denis Krivolapov, Product Manager of DXcharts at Devexperts, said the update would give firms "more autonomy over their product offering, and help them to set themselves apart from competitors, without the need for extensive customization work."

UI Control Added Alongside Indicator Feature

The release also includes a separate change: firms can now hide or show specific menu items and settings in the DXcharts interface. Devexperts says this gives licensees more control over what traders see without requiring deep modifications to the underlying code.

It is the kind of incremental UI control that most established charting vendors already offer, though a broader roundup of broker platforms in 2026 noted that DXcharts is increasingly competing for the same broker clients as MetaTrader 5, cTrader, and Match-Trader.

Devexperts has been active on the product front in recent months. Last week, its DXtrade platform acquired theScreener, a research data provider, in a move aimed at reducing trader drop-off.

In January, DXtrade Mobile added BrokerIQ integration to extend CRM tools to mobile users, and the company linked up with Arizet to offer a fuller infrastructure stack for prop trading firms.

A year ago, DXcharts added the Devexa AI assistant to handle developer queries around customization and integration, a feature positioned as an onboarding tool for new licensees.

Krivolapov said further updates to DXcharts are planned, though he gave no specifics on timing or scope.
