dxFeed Courts Indicator Sellers Days Before TradingView Closes Off-Platform Sales
Market data provider dxFeed has pitched its dxScript scripting engine to firms that sell paid trading indicators, days before TradingView restricts off-platform sales of such tools.
From Sunday, November 1, access to paid invite-only scripts on TradingView can be sold only through its Marketplace, with vendors who continue taking payments elsewhere risking script blocking. This policy shift has prompted dxFeed, a subsidiary of trading technology firm Devexperts, to offer its dxScript engine as an alternative for indicator sellers.
TradingView's Marketplace currently lists 52 paid spaces, priced from $4.99 to $199 per month, with the platform reporting that over 1,000 authors have applied for inclusion. The new policy represents a significant change for indicator developers who previously could sell their tools directly to users.
Scripting Inside a Firm's Own App
dxFeed describes dxScript as a component that brokers, fintech firms and indicator sellers can add to their existing products. This approach allows vendors to maintain their own branding and commercial models without needing to build a scripting language from scratch.
The engine, launched in July as a JavaScript-based language running on dxFeed market data, offers features including backtesting and signal alerts. While the name is newer, Devexperts introduced DXscript in 2021 for traders writing their own indicators and opened its DXcharts library to custom JavaScript indicators in March.
An AI agent built into dxScript can convert trading logic written in plain language into code, providing a different approach than TradingView's September integration of AI assistants like ChatGPT and Claude for market data, screeners and alerts.
Scripting should be one of those building blocks.
Platform Fee Comparisons
Indicator sellers who use platform marketplaces face varying commission structures. TradingView's Creator Program currently charges 0% platform fees with no end date, following an earlier version that specified the rate would apply at least until October 1, 2026.
Other platforms take larger shares: MetaQuotes takes 20% of sales in its MQL5 Market, while Spotware keeps 30% in the cTrader Store it opened to algo developers in December 2024. These rates range from 0% to 30% across the three main platforms, creating different incentives for indicator sellers.
