Active Trader Pro
Active Trader Pro is a professional trading platform developed by Fidelity Investments, designed for active traders who need real-time market data, advanced charting tools, order management, and portfolio analysis. It is a desktop application used primarily by experienced investors and day traders who require responsive performance and sophisticated trading features. The app has historically only been available as a Windows-native or WINE-based emulation on macOS, making it a resource-intensive solution on non-Windows systems.
AI Recommendation
1 suggestionActive Trader Pro currently runs only under WINE emulation on macOS (combined with Rosetta 2 translation on Apple Silicon), delivering poor performance, frequent crashes, and memory overhead far exceeding what Windows users experience—reports indicate it consumes up to seven times more RAM on Apple Silicon compared to Windows. The current Intel-only release will stop working entirely when Apple removes Rosetta 2 in macOS 28 (September 2028). However, Fidelity announced in late 2024 that they are actively developing a native macOS build and have begun accepting beta testers. If you rely on Active Trader Pro, request to join the native macOS beta program directly from Fidelity—this is your most direct path to a supported solution before the September 2028 deadline. In the interim, if you cannot wait for the native build or prefer not to use beta software, consider switching to TD Ameritrade's Thinkorswim platform, which is already available as a native Apple Silicon application and offers comparable trading tools and market data, though you would need to transfer your charts and settings.
