Introduction

DeepSeek Harness (DSH) extends its capabilities through plugins. dsh-trading212 is designed to integrate Trading 212 portfolio data into DSH workflows. It is maintained by Kevoyuan and provides a configure-once experience for viewing positions and returns in both conversations and dashboards, eliminating the need for manual cross-app checking.

Core Features

  • API Configuration: Offers guided Demo or Live API setup with persistent credential storage.
  • Dashboard: Provides a responsive desktop and mobile interface with views for overview, positions, history, settings, and help.
  • Privacy Protection: Includes a “one-click privacy mask” (eye icon) that can hide all balances, position values, share counts, average entry prices, and returns.
  • Chart Integration: Uses TradingView Lightweight Charts to display price history from 1 day to 5 years, including minute-level short intervals and actual Trading 212 buy/sell execution markers.
  • Conversation Tools: Registers read-only trading212_portfolio and trading212_history tools that can be called directly in normal dsh conversations.
  • Multi-language Support: The UI supports English and Chinese, defaults to the dsh setting, and can be manually overridden on the settings page.
