dsh-etf-monitor: A DSH sidebar panel to monitor National Team ETFs

dsh-etf-monitor is a DSH client plugin maintained by lacrimosa-da. It recalculates the estimated volume ratio, support pulse, premium rate, and excess for 15 broad-market and sector ETFs every 60 seconds during trading hours to determine if active capital is intervening to support prices. The data layer directly fetches public market data from East Money and Tencent using pure Node.js, requiring zero third-party dependencies and no API key. This article introduces the four sections of the dashboard, the metrics for the four assessments, two installation methods (GitHub source and source directory), four HTTP routes, independent snapshot usage, limitations of the metrics, and methods for running tests. It also explains that the plugin runs with the permissions of the current DSH process and that the source code and MIT license should be reviewed before installation.
