DeepSeek Harness Trading Chart Plugin: Render Candlesticks and Indicators Directly in Conversations

`ikomom/dsh-trade-chart` is a client plugin for DeepSeek Harness. Its core function is to render financial charts directly in conversations using pure SVG. The plugin has no dependencies on external libraries and supports multiple chart types, including candlestick, line, bar, heatmap, and consecutive limit-up progression charts. It also includes technical indicator calculations such as EMA, MACD, and RSI, with support for automatic annotations and interactive operations. Users can install it via a local path, Git, or NPM. Note that rendering is rejected if K-line data contains more than 5,000 candles, and the plugin follows the A-share color convention of red for gains and green for losses.
