dsh-trade-chart

Calling the trade_chart tool inside a DeepSeek Harness conversation renders candlestick, line, bar, or area charts directly in the chat pane as pure inline SVG. There are no external charting libraries to load and no copy-paste of static images; the moment the model replies, the chart is already interactive.

The capabilities span most day-to-day charting needs. The main pane accepts EMA at any custom period and BOLL bands with a filled zone. Sub-panes let you mix and match MACD (DIF, DEA, histogram), RSI with 30/70 overbought-oversold bands, and KDJ at the default 9-3-3 setting. A volume pane carries MAVOL alongside the volume bars, and the line, bar, and area chart types support multi-series comparison with a legend and hover tooltips. Two scenario-specific visualisations are built in as well: a sector-by-date rotation heatmap using the red-up / green-down A-share convention, and a board-by-date consecutive-limit ladder that auto-calculates promotion rates and lists individual tickers when the high board has few names. Enabling pivots marks local highs and lows with coloured triangles and price labels, while the annotations parameter supports horizontal lines, trend lines, arrows, rectangles, and free-text notes. Interaction covers wheel zoom with a locked Y axis, drag-to-pan, double-click reset, and a crosshair that adapts to whichever pane is under the cursor. Charts longer than 800 candles are auto-aggregated, and anything beyond 5,000 is rejected to keep rendering smooth.

The plugin is aimed at traders and analysts who work inside DSH chats and want to review daily, weekly, or monthly candlesticks, compare closing prices across multiple tickers, track sector rotation, or summarise consecutive-limit ladders. Describe the chart in a single sentence of natural language, and an interactive, zoomable, pannable SVG appears in the model reply.
