dsh-trade-chart

对话内交易图表渲染：模型调用 trade_chart 工具，K线/折线/柱状/面积图直接渲染在对话流中，纯自绘 SVG 零外部依赖；主图 EMA/BOLL、副图 MACD/RSI/KDJ 可组合开启，另有热点轮动矩阵与连板晋级天梯，支持波段自动标注与自由画线，800 根自动聚合、5000 根拒绝。

Renders trading charts inline in the conversation: one trade_chart tool call draws candlestick/line/bar/area charts as hand-rolled zero-dependency SVG; EMA/BOLL overlays, combinable MACD/RSI/KDJ panes, sector-rotation heatmaps and limit-up ladders, pivot annotations and free-form drawing, with auto-aggregation at 800 bars and a 5000-bar guard.
