一种融合价格与成交量分布的新型金融图表。
A new financial chart that combines price action and volume distribution into a single visual representation.
传统K线图已经使用了数百年。
它能够有效表达：
- 开盘价（Open）
- 最高价（High）
- 最低价（Low）
- 收盘价（Close）
但存在一个天然缺陷：
对于同样的OHLC数据，市场在不同价格位置发生了多少成交，传统K线无法表达。
例如，两根完全相同的K线：
- Open = 100
- High = 110
- Low = 95
- Close = 108
可能对应完全不同的市场结构：
情况A：
大部分成交发生在103~104附近。
情况B：
大部分成交发生在96~98附近。
传统K线看起来完全一样，但对于交易者而言，这两种情况的市场含义可能截然不同。
Traditional candlestick charts have been used for centuries.
They efficiently represent:
- Open
- High
- Low
- Close
However, they have a fundamental limitation:
They do not reveal where trading activity actually occurred within the price range.
For example, two candles may share exactly the same:
- Open = 100
- High = 110
- Low = 95
- Close = 108
Yet represent completely different market structures.
Scenario A:
Most trading volume occurred around 103–104.
Scenario B:
Most trading volume occurred around 96–98.
A traditional candlestick displays both scenarios identically, even though their market structures are fundamentally different.
糖胡芦图（Tanghulu Chart）的核心思想是：
不要只记录价格到过哪里，还要记录市场在哪些价格真正发生了成交。
因此，每个价格层不仅包含价格信息，还包含对应的成交量信息。
图形中的视觉权重由成交量决定：
- 成交量越大，该价格层越突出；
- 成交量越小，该价格层越弱化。
最终形成一种同时表达：
- 时间
- 价格
- OHLC
- 成交量
- 成交量分布
的新型金融图表。
The core idea of the Tanghulu Chart is simple:
A chart should show not only where price traveled, but also where trading activity actually occurred.
Each price level therefore carries both:
- Price information
- Volume information
The visual weight of the chart is influenced by volume distribution across price levels:
- Higher volume regions become more visually significant;
- Lower volume regions become less prominent.
The result is a chart capable of expressing:
- Time
- Price
- OHLC
- Volume
- Volume distribution
within a single visual object.
名称来源于中国传统小吃：
糖葫芦。
在很多市场中，成交量会集中在某个价格区域附近，形成中间较宽、上下较窄的轮廓。
视觉上类似：
- 糖葫芦
- 沙漏
- 山峰
- 火山
糖葫芦大多数情况下是红色的，而红色在中国股市中代表上涨，希望这个颜色带来美好的寓意。
“胡”字取自作者姓氏，因此命名为：
糖胡芦图（Tanghulu Chart）
The name originates from the traditional Chinese snack Tanghulu.
In many markets, trading activity clusters around certain price regions, producing shapes that resemble:
- Candied hawthorn sticks
- Hourglasses
- Mountains
- Volcanoes
Tanghulu are mostly red. In China's stock market, red represents an upward trend, and I hope this color brings auspicious implications.
The Chinese character “Hu” (胡) also references the creator's surname.
Therefore the chart is named:
Tanghulu Chart
- 表达价格
- 表达涨跌
- 无法表达价格内部成交结构
- Shows price movement
- Shows bullish/bearish direction
- Does not reveal internal volume structure
- 表达价格
- 表达涨跌
- 表达成交量
- 表达价格成交量分布
- 表达POC
- 表达Value Area
- Shows price movement
- Shows bullish/bearish direction
- Shows volume
- Shows volume distribution
- Shows POC
- Shows Value Area
单根图形承载更多市场信息。
Each chart element contains significantly more market information.
成交量最大的价格。
通常代表市场最主要的成交成本区域。
The price level with the highest traded volume.
Often interpreted as the market's dominant transaction price.
价值区域。
通常定义为累计约70%成交量所在价格区间。
用于观察市场主要交易活动集中在哪些价格。
The primary trading region.
Typically defined as the price range containing approximately 70% of total volume.
It helps identify where most trading activity is concentrated.
本项目并不是为了替代所有金融图表。
而是探索一种新的可视化方式：
让价格与成交量分布能够在同一个图形中被同时观察。
目前仍处于实验阶段。
欢迎提出改进建议，或者在你的工具采用这个设计理念。
This project is not intended to replace all existing financial charts.
Instead, it explores a new visualization language that integrates price and volume distribution into a single graphical object.
The project is currently experimental.
Feel free to share suggestions for improvement, or adopt this design concept in your tools.
