唐奇安通道（Donchian Channel）

 唐奇安通道（Donchian Channel）是一种经典的趋势追踪和突破指标。它由上轨（最高价）、下轨（最低价）和中轨（两者的平均值）组成，常用于海龟交易法。 

一、 核心构成

• 上轨： 过去 
  

  $$
   个周期内的最高价（买方力量体现）。
• 下轨： 过去 
  

  $$
   个周期内的最低价（卖方力量体现）。
• 中轨： （最高价 + 最低价）
  

  $$
   
  

  $$
   的平均值。 

二、 实战使用策略

1. 顺势突破交易（Breakout Trading）

• 买入信号（做多）： 当价格向上突破上轨时，表明上涨动能强劲，代表新趋势形成，可考虑买入。
• 卖出信号（做空）： 当价格向下跌破下轨时，表明下跌动能增强，可考虑卖出或做空。 

2. 震荡市中的反转与平仓

• 超买/超卖： 在横盘震荡的市场中，若价格触及上轨但未有效突破，可视为超买，常作为平仓点或反手做空的机会；触及下轨同理。 

3. 结合中轨确认趋势

• 持仓依据： 在上涨趋势中，只要价格维持在中轨上方，可保持多头仓位；反之若跌破中轨，则预示趋势可能反转。 

4. 波动率监测

• 通道宽度： 通道变宽代表市场波动性加剧；通道收窄代表市场进入盘整期（窄幅震荡）。 

三、 常用参数设置

• 短线操作： 常用参数为 20（如查看 20日 或 20小时 的最高/最低点）。
• 趋势跟踪（海龟法则）： 常用参数为 55，信号更稳健，能过滤掉部分杂音。 

[!TIP]
突破指标容易在震荡行情中出现“假突破”。建议搭配成交量（Volume）或相对强弱指标（RSI）等其他工具进行信号确认。

a 8-bar Donchian Channel | "every 8 days new low" indicator

 There is no single built-in "every 8 days new low" indicator on TradingView, but traders typically track this using a 8-bar Donchian Channel or a custom Pine Script that flags when the current price drops below the lowest low of the last 8 trading sessions. 

How to set up an 8-Day New Low

You can easily visualize an 8-period low on any chart (such as 1D for days, 1H for 8 hours, etc.) by using the built-in Donchian Channel:

1. Open a chart and click the Indicators button at the top.
2. Search for Donchian Channels and add it to your chart.
3. Open the indicator's Settings and change the Length to 8.
4. Uncheck the Upper and Basis lines so only the lower band remains. This line will dynamically update to show the absolute lowest point of the past 8 periods.
