Donchian通道（唐奇安通道指标）是用于交易突破的最古老、最简单的技术指标之一。一般来说，唐奇安通道的宽度越宽，市场波动就越大，而唐奇安通道越窄，市场波动性也就越小。此外，价格走势可以穿过布林带，但你看不到唐奇安通道的这种特征，因为其波段正在测量特定时期的最高价和最低价。(Donchian channel is one of the oldest and simplest technical indicators for trading breakthrough. Generally speaking, the wider the channel, the greater the market volatility, and the narrower the channel, the smaller the market volatility. In addition, the price trend can pass through the brin belt, but you can't see this feature of the donchian channel, because its band is measuring the highest and lowest prices in a specific period.)
