这个指标也称为价格通道(Price Channel)在20世界70年代早期被里恰尔德·东奇安(Richard Donchian) - 就是金融市场的技术分析方面知名的专家 - 发明的。价格通道属于趋势指标种类,它的外表与信号很像Bollinger Bands指标的。但是唐奇安的价格通道根据一定期间内的最高与最低价格被构建的。
DonchianChannel Upper = HH(n),在n个阶段之内的所有High值(Highest High)中最大的值,组
DonchianChannel Lower = LL(n), 在n个阶段之内的所有Low值(Lowest Low)中最小的值
DonchianChannel Middle = (DonchianChannel Upper + DonchianChannel Lower) / 2
价格通道(Price Channel)对趋势和反趋势交易制度可以作为技术基础。
根据这个指标构建的交易制度的典型规则意味着:
为了使通道突破信号搜索简单化必须使用带着+2维数的指标挪动。
这种工作作风又对日内又对商品与原材料和证券趋势市场上的中期和长期业务非常合适。
因为国际外汇市场基本上是平衡市和平仓市场,为了使用以价格通道为基础的突破策略必须采用交易的过滤器。这样在唐奇安通道的范围以外组织价格的信号要挑选的。
工作最好方法是把突破信号结合和用确定趋势力量的ADX指标和考虑价格波动的ATR指标淘汰这些信号。
以Price Channel为基础的从头寸退出方法帮在常常强大价格猛冲以后发生的修正返回运动时无损失关闭交易。这样情况发生如果通道范围突破以后价格离开它很大的距离和帮在反向运动情况下不失去资金一部分,这有助于最有利的交易关闭。
在mode = 1情况下指标根据在n阶段之内Highest High和Lowest Low被构建的
在mode = 2情况下指标根据在n阶段之内Close被构建
