A New Exit Strategy - The ATR Ratchet By Chuck LeBeau 药渣译 一种新的止损策略——ATR棘轮法 The basic idea is quite simple. We first pick a logical starting point and then add daily units of ATR to the starting point to produce a trailing stop that moves consistently higher while also adapting to changes in volatility. The advantage of this strategy over the original Parabolic based exit is that when using the ATR Ratchet we have much more control of the starting point and the acceleration. We also found that the ATR based exit has a fast and appropriate reaction to changes in volatility that will enable us to lock in more profit than most conventional trailing exits. 基本思想是非常简单的，我们先选定一个合理的起始价格，然后每天加某一倍数的ATR，得到一个跟踪止损点。由该方法生成的止损点不仅能随着时间的增加不断上移而且同时也能适应市场波动性增减。与我们以前采用的由抛物转向指标得到的止损点相比，其优点在于：使用ATR棘轮，我们能更自由的选择起始价格和增减速度。此外我们还发现基于ATR的止损点能更快更准确的反映波动性变化，从而使我们能比传统的跟踪止损法锁定更多的利润。 Here is an example of the strategy: After the trade has reached a profit target of at least one ATR or more, we pick a recent low point (such as the lowest low of the last ten days). Then we add some small daily unit of ATR (0.05 ATR for example) to that low point for each day in the trade. If we have been in the trade for 15 days we would multiply 0.05 ATRs by 15 days and add the resulting 0.75 ATRs to the starting point. After 20 days in the trade we would now be adding 1.0 ATRs (.05 times 20) to the lowest low of the last ten days. The ATR Ratchet is very simple in its logic but you will quickly discover that there are lots of moving parts that perform a lot of interesting and useful functions; much more than we expected. 下面是一个应用该策略的例子：当我们1ATR以上的盈利目标实现时，我们选择一个近期低点（比如最近十天的最低价）作为起始价格，然后根据我们持仓天数每天将最低价增加零点几倍的ATR（比如0.05ATR）。如果我们已经持有仓位15天了，那么我们把0.05ATR乘以15天，然后将其乘积0.75ATR加到起始价位上。20天后，我们将把1.0ATR（0.05乘以20天）加到最近十天的最低价上。ATR棘轮法在逻辑上是很简单的，但是你马上就能发现有许多运动点能完成一些有趣且有用的功能，比我们想象的要多得多。 We particularly like this strategy because, unlike the Parabolic, the ATR Ratchet can easily be implemented any time we want during the trade.
