In my opinion, trailing stop is more useful then simple "stop", Ameritrade US provide this function, but Ameritrade Canada does not.

本文发表在 rolia.net 枫下论坛Q: What is a trailing stop order?
A: Trailing stops allow you to protect profits on long or short positions by entering a protective stop that adjusts automatically with changes in the market price of the stock, rising or lowering as the price of the stock does. You can set their trail amount (the "stop parameter") in either percentage or points.

A few key points on trailing stops:
Available on Quotes & Trades, Rapid Order Entry, and Ameritrade Direct* (auto routing only)
Trailing stops are only available during the regular trading session. Trailing stops are not available during Extended Hours Trading.
Trailing stops are market orders when activated, not stop limit. An example of trailing stops in action:
Let's assume that you purchase 200 shares of XYZ Corporation at $35 per share. By using the Ameritrade Trailing Stop feature, you specify a trailing sell -stop order for $0.50.
Now let's assume the price of XYZ shares goes up to $36. Your Trailing Stop order will rise as well, to $35.50.
If the price of XYZ shares hits $37 before starting to descend, the sell-trailing stop rises to $36.50. Once XYZ shares hit $36.50, the stop is activated and your position in XYZ is sold.
The bottom line: You've made a $200 profit on the Trailing Stop sale of 200 XYZ shares.更多精彩文章及讨论,请光临枫下论坛 rolia.net

  • 枫下家园 / 理财投资税务 / 初用STOP,好多不明白的地方....请指教,并问哪里可以找到STOP的技巧?
    ACDO:
    13.91 buy
    set 13.45 STOP Limit 结果13.45出
    13。50 再买入 set 13.16 STOP limit
    涨到 14.20 回调,改设 13.79 STOP limit
    结果瞬间回调到13.75 后一直涨到14。80....

    疑问:
    1. STOP limit 好象容易被震仓....
    2. 设了STOP limit 后,这么设profit take the 单呢?(margine 用完了)
    3. 如果设 STOP limit 7%, 那不是亏有份,涨的时候卖却没有份吗?但价格上涨时如何提高 STOP limit呢?

    烦请有经验的大虾介绍一下技巧或推荐什么文章...
    谢谢
    • 大千回复:“stop我一般设10%,7%太小了 价格上涨用trailing stop :) hope it helps”
      比如我选10%

      ACDO买入: 13.91(10:30) ... STOP limit: 12.60 是全日的最低点...
      1. 那意味10% loss 如果看错。所有今天买的12M全套
      2. 那时有个13.50的小支撑
      3. 如果单日在13.30 - 14 波动,以后一直这样不是违背了day-trader 或 短线的原则了吗?
      4。什么是trailing stop? Ameritrade 没有这种服务,能介绍一下吗?

      我觉得stop limit 好在不会让人做股东;坏在没法出货或容易被3震出剧 ...

      谢谢!!!!
    • 呵呵,止损要是设得好,那是高手的一大特征啊。感觉1、你的止损价格设得太近了,容易被震出局;2、定好止损以后不要随便改。不太明白你为什么第二次买入以后为什么要那样改。
      你13.50买入的,13.16止损,后来涨了,然后你把止损改到13.79,这样子就高于你的买入价了,变成一个“止赚”了。
      止损的目的主要是最小化你的风险,这一笔你只能/愿意承受那么多损失,跌到一定价位,你感觉那个是个关键价位,跌破了还要跌,所以在那里stop loss。至于涨到什么时候卖掉,应该不归这个指令管了,要另外下“止赚”吧。(我不知道具体系统里面是怎么样子。)
      • 止(盈利的减少)也是一种止损的。
        • 哦,这样的。:P我懂得很少,你啥时候有空给全面介绍介绍?以前见过别人推荐一本大师的巨著,没看进去,惭愧得很。
          • 等小萨死了,我心情舒畅的时候,一定!
            • What if he is bombed to dust like Ladin so that nobody knows where he is?
              • 那就要让我很不爽了,还是不要吧
            • 谢谢先!:D 还是直接等你心情舒畅的时候比较可靠,万一小萨和小拉一样神出鬼没,我的求知计划就遥遥无期了。:P
              • 先把牛皮吹上。
            • 你做多啊。。看看美圆的走矢,死多有危险哦!!!

      • Good information. Thank you very much.
    • 我理解止损的含义
      主要是避免大的损失,而你的操作是day trader,stop当然要设置的小一点,2-3%是合适的,关键是你设置这么小的stop limit,如果发现操作方向反了,要能够马上反过来做(所谓的空翻多,多翻空),不然的话,你被震出局了,只能看着了。
      day trader一般要做自己熟悉的股票和指数股,一般来说是输的多赢得少。对于中长期投资来说stop limit 10%是适当的。
      =========================
      大钱存在于大势中。
      • 正是这样。我挑的是“突然”下跌的股值尚可/消息不致命的,但是“不熟悉”心理不塌实,所以2%-3%的stop容易引起心态完全失控...看来要想想如何把握...我个人觉得2000年是这种操作的黄金期,都是大牌有人气的股票跳水
        • 当你每次的投注太大时心态容易不稳,办法分散投资。短线操作就要身手灵活,凝重了就不好了。最忌不自觉的改变了初衷,回头一看很多矛盾,保持一种适合自己的投资风格。
          • 谢啊,早听到这句话我就不会把血本亏光了:((
            • 我也不是老手,以后多切磋交流!
        • 你是作daytrading?我一直觉得出入的时机不能根据价格上升或下降的大小决定。
    • happy_lamb的回复。谢谢大家的信息。等我再有实际超做了再根据新问题象大家请教!
      比如我选10%

      ACDO买入: 13.91(10:30) ... STOP limit: 12.60 是全日的最低点...
      1. 那意味10% loss 如果看错。所有今天买的12M全套
      我不是很建议当天买卖,你可以设一个10%的cut loss GMT order,10% 是买入价。设个时间,比如一个星期,这个order这个星期都有效
      我刚开始trade的时候,别人和我说12%的cut loss,经过试验,
      我觉得10%比较合适,振仓很少超过10%。

      2. 那时有个13.50的小支撑
      找支撑能赚钱,但比较危险。建议找支撑一定要在支撑附近买入,不然破了cut loss的10%,还没有到支撑,再跌过了支撑,损失会较大。

      3. 如果单日在13.30 - 14 波动,以后一直这样不是违背了day-trader 或 短线的原则了吗?
      建议:作短线,不要作day-trader,day-trader容易受心理因素影响。我的股票持有一般几天到两三个星期。

      4。什么是trailing stop? Ameritrade 没有这种服务,能介绍一下吗?
      trailing stop 是用来profit taking 的。比如你设个90%的stop,当股票上涨时,这个stop不会activate.比如你13元买入,
      股票涨到20最高点,下跌。这个order在20*90%=18会自动执行,
      你就可以profit taking
      • trailing stop should based on previous day's closing bid price not the highest bid price for the day.
        • I called. It is regular trailling stop. note: point means 1 dollor in Ameritrade. percentage is recommend.
        • Realy? I just wondering that in IB the trailing stop doesn't work, I think this maybe is the answer.
