或者你可以在检测到拖动时启动一个计数器，有很多方法可以做到这一点。
(我现在只有一种方法 可以做到--就是你最新评论中的方法）。
马可先生，你拯救了我，非常感谢。
暂时没有，但我以后会试着在这个 "SL 和TP"功能 上再增加几个功能。我只是在开始写脚本之前，真的需要研究很多这方面的东西。
祝你一切顺利!
如果我没记错的话--我在很久以前看到过一个 "订单修改器 "的EA是这样工作的：其中一个是在拖动时不更新的，当我 "拖动关闭 "拖线时，拖动后 "止损 和止盈"的数值可以改变一次。
所以我三番五次地阅读你的最新评论，也试着多改了一点，我可以在拖动时停止更新。
问：那么 ，请问这是不是不可能呢？
谢谢。
好吧，只要布尔标志拖==1，你就可以用这个相同的标志来禁止更新。
就像我说的，你也可以启动一个计数器，这是一个例子。

它只是说，当（我正在拖动）更新价格，直到它们变得相等（当我停止拖动）。
(和你的代码)
多么精彩的 例子啊!这真的是非常非常有用的评论，非常感谢。现在我正试图为那条线添加更多东西（设计和功能）。
(请不要责怪我的这个问题。我有 "graphics()"，我把它用于图形对象，我通过Init()调用它，我需要通过OnTimer()调用它，所以我的问题是：我做错了吗？)
祝你一切顺利!
你可能遇到错误4200，即创建对象 失败，因为它已经存在。
所以你必须在尝试（重新）创建或修改对象之前看看对象是否存在。
你可以使用。
{
//Object does not exist
}
and/or
if(ObjectFind(0,"Long")>=0)
{
// Object already exists
}
你可以使用。
嗯，这对我来说是个新功能。
我可以在研究后尝试一下。(我看到过很多次，但我从来没有用过它。)
非常感谢。
#将价格转换为像素 - 打开
我使用 "HLine "来实现止盈 功能。
我有几个对象（Label, RecLabel...等等），我想让这些对象能与 "HLine "对象一起移动。所以我找到了以下函数。但我不希望转换 "X"。我只想把价格转换为Y。
我从未尝试过下面的代码。
问： 因为我想确定它是否能帮助我解决这个问题？
(如果我知道它能帮助我，那么我将开始为我的问题而尝试)。
问： 是否有任何方法可以让一些对象用 "HLine "移动？
datetime time = 0; // I just want to ignore this because I just want to give to X = 20; fixed mode ( should not change ever )
double price = ObjectGetDouble( 0, "line", OBJPROP_PRICE, 0 );
int x,y;
ChartTimePriceToXY( long chart_id, int sub_window, datetime time, double price, int& x, int& y );
提前感谢。
你将不得不更具体一些，你可以用很多方法做很多事情。
这些函数在OnChartEvent()函数中使用。
ChartPriceToXY - 将给你的价格时间转换为坐标，这真的是你需要的吗？
也许你是指ChartXYToTimePrice()？

如果你不需要这个值，你可以直接把它作为一个零传递，见下面的例子。

我已经读过那份文件，但直到你的最新评论，我才清楚地意识到它。事实上，我还没有试过，因为我在下面的代码中挣扎，我已经尝试了一些方法来获得好的结果，但我做不到。
马可先生，谢谢你的最新评论，我觉得我可以用它来解决我的物体移动问题。
我真的花了很多时间来寻找解决我的问题的方法，我不能得到好的结果。
但无论如何，我可以得到（目前的开仓）获利 价格，也就是我想让 "hline "对象可以自己调用获利价格，并且它是有效的。而且它只是在最初的时候起作用。是的，我知道，因为它是在 "Init() "中。但我试着把它放在 "OnTimer() "中，但它没有正确工作。
请让我知道一些情况，以帮助我找出我可以学到的东西，并为我的这个问题做些什么。
我将在7小时后再次开始研究这个问题。
如果我得到好的评论，那对我来说会更好。

请使用样式器，它在工具标签下。
我不知道你想达到什么目的，所以我不得不猜测你想做什么，这绝不是好事。
但你可以看一下这里的例子。

所以你可以看到，你可以直接使用ObjectGetDouble，不需要把值复制到另一个double上，因为对象本身就持有这个值，当你拖动这一行时，这个值会自动改变，在你下次读它时就会看到。
