下面的代码看起来工作得不错，而且已经试过bool 'stoploss_use&takeprofit_use'，但有一次 没有正常工作，然后我怀疑这段代码，请让我了解一下。(如果有必要的话--我可以把所有测试EA的代码贴出来。）

void OnChartEvent(const int     id     ,
                  const long&   lparam ,
                  const double& dparam ,
                  const string& sparam
                  )
{
    // Sell
    if ( sparam == sellbutton )
    {
        ObjectSetInteger( 0, sparam, OBJPROP_STATE, false );
        // stoploss
        if ( stoploss_use == true )
        { sl = Bid + points_to_change( stoploss );}
        // takeprofit
        if ( takeprofit_use == true )
        { tp = Bid - points_to_change( takeprofit );}
        if ( !OrderSend( Symbol(), OP_SELL, lot, Bid, slippage, sl, tp, NULL, magic, 0, CLR_NONE ) )
            Print( " | OrderSend SELL: ", GetLastError() );
        return;
    }
    // Buy
    if ( sparam == buybutton )
    {
        ObjectSetInteger( 0, sparam, OBJPROP_STATE, false );
        // stoploss
        if ( stoploss_use == true )
        { sl = Ask - points_to_change( stoploss ); }
        // takeprofit
        if ( takeprofit_use == true )
        { tp = Ask + points_to_change( takeprofit ); }
        if ( !OrderSend( Symbol(), OP_BUY, lot, Ask, slippage, sl, tp, NULL, magic, 0, CLR_NONE ) )
            Print( " | OrderSend SELL: ", GetLastError() );

        return;
    }
}

所以，如果你说是的， 上述代码运行良好。那么我需要问的是，上述代码的组合是最佳的吗？ 所以，我只是想得到最佳的代码组合，也就是代码应该完美地工作。

请帮助我，或给我好的建议。
祝您一切顺利。

当它失败时，你会得到一个错误，你可以在文档中查找错误代码。

有时订单发送失败是因为滑点或偏离报价，所以它不一定是一个编码问题。

如果你把你的止损放在离市场价格太近的地方，这将是一个编码问题。

我也会为订单编写单独的函数，并在你的onchart事件中简单地调用这些函数。

但结果应该是一样的。

[Max Enrik]

Marco vd Heijden:

我也会写单独的函数来排序，并在你的onchart事件中简单地调用这些函数。

不错的评论，我已经开始把它们分开了，谢谢你。

[Max Enrik]

下面的代码组合好吗，请问？

// Sell
if ( sparam == sellbutton )
{
    ObjectSetInteger( 0, sparam, OBJPROP_STATE, false );
    ordersellfnc();
    return;
}

void ordersellfnc()
{    
    if ( stoploss_use   == true ) { sl = Bid + points_to_change( stoploss   ); }
    if ( takeprofit_use == true ) { tp = Bid - points_to_change( takeprofit ); }
    if ( !OrderSend( Symbol(), OP_SELL, lot, Ask, slippage, sl, tp, NULL, magic, 0, clrRed ) )
          Print( " | OrderSend SELL: ", GetLastError() );
    return;
}

预先感谢。

[Marco vd Heijden]

如果函数 失败，Ordersend会返回票号或-1。

[Max Enrik]

Marco vd Heijden:
如果函数 失败，Ordersend返回票号或-1。

哦，我不知道为什么我不能理解只是你的最新评论，那是问题吗？如果是的话，我该如何解决？

[Max Enrik]

#Checkmark - 打开

我可以使用下面的代码来设定 "默认止损 "值，这对我来说很有用。
但我已经花了几个小时来处理'Checkmark'使用'On/Off'，但不幸的是没有好结果。我有'位图标签'对象，当我单独 使用它时，效果很好，但当我试图这样使用它时。如果它是 "开"，"止损 "可以应用，如果 "关"，"止损 "就不能应用。

当我开始写这个函数的代码时，我以为我可以在短短几分钟内写完它。但不幸的是，它已经花了几个小时，请帮助我，那是在占用我的生命时间。

(如果你觉得我的担心很愚蠢，请不要责怪我，只是一个理由而已)

if ( stoploss == stoplossresetvalue )
{   ObjectSetInteger( 0, stoplossbmp, OBJPROP_STATE, false ); } else
{   ObjectSetInteger( 0, stoplossbmp, OBJPROP_STATE, true  ); }

    ObjectSetString ( 0, stoplossedit, OBJPROP_TEXT, IntegerToString( stoploss ) );

先谢谢你了。

[Marco vd Heijden]

位图标签的工作方式与按钮对象略有不同。

它使用两个位图，一个用于开启状态，另一个用于关闭状态。

因此，例如，您可以使用相同 bmp 的彩色版本和灰度版本来显示开启和关闭状态。

如果您确实使用了两张图片，请发布更多代码您在哪里设置状态？你想让它可以点击吗？目标是什么？

[Marco vd Heijden]

Max Enrik:
哦，我不知道为什么我不能理解你最近的评论，是这个问题吗？如果是的话，我该如何解决呢？

我只是想指出，OrderSend()函数 返回的是一个整数而不是一个布尔值。

如果函数失败，票号或-1与真或假是非常不同的。

[Max Enrik]

Marco vd Heijden: 

如果你确实使用了两张图片，请公布更多你的代码，你在哪里设置状态？你希望它能被点击吗？

首先感谢你的精彩评论，非常感谢。也许我没有描述我所关心的问题，但我将尝试再写一个。

所以，我总是试图在'test.mq4'中为我的想法写代码。我已经在其中使用了两张图片，其中一张是我想要的。我只是想带来以下功能。

1. 如果状态=真（图片显示为'开'）--我只想为这个功能写代码--'止损'可以适用于我的订单。
2. 如果状态=假（图片显示为'关'）--我只想为这个函数写代码--'止损'不能应用于我的订单。

我不能做这个功能，即使我在其他功能中已经使用了'Bitmap Label Object'，其他功能也能完美地实现我的要求。所以，请帮助我。

祝你一切顺利。

(我制作了.zip文件，所以你可以找到我的测试.mq4文件和2个.bmp文件格式 - 我希望这能帮助你理解我的担忧)
