如何在MQL4中的订单启动栏上方设置几个订单

Question

我想创建一个止损订单，它将被置于上一个订单的启动栏的上方，以防这是卖单或低于前一个订单的初始栏的低点。这是买单。

以下是用于说明问题的图片（该示例描述了卖出订单案例）：

知道怎么做吗？如果我使用固定的止损，下面的代码工作正常。如果我用基于高或低没有的变量替换止损，则触发订单。

这是我的代码：

主要问题

一旦分配（按每个市场事件报价到货）

double HH = High[1],
       LL = Low[ 1];

您对 OP_SELL 的指示应予以修复：

ticket = OrderSend( Symbol(),
                    OP_SELL, 
                    Lots,
                    Bid,
                    10,
                 // ----------------------v--------------------------------------
                 // Ask              + HH * 10 * Point,
                 // intention was High[1] + 10 [PT]s ( if Broker allows ), right?
                    NormalizeDouble(   HH + 10 * Point,
                                       Digits      // ALWAYS NORMALIZE FOR .XTO-s
                                       ),
                 // vvv----------------------------------------------------------
                 // Ask - TakeProfit * Point * 10, // SAFER TO BASE ON BreakEvenPT
                    NormalizeDouble(   Ask
                                     - TakeProfit * Point * 10,
                                       Digits      // ALWAYS NORMALIZE FOR .XTO-s
                                       ),
                    "Set by SimpleSystem"
                    );

以对称方式审核并修改 OP_BUY 案例。

对于Broker T＆amp; C碰撞（这些不需要反映在回测中）评论：

MarketInfo( _Symbol, MODE_STOPLEVEL )
MarketInfo( _Symbol, MODE_FREEZELEVEL )

或检查 MT4.Terminal aMouseRightClick 符号中的 MarketWatch - ＆gt; STOPLEVEL距离的属性。

次要问题

还要检查 OrderClose() 的代码 - 由于价格错误，这会失败：

// ---------------------------------------------vvvvv----------------------------
   bool  res2  = OrderClose( ticket, Lots, OrderClosePrice(), 10 ); # was db.POOL()-SELECT'd
