这是正确的做法吗?

谢谢你,这很复杂,我已经把它简化了,只有几行。

有意思的是,如果不是太麻烦的话,可以看看。
 
MakarFX:
有趣的是,如果

for(i=k; i>=0; i--) {

如果(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)){

如果(OrderSymbol()==Symbol()){

如果(OrderMagicNumber()== Magic) {

{ 如果(OrderType()>1)继续。

如果(OrderType()==OP_BUY || OrderType()==OP_SELL) total++;

}}}}

//---

// total=OrdersTotal()。

如果(total<1)

大家好,我想创建自己的函数库,因为我经常在我的机器人中使用相同的函数。我所做的一切都是正确的。我创建了这个库,把它放在Libraries文件夹中,然后用#import把它插入我的指标中。

#import "andylib.ex4".

bool KeyPr (long l, string k);

string TestFunc()。

##进口

库中指定的函数,并有说明。但库中的函数没有被调用。我试着把对话框放在指标的文件夹里,甚至直接放在连接到对话框的指标的同一个文件夹里,都没有结果。问题可能是什么?

你写的东西不可能成功。

首先,你计算 "total++",然后清零并设置 "OrdersTotal()",即所有订单

你是否记得在库中的函数名称后面写上导出?

更好的办法是,不要做一个库,而是做一个带有函数的.mqh文件,即使没有类,编译时也只取那些需要的函数,并从EA/指示器中调用。
