        while(err_modify_sell==0){//if buy is in profit for 20 pips and trailing stop started on it i want my sell to modify for take profit for just 5 pips.
       OrderModify(sell_ticket,sell_open_price,slsell,tp_sell);

你的书是一栏但两英尺宽吗？不，因为那是无法阅读的。他们是6英寸，有时是两列，所以你可以很容易地阅读。你的代码也应该是这样。我不会去来回滚动试图阅读它。用格式化的代码 编辑帖子，你可能会得到额外的帮助。
 

哦，对不起，我只是添加评论 来解释，我把它删除。

我也做了一些修正，只得到一个错误'=='不同类型的比较@125,24

很明显，你不明白什么是字符串......请做一些阅读和学习，否则你是在浪费你的时间。


这怎么可能有意义？

while (err_mf_buy=="0" &&  err_mf_sell=="0"){

bool, err_mf_buy怎么可能等于一个字符串？

这怎么会有意义呢？

if ("mf_sell"+"sp"<="Sell_ans" && "Sell"=="open"){

字符串mf_sellsp永远不会等于Sell_ans，一个字符串怎么会比另一个字符串小？

 
我已经做了修正，正如你所说的，把0覆盖成""是没有意义的，但得到的是错误。

mohsin360:
现在meta editor询问预定义变量的情况

买入是否已申报？

 if(mf_buy-bp == buy_ans && Buy == "open")

Sell_trail是否已声明？

while(buy_trail==0 &&  Sell_trail==0){

Sell_ans 是否已声明？

if (mf_sell+sp<=Sell_ans && Sell=="open"){

是否声明了Sell？

sp是一个int ......这有什么意义呢？

sp = "(sp+5)";
 
是的，我做了这些区分大小写的修正，目前正在对 策略进行回测，非常感谢。

不要浪费你的时间 ......在所有这些随机的修正之后，代码不会做你所期望的事情。
