Professionals, please advise. If I have a pending stop order placed, but the price has entered it with an extended spread that exceeds the stoploss.... What will happen?

The order will be eaten by the spread... Or will an error occur and the order will not be triggered?

 

Colleagues, what is the most detailed advice?

I have a pending order X

How to close the order after N hours from the moment the pending order was created?

An additional condition: the pending order may become a market order.

In the case if the pending order remains pending, everything is simple.

The case when a pending order becomes a market one is interesting (i.e. the moment when the pending order becomes market order, the time of creating it also changes).

I would like to get ideas from professionals to solve this problem, and better yet, I would like to get a code for this situation

 
zorber:

I would also like to solve this problem, but the thing is that in the tester when a pending order is triggered.... order type does not change... and it doesn't show up in the log as a market order... and i couldn't tell if it was triggered or not from the log data(((

Worst case scenario for you and will happen
 

Good afternoon. PEOPLE, ANSWER THE QUESTION PLEASE (3rd time posting). Question about a file index... In my MQL4 book, found at MQL4.community, in the "Standard Functions" section, there is an example of the script "File Operations", which is intended for reading data from a file and displaying graphical objects in a symbol window:

Below, when analyzing this script in the Book on MQL4, the following phrase is given: "if the specified check (the last 2 lines in block 5-6) is removed, an extra object will be created at runtime. And only after that, the while loop's termination condition will trigger and control will be passed to block 8-9".

Do I understand it correctly? A file pointer is NOT INFLOWED BY TEXT SIGNS (for example: text| where | is a file pointer), but is a pointer WITH EXPRESSION, for example: text where k is the "to" character, k-th is highlighted by a file pointer. This explains the need for strings (see p.164):

      if(FileIsEnding(Handle)==true)   // Файловый указатель в конце
         break;                        // Выход из чтения и рисования
      //--------------------------------------------------------- 6 --

Indeed. At the penultimate iteration, after creating the LAST object

2007.05.11 18:30;JPY

the file pointer is at the position of the last object, i.e:

2007.05.11 18:30;JPY IndustrialManufacture

(where o is the "o" character, k is the file index). Then when control is passed to the while statement header, FileIsEnding(handle) function will obviously return true, because the file pointer is NOT at the end of the file, but at the LAST character of that file. Then when the first two lines are executed, the file pointer will move to empty space and if there are no lines

      if(FileIsEnding(Handle)==true)   // Файловый указатель в конце
         break;                        // Выход из чтения и рисования
      //--------------------------------------------------------- 6 --

the script will create a graphic (i.e. a line) with an empty description and a time coordinate that corresponds to 0. This is what is meant in the phrase: "if the specified check (the last 2 lines in block 5-6) is removed, then an extra object will be created at runtime. "

Question: do I understand correctly:

a) the definition of a file pointer;

b) the meaning of the phrase "If the specified check (the last 2 lines in block 5-6) is deleted, then an extra object will be created at program execution.And only after that the while loop's end condition will be triggered and control will be passed to block 8-9".

P.S. In order not to litter the forum, thank you in advance for your answer

 
Please tell me, when and why does the Expert Advisor sometimes open trades without SL and/or TP, even though they are prescribed in the settings? It opens, but does not modify.

Because there is a "spacer" between the "settings" and the OrderSend() command from the program code.
