A tiny little bit of theory.Skilled advisors, indicators and scripts for the Metatrader method are designed using the developed-in MQL language. Then, the resource textual content code MQ4 is compiled into executable binary code EX4. File with the EX4 extension includes program logic comprehensible to the Metatrader interpreter only. Los diez millonarios del mundo. We will not see something utilizing normal text editor. This is convenient in case if a programmer or trader give their program for use but doesn’t want the consumer to know the particulars of the revenue method.A problem.However, there are strategies of decompiling the EX4 files back to MQ4 which enable seeing the plan logic. This is a huge dilemma for those who want to maintain the details of their investing technique private.Decompiling can make it pointless to produce a business that is primarily based on sales of expert advisors or offering them for usage. The current businesses undergo excellent losses.Solution techniques.There is an impression that a very good MQL programmer can compose software in a way that would make it impossible to decompile. For illustration, by employing licensing program. Properly, sadly this is not the case. The approach are not able to be guarded by signifies of MQL only.

Enable us see several approaches of defending product sales techniques. We will examine them and uncover out their pros and disadvantages.1. Pure MQLAs we have already stated, this technique does not supply defense since an EX4 file can be very easily decompiled. However, alongside with the cons, MQL programming has its execs which will be examined in comparison with the other strategies.Professionals: basic structured language that is comprehensible by traders and not only by professionals. Cheapest value amount as in comparison to other approaches.Disadvantages: effortlessly decompiled.Specific characteristics: applicable for private use or for refinement of the strategies logic.two. DLLMQL language has a very beneficial special characteristic. It permits the plans to url with the libraries (DLL) composed in other programming languages. First of all, it in essence expands the opportunities and secondly, it allows moving MQL logic into the library which helps make decompiling of an EX4 file worthless.DLL can also be decompiled even so it is by no means easy and needs certain knowledge. When decompiled, the DLL code is translated into the Assembler (ASM) machine language. This treatment is named disassembly. Spend degree of ASM specialists is quite substantial, as a result this sort of bills are unreasonable for hacking most assignments.In addition, a task consists of two elements bare minimum: MQL+DLL, which can make the hacking work even far more difficult, since it needs teamwork of two specialists.Pros: very a large how to make ex4 to mq4 protection amount, unrestricted potential to expand opportunities of the MQL language.Negatives: larger advancement cost as in contrast to an MQL undertaking. Library installation needed.Special attributes: relevant for projects of regular value and reputation.3. On the web WEBThis technique implies shifting of the trade logic to Internet server. The user’s pc will have government interface only, with no the determination-creating module.MQL, DLL and Internet are employed in this architecture. MQL generates a ask for, DLL sends it to Net server, and the server generates and sends a reply that gets into MQL via DLL.

A file with the EX4 file extension is a MetaTrader Program file. It's compiled programming code made for the free foreign exchange market trading program called MetaTrader.

Stored in an EX4 file may be scripts or indicators used by the MetaTrader program. It may instead be an Expert Advisor (EA) program used by MetaTrader for automating trading.

The programming code in the EX4 file is compiled from an MQ4 file, which is a MetaTrader Custom Indicator file. This is done through a tool called MetaEditor that comes installed with MetaTrader.

EX4 files are used with MetaTrader 4, so EX5 files are very similar but are used by MetaTrader 5. MQH is another MetaTrader file format, called a MetaTrader Include file — you might see MQH files saved with EX4 and EX5 files.

Ext4 is a file system that has nothing at all to do with EX4 files.

How to Open an EX4 File

EX4 files can be opened with the free MetaTrader program from MetaQuotes. It works on Windows, macOS, and Linux. However, you might not be able to just double-click or double-tap the file and have it open in MetaTrader.

You can open the EX4 file another way, by putting it in the right folder inside the MetaTrader program's installation directory. For example, if you're using MetaTrader 5, this folder is most likely 'C:Program FilesMetaTrader 5MQL5.'

Once you're in that folder, you'll see several other subfolders. You have to know what the EX4 file is, specifically, so you know where to put it. It can be an indicator, Expert Advisor (EA), or script — put the EX4 file in the 'Indicators' folder if it's an indicator, the 'Experts' folder if an EA, and the 'Scripts' folder for EX4 files that are scripts.

In MetaTrader, you can see these files in the 'Navigator' window. If you don't see that window, enable it in the View > Navigator menu.

The EX4 file extension, though it shares some of the same letters, isn't the same as a file that has the EXO, EXR, EX, or EXE file extension. Follow those links to learn more about those file formats.

If you find that an application on your PC does try to open the EX4 file but it's the wrong application or if you would rather have another installed program open EX4 files, it is fairly simple to make that change in Windows.

How to Convert an EX4 File

Since EX4 files are the compiled equivalent of MQ4 files, you'd need a decompiler to 'convert' the EX4 to MQ4. I'm not aware of any decompilers that can do this.

You might also be able to convert an EX4 to EX5 or AFL (AmiBroker Formula Language). If so, it's most likely done through the MetaTrader program itself, but I haven't verified this myself.
