I have some .ex4 indicators which I need to convert into .mq4 files to use them altogether. How can I do it manually?

If you don't have the original source code (.mq4), it would be illegal to decompile the .ex4 file.

I am not sure what is Illegal into it as they were shared Free. Also I don't have any intention to change them and claiming them as mine. I just want to combine them thus I can use them effectively.

What is provided freely is the right to use them on your charts .. not to use the code itself which is owned by its author .. unless he also shared the .mq4 source code.

I understand. But I have knocked the author where I got the indicators several times but no response. Also these indicators were created in 2008 probably.
Anyway, is there any way that I can use those .ex4 indicators directly in EA? I need to get an indication when all those indicators changes colors all together.

There's no need of the .mq4 to use them for an EA or an alerter.

To access the indicators you have the .ex4 files in an EA, use the iCustom function. If you haven't used iCustom, do a search and you will find lots of info.
You also need to know which buffer the values you are interested reside in. To see what the value is in each buffer, in MT4 open up the Data Window (Ctrl + D). When you hoover the mouse over a bar on the chart, the value for each buffer of each indicator can be seen in the Data Window.
In the iCustom function, you would then specify the buffer whose value you would like to return. Play around with it and you'll soon get the hang of how it works.

If you don't have the original .mq4 file, that means that the author isn't willing to share it .. so decompiling the .ex4 would be illegal.

Do you have the original source code ? If not, you have no right to decompile the crypted file. It's what I meant in my previous post.

I see this thread is old, just came on to see if any change was available to change an old ex4 file, lost mql4 file, now a bit stuck. i see Ferrufx' point.. but now in a bit of a conundrum

I explained this to you few hours back in your other thread.
By doing this, you are encouraging users to pirate codes which authors aren't willing to share.

There are a few coders on this forum who make design and code trading tools to sell and I have seen many examples of people who find nothing wrong in cracking the ex4 ( you only have to go onto eBay to see many examples of this ) and next thing you know that piece of software is for sell on some obscure website. No thought goes into the huge amount of skill experience and time that goes into programming the indicators/ea's/scripts etc it all comes down to making a quick dollar out of someone else's hard work and knowledge. I can think of several examples of free software coded on Forums ( that have been cracked and passwords removed etc ) that are currently for sale for thousands of dollars by unscrupulous Forex/Binary websites. This is the reason that many coders on Forums no longer post the source code mq4 so at least it makes it harder for those so inclined and thankfully the new MT4 appears at this stage to be very hard to crack.
So at best if it is not illegal then it is definitely immoral. So anyone who thinks its alright to decompile software needs to take a good long hard look at their moral compass.

Excellent post.
Alas, the more indicators and EAs that are shared on forums for free, the greater the impression becomes that the software is of little or no value -- and there is nothing immoral in pirating something that has no monetary value. I've been guilty in helping to propagate this notion by freely sharing indicators and EAs, and performing coding and troubleshooting on request. Like the other programmers here, my motive was to help other members, but in one sense I feel I've unwittingly betrayed my fellow developers by making it seem that if it costs nothing, then coding apparently requires little time, effort or expertise.
It's good to know that there are no decompilers available, at least not yet, for the new MT4. That will make the task of the thieves and lowlifes who look to profitably reverse engineer copyrighted material vastly more difficult.
I have left FF. Please don't expect replies to your posts.

Most of the people in this thread are talking about the ethics of decompiling code. From the legal perspective, this differs among countries. In US and Europe reverse-engineering a computer software is legal. https://en.wikipedia.org/wiki/Revers..ering#Legality
So in other words, if you bought the software (even without the source code), you can decompile it.

Whether that is true or not is not the most important part, which is that a lot of these dumb cunts never paid for anything in their lives and just want a free lunch after finding an ex4 somewhere online and hoping someone will reverse-engineer it for them. Secondly, those who did pay for someone to supply them ex4's intend to pass this off to someone else to change the original functionality in some way which I can't imagine falls under any legal grounds. There is no end to the spreading of the code once the box is opened, and that can't possibly be legal.
There's just no way you can skin this that doesn't result in the simple fact that people are shit and just want access to things they have no rights to.
The more mental gymnastics required to justify getting at source code that wasn't actually sold or given to you the more it should become obvious that it's wrong.

If it's hard to do it doesn't mean that it is not allowed. The fact that programmers do not want to show their source code doesn't make it illegal to decompile it and use the ideas (I assume there are 0 patented ex4 'inventions'). I can't see anything wrong with it. If I buy an ex4 and want to see the code in order to get the idea of how it's done and then eventually implement it myself (you can't just copy paste decompiled code into your app, wouldn't do much good. Another thing is you can't patent source code, that's why everyone is hiding it so much) I would have no issue in doing that. (Excuse my English).

Spule, I dont have a problem with your English, I understand everything you said. But you show a lack of understanding of basic concepts. Reverse engineering is not the same as decompiling. Decompiling can be done by anyone with a computer. Reverse engineering on the other hand takes skill, experience and a lot of effort. If you really want to see what a program does, ask the developer and he might give you a description for an extra charge. If he declines it is possible that he wants to protect something. That is his right, it took him lots of experience and effort to create something he considers valuable. It is not right for you to violate the restrictiins of the developer. That is a serious and in many cases a criminal offence.
Just to remind you of the seriousness, consider the trouble Uber is now in. They hired an engineer from Waymo to help develop a driverless vehicle.Waymo claims that the engineer used stolen code from his time employed there and reused the code at Uber. Now Uber is under a restraining order to stop development and the engineer is being investigated on criminal charges. There is a huge gap between driverless vehicle code and a piece of crap MT4 program but the principle is the same. Stealing is stealing.
EDIT:
Think about this. If Uber had merely reverse engineered a Waymo car (say from videos) plus used a little inside info from the engineer, its doubtful they would be in any touble and the engineer would not be facing any criminal charges. There is a very fine line between copying and stealing but its a line everyone must understand and respect.

CodeMeister, I appreciate your comment. Decompiling can be part of reverse engineering. As the basic concept is that you are trying to find out HOW THINGS WORK under the covers, isn't it? I am a developer myself. I have been a developer for 12 years now and this is how I understand it.
The example you gave here, I am not sure if we can even TRY to compare those two. First of all, when a company hires a developer (or a contractor) it usually states in the contract that all the work the person does BELONGS to the end client. Another thing is that I am sure that various patents were involved which changes things completely.
The view I have is that everyone can reverse engineer any software they got legally, look at the code, learn from it, borough ideas, but not REUSE it for commercial purposes.

Decompile is not same than reverse engineering. If you have 12 years coding you should know this. SAMBA in linux was RE. Decompile code is crack it and its illegal..If you need justification about this then I dont think this is the right place

Whats theb difference between taking a $2 candy bar from Walmart or hacking a bank for millions? Thsy are both stealing.
Most of will never be in a position like the Uber engineer. We will be tested in less obvious, but important ways like plagerizing in school or being offered stolen goods or decompiling code. How we handles ourselves in these situations says a lot about the individual, his family and his community.

This thread should just become a honey pot for any jack-off posting a request for cracking or offering services to crack/hack closed source software. The users posting such offers and/or requests should have their membership revoked.

Spule please go ahead and decompile Windows 10 or Nvidia's binary blob publish it on the web with your contact details and home address. Please let me know how long it takes for a legal team (or law enforcement agencies) to come and visit you.
.. First of all, when a company hires a developer (or a contractor) it usually states in the contract that all the work the person does BELONGS to the end client..
Any sensible company stipulates in their employment contracts that all work (drawing on a whiteboard, intellectual property generation etc etc) their employees do on company time (and sometimes outside of it) is the property of the company. The company then sells that work to it's clients (not just one client .. glad you aren't running my business).
The view I have is that everyone can reverse engineer any software they got legally, look at the code, learn from it, borough ideas, but not REUSE it for commercial purposes.
So you don't intend to make money from trading?
Do you give the code and intellectual property back once you've finished 'borrowing' them?
If the software is open source and/or released under a licensing agreement that permits you to re-use the code etc (e.g. LGPL, GPL, BSD etc.) then fine but you are talking about ignoring all license agreements and essentially thieving intellectual property. Don't get me wrong I'm all for open source but the cheap skates in retail FX don't even respect those licenses as my past experiences have taught me.
Anyway I digress. I was really just replying to tell that I'm 'borrowing' your house, car and the contents of your bank account. I just want to see how they work.

i have no need to have any indicator decompiled so from that point I am neutral in dispute between coders and indicator users.
like in every profession,in this case programming with MQL4, some programmers are more skilled than others and that might be reason why more skilled programmers wanted to hide their coding but casualty is end user of indicator..or skilled programmers have some personality issue..whatever.
maybe solution is to have legal obligation to programmers to provide source code but have right to charge fair price for it. if programmers refuse it then other side to have ability and right to decompile it.
NO MATTER THE SITUATION,NEVER LET YOUR EMOTIONS OVERPOWER YOUR INTELLIGENCE
