do i send include file to client if so how do i protect it
@@JemillNoge To use these techniques ONLY send the ex4 or ex5 file to your client. The contents of the include file will already be in the ex file after compiling. Then send the licence for an account locked product or if the client has paid for the work treat the ex file like a sample. When the client pays then remove all the licencing lines from the source file and send the source of the expert or indicator to the client. There is no need to ever send the include file.
@@OrchardForex bullshit… they decompile all mt5 market and cloud protection…
@@Ama_Teur Really, do you have an example of a recently decompiled application? Do you really know what you are talking about or are you just trying to get attention?

The best channel about MQL ... clearly You have outside mql experience ...nobody writes code like this (professional approach) in mql education channels on UA-cam ... Thank You :) .. Regards
Thank you very much
This is the best MQL programmer on UA-cam. How I wish I can learn how to code in a similar fashion.
IMPORTANT:.. In order for this to work you must make sure that when you write this EA code that you put the #define lines ABOVE the line where you #include the LicenseCheck.mqh. By the time that the compiler reads the #include line and compiles the .mqh it must have ALREADY read the #define lines FIRST in order for the #ifdef lines to work properly... Pip Pip...
You are one hell of a tutor too Jim. It's amazing to see you commenting here. I am the one guy who still likes your videos from as a way back as 2013. Keep up the good work old timers! I like you both.
..said one legend to another ? :D
These are great videos! I can't thank you enough for making them!
Glad you like them!
You are a genius sir. I watched some important lessons so far and think also i know your own unbeated EA strategy now. And by including my own to it as well after learning also your structures framworks i am gonna also improve it to the nextlevel :) so an unbelievable endless big thank you Mister Australia. Your work amazes me a lot.
Wow, thanks
Hello, where can I locate an email, link or site of the unbeaten EA strategy? Thx
Wow, what an interesting video. This has been my concern for a while, but you have just solved it for me. Thanks a lot. 👍👍
Thank you for your simple explanation to implement a license key!
You're welcome! Remember to check the pinned comment, there was an error in the video.
yay been wanting this can show us how to add a logo to our ea/indicator when somone drags it over
Excellent explanation! Thank you! I do have a question though... is there anyway (for a EA developer/provider) to write an EA section of code that can track, "see", or report if the account it is licensed to run on is being copy traded by either another copy trader EA or virtual platform? Essentially is there a way to stop or track the resulting trades from being copy-traded on the customers end to another account?
Thank you for the wonderful explanation 🥰 I would just like to get a code to protect the expert advisor and that it be specified with a year of use and be linked to the account number
Just add a check on the account number, or check the other videos in the playlist for different approaches. ua-cam.com/play/PL0iqkWGt8zznxMIWGGPVXD999Q9yzKrjd.html

Amazing! Thanks a lot! 🤩🤩🤩
hello, nice video!!. I have a question, I did exactly as you did but on the third file Licence Generator, the error defined KeyGen appear. I try to use chatgpt but he can not resolve the problem
Hello, I have followed all steps and no errors. But when i place the license key, It says invalid even when i am inputting it correctly.
Any chance you could do a video using an SQL database from wordpress hosting with your licensing concept? Would this work?
For example, client base on website SQL database which can be toggled Active or Inactive for each client. A person doesn't pay, change the database to inactive.
Amazing instructor/instructions! Curious if you have this no-loss EA for sale on MT4/5 Market?
If this file is an include, will it still be read when uncompiled? I experienced something unpleasant about my product being duplicated, but I put this restriction, will this inclusion still be read when uncompiled, I hope not
Hi. First of all, thank you for this very useful video and ideas.
I have a question related with the licence days functions... I have tried it using a VPS and the EA doesn't stop running on the date that it is supposed to end. If I close the platform and open it again, it stops. But if I leave it always open, in a VPS, it continues running. Is there any way of actually stopping the EA from running when it is supposed to, even if the platform continues open?
Thank very much
Yes, I only placed the check in the OnInit function to prevent the EA from being started. If you also want a runnning EA to shut down then include a second call in the OnTick function like this
if (!LicenceCheck(InpLicence)) ExpertRemove();
I will try it. Thank you for your help.
Excellent!
Many thanks!
Great video. Well explained.
Why it doesn't work for me? copied everything you made but if i try to put it on a pair in the demo account i have on my broker firstly it doesn't stop it even if i said to use it on a real account, secondly i only have the message for input the private key but not the actual box where to put it and it doesn't show me the private key on the expert folder on the terminal, do you know why? can it be that the code is old and maybe there were few new changes?
thanks in advance for your help
This has been the most valuble video I have ever seen on YT. Thank you.
Is there a way to code restrict the number of devices one can use the vode on at a given time? Let's say one only wants users to be restricted to 2 devices.
Yes, I use something like this but it requires access to an activation server to track the number of instances in use.
@@OrchardForex thanks for taking the time to respond. I appreciate it. Is there anyway you can make a video on how to do this. Again, thanks for your content

Thanks a lot you are the best
nice video, just one doubt....how does it work when you distribute this? you distribute the .ex4 file right? but what happens then with the licence_check.mqh file? can people potentially hack it?
So don’t send the mqh file
oh...im totally confused now sorry....if one of the first lines of the EA tells #include ..how can you not send the mqh file and just the ex4?
@@pedrosanchezroca181 Because the mqh file is embedded in the ex4 file. If you are asking this question then I don't think you are at the stage where you should be distributing your apps to others.
Love your work. Tx
So glad!
Thanks for the excellent video explanation. I have a question, is there an error in the coding of the keygenerator, I can't get a working key at all. Other restrictions work without problems.
Not that I can see. The KeyGen function returns a key as a string. There is an earlier error where the private key was not used but the function would still return a working key, just not protected. There is a pinned comment at the top of the list with a fix and the code on the web page is correct.
I just needed to clarify a related point for beginners:
If you create a custom indicator or EA on MT4 just for your own personal use on a PC, this licensing code wouldn't be necessary in that case, would it? The only copy or theft danger is being hacked past the firewall of your OS? I'm assuming MT doesn't automatically upload your data even when the default copyright displays 'MetaTrader, Inc.' when going through the initial dialogue boxes upon creation? Thanks for your fascinating video.
This video, originally planned to be the only one, is part of a 3+part series. The aim here is where you build the EA for someone else, want to let them try it out but not just take the demo and not pay.
@@OrchardForex Thanks for your reply. I completely understand your actual intention behind the video. It just left me wondering how safe one's intellectual work may be when there is no actual distribution beyond personal use on one machine.
@@jamesburtnett8144 The EA is not sent to the broker. It is as secure as any other file on your computer.
thank you for your videos I learned well. please can you show us how to protect the robot from copying operations to another account... thank you in advance

Oh god you are good at it! I have a question for you… can you contact me it’s about a secret ea but I can’t find why the warning code is not correct… please
So i must give all this files to the customer ? how can i control the license that i gived to the costumer ? and if the costumer edit the code himself ?
Thanks for your responds
The use case for this is to let your customer (who paid you to do the work) try the expert, then pay you, then you give them the files after removing the security code.
Thanks! I was wondering how this could be done. ... GOD Bless!!!
You're welcome
Very useful and exactly what I've been looking for, thanks! How do I protect the .ex4 file from being decompiled and copied, though? Is there an easy way to do it?
The MQL market claims to add an extra layer of decompile protection and I've heard there are commercial products that can do the same but I don't have any first hand knowledge of them. I also haven't heard of a successful decompiler for recent code but I'm sure someone is working on one.
Very good content, can this protect a custom indicator?
Experts, Indicators, Scripts yes
Thanks you ❤
Nice Idea ;) Love it!! Is there any way, to give the expire Date with the licence Key?
Yes, see this video ua-cam.com/video/wee3s0JnGFY/v-deo.html
What about copy trading software that copy trades from one account to another? Is it possible to implement something that let's you recognize when somebody does this? Because if you use a copy trading software like this you can of course undermine the need of a license.
You can't stop copy trading, but you still need a licence for the original trading software
Thank you very much for the fabulous work you are doing. I have a concern about the protection of my robot using a license key. I followed the video and managed to implement this , but the resulting ex4 file works on any account when it is supposed to be unique. How to do please? Thanks in advance
You have made a mistake somewhere. That's all I can say from your description. Maybe step through in the debugger and make sure the licence routines are being called.
@@OrchardForex Thanks for your answer, I will check it all.

No. No DLL at all. In the video I just included the mqh file
Could you show us how to make an include function that returns a double value like for instance RSI value... than turn this include into a dll file. After that, how to call it from your expert?? Thanks
Writing a dll would be an advanced topic and I'm trying not to get too complex with these videos. Is there a reason why you need a dll?

This is the path to the LicenceCheck.mqh file. Use the path where you stored the file.

Thx 🙏🙏🙏
What about metatrader 5.. you only keep using metatrader 4 but it wont compile in 5
I use MT4 because it is more popular. The code for licence testing is the same for MT4 and MT5. The only thing I showed that is MT4 specific is the example EA but you would be adding the code into your own EA so that should not be relevant.

how do you manipulate expired indicator mt4 to work?
The idea for the expiry date is to use it where you are being paid for custom work.

When they pay you you just make a new version with the restriction removed.
Its very useful code, thanks sir, I used this code for my EA but every time, it prints message "Invalid License " and EA removed. I used my account no and my private key to generate license code. Can't find the mistake. please help me.
Add a print statement in the licence check code and print out the hashed value the licence is comparing to. My best guess is that when you are concatenating the strings to be hashed you have a difference in the code used to generate the key in the script and the code in the licence check.
@@OrchardForex OK Thanks sir, in print different key printed while taking EA in service than generated key by generator,. How it is?
@@jagdishvasave2504 If you followed the example then the script and the ea are both using a common include file, so the logic to create the code is the same in both. The difference then will be that one of the inputs is different.
In the KeyGen function the include file first concatenates the private key and account number, then uses SHA256 to hash the value. If the script and the ea are both calling the same function and getting a different result then one of those 2 values is different. Try adding the print statement in the keygen function, print out both the private key and the account. Make sure both the script and ea are using the same include file.
