Are you thinking about decompiling your EX4 to MQ4?

We have researched and tested several online ex4 to mq4 decompiler services, the only one we can recommend is Nordman Algorithms

They are previous metaquote developers who discovered a loophole in the MT4 system, they provide free ex4 to mq4 decompiler tutorials, free ex4 decompilers as well as paid services to decompile complex and new build EX4 to MQ4 on their website. They also offer custom MQL4 programming services.




Nordman is the real deal 👍. Alexei is just a wonderful human being to work with. He is highly responsive with the live chat, very patient, and understanding. Very thorough as well.

I had, what I would consider, a pretty complex NT8 indicator I wanted decompiled. I had already had a freelance dev on Upwork take a stab at it, and he could not implement it to my specifications. So I was actually concerned what I wanted could not be created within my budget range. Thankfully I kept searching and came across these guys. Alexei and his team got it done in under a month and the implementation was spot on.

I am very satisfied with my experience with Nordman Algorithms.

I have used Nordman Algorithms twice now and have found Alexei to be very helpful in achieving all objectives, communication/updates are timely and the standard of work is extremely high – I have no hesitation in recommending their services.

Alexei’s team is very responsive and very efficient. They were also very speedy with getting the EA done compared to other programmers I’ve worked with. Thanks Alexei!

In the last 10 years I have worked with several programmers. Nordman (Alexei) is really great, I told him I was not in a hurry but he developed the EA quickly and exactly as I wanted. Perfect and fast communication, correcting any point where I had not explained myself clearly enough.
For any other future work that I might need I will turn to Nordman Algorithms.
If you need quality work, especially if it’s complicated, I wholeheartedly recommend him.

We had a great experience working with Alexei at Nordman Algorithms. Indicator and bot were delivered within the agreed timeframe and within our budget (even over the Christmas period!). All queries and minor tweaks were responded to in a professional and timely manner. We would highly recommend Nordman Algorithms and will absolutely use their services again in the future.

I’ve been working with Alexei for every EA project I have created and I am very satisfied with the services from Nordman Algorithms. Alexei is very professional, patient and produces quality work in a quick turnaround time. I am glad I’ve found Nordman Algorithms and I would highly recommend them to anyone.

Alexei and Nordman were very prompt answering our initial questions and the level of service was incredible throughout the project.

I am happy to give Alexei my highest recommendation and I am not one to give recommendations normally.

Very impressive service and a great job that has exceeded all my expectations for the project.

For disclosure I have previously provided a review of this service, however as I have now used them to develop three seperate EA’s I feel as though it is fair for me to post again.

The last EA I had developed by Alexei and the team was a complex concept – certainly not a typical EA. Bill took the time to step by step work through all of the scenarios (including several I hadn’t anticipated) to make sure his understanding was right before creating the EA. And they nailed it.
This EA was as close to what I had envisioned as you can get – and the tiny things that we changed after that were to account for anomalies we identified with the broker not shortcomings in the EA itself (it was also around US election time so things were pretty crazy!). I’ll also add Alexei’s communication is the best I have experienced and with my time zone difference it worked beautifully.

The highest praise I can offer is that it was an out-there idea in my head, and within 5 days of starting the conversation it became a working EA in my account.

I have nothing but good things to say about Alexei and his team and recommend them to anyone.
