Why you should use binary data in the exchange between server and client - Articles, Library comments

This article is about API and how to use it. Do you know an API that provides you with binary forex data? Then introduce it.

Next point, you criticise why use a normal computer to play FIFA2024 when a quantum computer is faster. The answer is simple, I don't need that kind of processing power.
So, the answer to this argument is that most of the data exchanged in this area in the API is in the range of a few megabytes, and there is no need for speed. In addition, all Forex data providers use standards such as XML, JSON...

I am not against the use of JSON. I use it myself, but only at the development stage, as you can always see a well readable response in PostMan or WireShark.

I was just pointing out that the article unfairly didn't even mention the binary format. Moreover, the more performant JSON binary (JSONB) is now gaining momentum.

If I have access to a server, I always use binary data in the exchange between server and client. There is only one reason why JSON is used everywhere: readable( for the user, but not for the computer). To have less dumb questions from users.

Even in websockets, where as a rule the transferred data is very small, I think it is reasonable to use binary data. At least because it is a more productive system with less load on the server and client side. And if you use cloud technologies, which is reasonable in today's highly competitive realities, you save a lot of money on their payment. After all, serialisation consumes a lot of resources and saves a lot of traffic.

Thank you very much for taking the time to share your thoughts with us. I completely understand your point, and the points you've raised about using binary formats and JSONB are very valid. You are right that JSON, in comparison to binary formats, is not as optimized for system performance, and this is something that many developers are aware of.

In the article we wrote, our primary focus was on JSON because 99% of financial data providers, particularly in the Forex domain, use this standard for data exchange, and many platforms and services provide data in this format. For this reason, we didn't cover other standards.

Once again, thank you for sharing your perspective and for pointing out this important detail.

Version for MQL5 METATRADER 5 I made changes to the code so that it would work in Metatrader 5. The changes were also made regarding the coding for better conditions in the current commercial situation. All the changes were to adapt the code to Metatrader 5. It is functional. And just download this file and run it. If necessary, the JAson.mqh library, which is found in the original code of our companion. My name is Ney Borges. I am from Brazil, state of Goiás, city of Caldas Novas, in the middle of the forest of Brazil. It was very difficult to learn alone without anyone to help, but here in the community I learned a lot. Thank you.

If necessary, you can use the JAson.mqh library, which can be found in the original code of our companion.

What a horrible way for google translator to work.

Without the JAson library, of course, it won't work.

The library is not in his code, it's here, and the author has specified that.
