quickfix | The Go FIX Protocol Library rocket | Cryptography library

I am trying to create a schematron that checks if the metadata element with keywords exists and if it has been updated. I have the code to check if the metadata exists but I am unsure of what to add to check if the metadata has been updated.

This is the code I have so far:

How do I make intellij shut up about "Class can be a record" warning? The quickfixes it suggests are just making the class a record.

Say I just ran a linter in the terminal and I have a bunch of linter output in the standard format:

This particular broker does not provide a DataDictionary so I have to create my own based on their documentation.

This is how they send a particular message:

FIX.4.4|9=709|35=y|34=53|49=DUMMYBROKER|56=|52=20210211- 12:12:37.358847|55=AUD/CAD|55=AUD/CHF|55=AUD/JPY|55=AUD/NZD|55=AUD/USD|55= CAD/CHF|55=CAD/JPY|55=CHF/JPY|55=EUR/AUD|55=EUR/CAD|55=EUR/CHF| ... etc

• How can I allow QuickFix a field to appear multiple times?
• Once I recieve the message what is the best way to read it? I am using QuickFIX/n.

This would probably provide me the last symbol only:

In my VS Code extension, I have registered a command to remove a diagnostic:

I am using QuickFix/J 2.3.1 (same results with 2.3.0). I have a rather straightforward spring boot application, where a FIX service is one of the beans. It creates an initiator. Until recently everything worked fine. Suddenly I stumbled into the following issue - quickfix doesn't seem to even attempt to open a connection to the specified host:port. I do suspect that this can be something to do with my code, but so far I don't have a clue on how to figure out what is going on.

Here is the initialisation code (Kotlin):

I am using QuickFixJ with SpringBoot to publish market price data to Bloomberg. When publishing prices, everything is working well. However, I cannot see any prices published on Bloomberg when I hit ALLQ.

Event log files :

Problem: I cannot properly encode signature, according to https://docs.cloud.coinbase.com/exchange/docs/messages . No matter what I'm doing, I'm getting "Invalid signature" rejection.

I'm using QuickFix FIX engine, and my code is written in C++. Signature calculation code provided below. b64_encode and hmac_sha256 are based on OpenSSL functions and were verified in another parts of application, so they are expected to be working correctly (unless Coinbase actually expects another kind of encryption).

I have 2 Java integration tests, each of them creates QuickFIX/J FIX session with the same property file.

When second test is running once I try to start connector QuickFIX/J creates session and tries to register an MBean for it. In both tests sessions have the same name, so ObjectName for MBean is the same for second test and its registration fails.

What is a correct way for QuickFIX/J to unregister/clear MBeans that could be used in tests?
