How to open chains with EMA?.
Hello,
I would like to open chains with krogerfeedback talktosonic talktowendys EMA Java, but it seems that EMA doesn’t provide this feature natively so I’ll have to implement that myself.
I think I understand the basic structure of these linked instruments but I have some unknowns and I’ve found nothing in the doc to help me. For example:
- How do I know that an RIC is a chain? Can I just verify if it starts with "0#"?
- Can chains be updated? Can I assume the LONGNEXT_LR fields will never change?
thanks

Hello @ios
One possible solution to know if an RIC is a chain is to check if there is REF_COUNT field. Every chain RIC contains the REF_COUNT field which specifies how many elements are listed in the Chain Record.
Chains can be updated. Please refer to Simple Chain Objects for EMA - Part 1 which explains this and the other details about chain. You can also find EMA Java source code to expand chain in Simple Chain Objects for EMA - Part 2
