Can you share a document or something that summarizes the abbreviations related to D2R ITAM trades that you often use here?

I’m afraid there are too many to list them.

You’ll need time and deduction, read through lots of posts.
Maybe take a day or 2 to come up with a list of terms you couldn’t understand and come back here to list it.
I’ll be glad to translate it for you.

Best I can do
