Hi,
We are beginning to see a number of queries from clients, typically US, non-MiFID requesting specific uses of tag29 in relation to their CSA arrangements. It appears that the use of 3 (cross as principal) is inconsistent across the globe. We see two typical requests
Please don’t send any executions tagged with 29=5 as that is not supported on our fix spec can you please map it to 3.
OR
Please can you tag all of your riskless transactions as 5 as 3 is not trusted as the interpretation is inconsistent.
Tag 528 could be used to indicate the risk / riskless nature of the order however that doesn’t seem widespread across the industry.
Is there further guidance that we should be providing to the market on the us of tag29 specifically what is CSA eligible and what isn’t?
