Hello Hanno,
Thank you very much for your explanation. According to the specification for
Citi's FX e-Commerce, the offending messages ("PO", "PI") are called
"Application Ping" and used to measure round trip, end-to-end latency time
between Citi and its counterparties. "PO" is sent by Citi's servers and we are
expected to reply with "PI" immediately.
Regards,
Serge
