The article says it's not enough to accurately timestamp orders at the various order entry portals. I didn't understand why that's not enough.
GPS can provide fairly accurate timestamps. There's a few other GLONASS systems as well for extra reliability.
- SOTGO 10mo agoIt's probably possible to use timestamps, but I suppose you would have to handle ties in more places, with sequence numbers you only break ties once. It appears that the FIX specifications allows up to microsecond precision, but given the volume of messages it's still likely a problem. It's also easier to work with integer sequence numbers than timestamps, but that's also a small consideration.

- thijson 10mo agoThanks for the correction. I just know the Russians and Chinese have their own systems.
