I just sent this email out to a few exchanges... if ya agree with it, please get in touch with em too.
And of course, feel free to argy-bargy here
Howdy,
I write this primarily thinking of govvy and index rolls - but my arguments can be extended to calendar spreads in any FIFO markets!
FIFO is great is for the outrights, for sure. No worries there
The rolls, on the other hands, are more like STIRs, really. (both indexes and bonds). It's completely possible to upgrade your algorithms to be pro rata (or time priority pro rata or whatever) in the rolls while still FIFO in outrights - for example if there's 20 on the offer implied from the roll, and someone lifts it, then that is a 20 lot trade for the calendar spread handling algo.
No expert on commodities but one imagines similar applies.
This is win win for absolutely everyone. Locals like me will do the rolls more as we can compete. Rolls will have greater ranges and greater liquidity, benefiting paper. And there'll almost certainly be more volume, benefiting yourselves!
Finally, I sent this to LIFFE CME and Eurex (and I'll chuck in ICE even though they're irrelevant to me - but I did play on ECX for a bit and possibly still have an ITM - and everyone else loves the GSCI roll right?) so you won't even have to worry about patent infringement!
Not expecting this to be implemented tomorrow, but please do give it some thought
Kind Regards,
Dave
