Hello fellow ag players, I just noticed the change in agricultural matching algorithms on globex( dated July 3rd apparently ). I was having a bad time figuring out what was happening lately. Now, every ( if I remember correctly ) grain futures is working with the K algorithm : http://www.cmegroup.com/globex/files/PriceBanding.pdf But WTF is the K algo? a TOP/LMM/FIFO/PRO-RATA/FIFO algo ? I can figure out what a TOP/LMM/PRO-RATA/FIFO is but not with the additional FIFO in between...LOL. Is it just defining the priority between Market Makers? It's the only possibility I see. Does someone knows the firm( s ) market making grains? Thanks for the clarification and thanks CME for introducing Marker makers in those markets. Every "improvements" you made this year were great, like the 5 ladder order book, continue on this path bye
