It's basically a matched trade like SETS on the larger cap stuff. You quite often see them on the less liquid, as FRR is at the mo, SETSqx (named MMs and DMA auctions throughout the day, traded stocks)
It's designed to be price movement neutral trade. Right off to see if that bloke's finished with the wife yet ;-)
