Hi Bill,
You may be interested to read Dan Norcini´s site. He is a hog and cattle trader and they were so upset by the wild movements during the night that they petitioned
The CME to stop night trading and guess what , no more Asian trading in cattle and hogs because they were ¨getting their heads blown off..
It’s all there in his own words.
Funny how when your own market is manipulated in thin trading hours you get upset but it could never happen anywhere else.
