I think a few nervous nellies today hit the switch. Perhaps got a bit scared re change in Saudi oil minister.
I can see some of the program trading things (eg enter into Google 'Aussie Bulls MRM') changed tune too. Make of them what you may...
Let's see how the oil price goes overnight but WTI this evening Aussie time trading up 2 percent so the oil minister call, at this time of the daily cycle anyway, might not have been the right one.
May not be all over yet... Can change back as quick as it happened.
