Yes I had the same problem a few weeks ago as has any trader honest enough to admit it... The affliction is called "Mad Cow". Typically is occurs only in the bovine species causing erratic behavior.. spastic motor control and the like... But from time to time it infests traders where it causes up to be down.. left to right... and so on... The only cure is the presense of mind and character to confront the disease and fight through it...
