Thanks for trying to help Jerry! I am using 5.26 beta, and the data comes from IB pluggin, and I have been testing both ZU9 (sept2009 contract) and ZM9 (June) from LIFFE.
The thing is that they were both charting perfectly for weeks, then suddenly I had this change with prices being divided by 100 in the backfill. Not understandable so far !!! Carl
