unpredicatable pattern

An oxymoron? I just deleted it, but I had a great picture of the days FTSE trading from the 1st week of Jan 2008 and next to it one from the last 6 months of trading and you could not tell which was which. They were very similar. However while this looks like a fractal pattern we also know that the market cannot be predicted (efficiency of market). So it's a pattern which can't be predicted!
