It would be more interesting to see a lengthier sample. Secondly what i suspect, is that odd-lot data, much like the Ameritrade index, is a lagging indicator. IOW on days that the market rises, retail is a net seller, on declines they are net buyers. Over a longer book of data there may be some cool divergance analysis, but on the most part, odd lot activity is merely going to look like an upside down index chart, with little predictive value.
