OFF TOPIC.... My opinion: Until there is a *steady* increase in MFI ... regardless of the time of year ... we will not be out of the woods. Regarding ADI -- I think of this as "serious accumulation" rather than merely accumulation in general. Your point about institutional ownership (or lack thereof) is quite valid, but I still would rather have a trend of people buying 10,000 shares at a time rather than 500 shares at a time -- even if 10,000 shares equates to only $3,000 or so. In the case of TSIS, I reckon what it really does is screen out some of the "noise" of MM manipulation (though I don't see a lot of that any more since the AGM). I am still playing with the ADI indicator and refining it as time goes on. Rather arbitrarily, for each stock I study, I initially set the cutoff at a point which *includes* roughly 67% of all shares traded per day. To be rigorous, one should compute and plot multiple values each day, representing different transaction size cutoffs. When the charts diverge, then that is the correct cutoff size to use. I don't have the time to do this. I have not played with the "percent of total shares outstanding" concept, but might look at that some day. My initial thought is that the daily volume is such a small percentage of total shares outstanding that the numbers would be very, very small -- which can lead to *lesser* differentiation. The goal in all of this is to find a way of displaying the constant ebb and flow of supply and demand in a manner which immediately differentiates, but does not distort, the ebb and flow. One of the mechanical challenges I face is that my sole source for daily ticks wipes the slate clean about 9 PM exchange time, which is only 6 PM here on the left coast. If I miss one daily slate, the chart loses accuracy. If I could find a reasonably-priced source of daily ticks going back a few days, it would be real nice. Any ideas, anyone? JSb.
