Smart money are buying, I don't know how to interpret because usually such kind of buying happens when the market is sold off sharply indicating a bottom. But now the market wasn't down much. Well, the market had 3 consecutive down weeks (for QQQ it's 4 weeks), so it's bottomed?
How I use the chart:
I don't care what's the logic behind the chart. I found it works in the following two cases:
1.) When market up huge, if I see smart money huge short, best if new record short, then I know a short-term pullback is due soon.
2.) When market down, if I see smart money suddenly rises sharply from very negative value, then I know the pullback was over.
So I only use this chart for the above 2 cases. Besides those 2 cases, it means nothing to me. i.e. the absolute value of this chart means nothing to me, I only care if it rises sharply or drops sharply.
