Since my tweets aren’t going through on twitter, I wanted to add a quick stock market prediction here:
April 4 will be a big day (various astro signatures at play plus new Moon). For day traders, key activity will be from about noon till 1:40pm, especially at 12:10pm and at 12:55pm EST–watch for bigger moves starting at those times (or possibly starting with buying at 12:10 and selling at 12:55; if sell-off occurs at 12:55pm, there may still be a rebound 10min later).
This may have to do with some news, possibly military-related or some other unexpected event (“accident”), or may be people will just be feeling on-the-edge and the mass anxiety will spill over into an urge to buy/sell stocks/currency.
p.s. On March 28, Sun will square Pluto, which often seems to coincide with outbreaks of violence. With this and Jupiter-Saturn opposition being pretty precise that day, I’d expect a down day for the market, with caution being the mood for the day.

Follow-up for 03.28.11:
As predicted, the market was largely down on March 28, 2011. Not only was it down, but also the volume was low: “About 5.9 billion shares traded on the New York Stock Exchange, NYSE Amex and Nasdaq — the lowest volume in 2011 … light volumes reflect investors’ uncertainty…” (see yahoo link). Apparently, many were playing it safe and not trading or taking out profits after the last week’s rally.
