Zeev - I think the 5-day RSI actually did reach the buying level early yesterday afternoon. I would guess that the PTB (da Boyz, or whatever) have learned to anticipate and start buying intraday instead of waiting for the EOD number. I've seen this happen several times in the last couple of months - where the RSI was in the 30's the previous EOD, then the NDX dropped enough during the day to put it below 30, and the heavy buying came in almost immediately.
After all, it's no secret that, during this bull market, buying when the RSI goes below 30 has been a sure thing.
Hard work often pays off over time,
but laziness always pays off right now.
