are often quite weak as they engineer a reversal; sellers are gone, buyers sitting on the sidelines. The short term traders look for signs on a 15 minute or 30 minute intraday to confirm that the downtrend is broken for an entry signal. More often than not, the traders pick up a position closer to the end of the day to ensure that the day closes green.
My suspicion is that we might get a short green daily candle today, but lotsa volume and gains tomorrow. With NOT, though, who knows? If there's something coming down the pipe, all bets are off!
Just a little explanation of how the different players operate.
