This is a interesting stock isn't it? it seems the price is mostly being held up by one buyer with a 260,000 order at 0.57,
move that and it will continue to drop albeit it on small volume initially.
My interpretation is that there are a lot of holders hoping to see another jump, but may become tired if a lack of buying continues.
I read another poster comment elsewhere about large volume needed to change direction, I believe this can only occur when the bottom is truely hit and it seems that 0.50 wasn't it. To get the momentum again to hit 0.870 you need to start much lower, and I don't know if the 0.47 is it, though I agree with the other posters that this is a more likely destination then back up in the short term.
