top 20 list only update at end of the month, so I will have to wait until end of May to compare the top20 list to end of April, but I doubt it we will see any change in top20 list.
here is another possibility where the big volume came from, it could be from day trader bought in during early trading period, and some may already sold out when it didn't move up, then when price drop to next level another set of punters bought in again, then when it didn't move or drop a bit they sell..etc.
13.5c was the doji closing price, so before s/p hit 13c, total share traded was around 18m. so that means around 25m shares were traded from 10c-13c.
from the above that around 26.47% of total volume were traded at the doji level (13.5c+/-)
and 22.73% at 10-10.5c level, so almost half of Friday's volume were in this two price level.
if this is true that most volume are from day traders on Friday, and price closed near daily low, I suppose that most of them are already out by now?
