dc1234 i agree there is persistent selling too.
i noticed this when exe was trading between 10c and 13 c, there was buying and alot of selling before it broke out. Now it looks like we r setting the same pattern, this time trying to break the .165c level. It might pan out like the time before and break higher above the resistence and then use it as a support or do the opposite and break down.
time will tell i guess.
