Well, thats is most likely the case .. same as there could be dummy/fake buy orders that could support the SP but also might get pulled off if the price goes down..
You calling those orders big sells, no offence but 100k shares at current price level is only around 25k.. 100k was a large order when it was trading at around 2-3 dollars, not these days .. I reckon around 25c is a bootom and will rebounce in a near future ..
