i understand giff. however this is down almost 400% for the day. the day before was almost as bad. i thinking it has to do with shear volume of buying and selling crushing the controls set up to achieve a 200% return. AGQ was up more than 200% for a long time yesterday but than calmed down to a more normal pricing pattern.
