IOST has gaps in price discovery from about 780 to 700, and from about 609 to the current price.
IOST is currently a fairly high volume coin, it has several contacts on the support at 780, with sizable bounces off of it, before bleeding out and breaking below this support.
it is a slower drop, so it is not as likely to retest this support, but a similar pattern happened with BCG a few days ago, where it bled about 60% under a strong support, before violently correcting to the support level.
i am buying, i plan to sell some at about 609, and save the rest to either break even on, or to sell at about 720-770 for a larger profit.
