There is still a chance that this is a new bull market for ISYS, if the ABC down from 19p is actually only the first part of a three wave correction ie abc, abc, abc, with the ABC seen so far being the first abc.
If so, we get a rally in abc form over the next two weeks or a sideways triangle affair followed by further weakness to the 15p area in further abc form.
Clearly this pattern needs time to develop, and the chances of any high volume action in the meantime are miniscule.
