as you say,you don't know that much about charting but i reckon the gap you mention being from months ago is not a 'target'/support level much at all.
AOE is being subjected to general global market factors along with company specific 'doubts'.It's fallen decisively out of a six month range,a top and one has to make your own individual decision as to whether to hold thru the coming 'thin'.
happy trading.
