While not all GLBs (green line break-out) work out, they are worth monitoring for a low risk entry. If I bought ADBE now (weekly chart below), I would exit immediately if it closed back below its green line. My loss would be about 5 points. Always set a real or mental stop loss and calculate your risk before entering a position. Be sure to check out the table of the performance of selected recent GLBs by scrolling down on this page.
