As we finish this week in positive territory, we also approach the important weekly trend line. A pullback here is likely, until the dip buyers pile back in. A break and hold on the daily above the trend line would suggest further upside is imminent, thus being a buy signal. With minor resistance areas along the route we can expect to re-test 2015 May highs. Failing to breach the trend line would send the market plunging back towards low 17000s.
