We could get a bounce before before we eventually break lower but I think it is a done deal. I can't visualize any upside above 4200 before we break lower. Nothing bullish about that chart at this point. 2nd touch of a trendline is usually the kiss of death.
Minimum target would be the June lows. Depending on a lot of things, we could get a simple double bottom or a formidable crash/downside acceleration akin to those of 1987 and 2008...
