The trend and bias are down so far this morning. Prices found resistance at the former support line on the daily chart and have turn down from there. No real surprise with that, but that does not mean prices will not attempt another push through that support/resistance line over the next few trading days. Likewise, we could see prices turn lower again and push for a retest of the recent lows on the daily chart. Either scenario is a possibility at this point, so we just need to follow the price action while prices sort out their next move. Expect mixed trading at times no matter how the overall day plays out.
If prices are to make a measured move down, that target is down at 6575.75, and that would give us to measured legs as well. Note that there is an overhead gap on the chart as well, and if prices turn and start trending higher, that would be a likely first goal attempt to the upside. That target would be up at 6650.75. Stay with the downtrend until the price action shows you otherwise.
