Following on from my "Broken weekly trend line" idea, here's my updated version. The reason I still think this will occur is that today we had a double top and the day candle as it stand now (20/9 at 18:40) tells me that we're going to test the weekly trend line again twice before it breaks down and this leads me to believe that we're going all the way down to 9797.
Let's see how this pans out! If you like the idea, don't forget to click the like button and of course, any comments are welcome, but don't be rude! :)
