Although the current bearish H&S pattern on DAX is not symmetrical i.e. the right shoulder is higher than the left shoulder, however, it still is indicative of a bearish correction to take place; also, this unsymmetrical setup does form a megaphone setup if you draw trend lines extending from the right to left shoulder and from the low at 11'868.84 to the lower low at 11'726.62. (I didn't include the megaphone depiction on the chart because it would become too messy)
Although price has been ranging for a while now, it does seem as if the range is tightening i.e. the top of the range is gradually being pulled lower. Right now the range is between the ATH of 2015 at 12'390.75 and the low of 2018 at 11'726.62.
Thus, it looks more and more that a bigger retracement is coming. Evidence supporting that claim are: price closed below the 100SMA for a second week in a row, the RSI is still below it's bearish trend line and price has remained below the 3% breakout level after it closed below the 2 year support trend line on Aug 6, 2018.
Looking at the RSI, it seems as though it will test the down trend line one more time, contact I presume will be at around the 46-47 level, which was the low of Aug 20, 2018 at 12'245.56. The latter price is significant because it is almost exactly at the 3% breakout level.
A short opportunity would present itself if price were to get rejected at the 12.237/45 level, and the RSI has not broken the down trend line. Short entries could be made with a close below 12'120.65 (low of Aug 13) with stops above 12'240. Target would be between 11'278/20, which is the 1.272 Fibonacci extension level and the measured target objective of the impulse leg AB from the retracement high at 13'204.31.
A close above 12'616 could potentially send price to the 12'840 levels, and then it would be very likely that price would go and reach beyond the high's at 13.596.89, but we will simply have to be patient and wait and see. Also don't forget that starting this week till Oct 14, 2018 the Bavarian elections will be running, thus, causing volatility in the DAX.
