The FTSE 100 is currently trading in a sideways pattern, positioned below its November high of 8319 but above the 55-day simple moving average at 8231. It is expected to face resistance between the mid-September and late October highs, specifically in the range of 8326 to 8372. This resistance is likely to limit upward movement for the rest of the year.

The DAX 40 is trading just below its all-time high and has recently broken through its downtrend line from October to November at 19,428. It reached a peak of 19,681 in November, close to its record high of 19,683 from October. If it surpasses this level, it could potentially reach the 20,000 mark, with support expected around the range of 19,566 to 19,547.

The Nasdaq 100 is currently experiencing low volatility after the Thanksgiving holiday, with the key resistance level at the late November high of 21,003. If this level is exceeded, the record high of 21,233 could be targeted. Minor support levels are identified between 20,744 and 20,753, and a drop below this range may lead to a revisit of the uptrend line at 20,655, which is expected to provide support.
