The mentioned support trend line is currently near 10,730 EUR, and as long as the index remains above this trend line, the short-term outlook seems bullish. The RSI indicator is in the middle of its zone on the two-hour chart, which ain't helping at all, but it also says, further upside is possible.
However, if the uptrend line is broken, stop losses could be hit, which might drag the index lower, targeting the 10,500 EUR zone.
Alternatively, if the price continues to rally, the resistance seems to be at yesterday's highs of 11,000 EUR, and if conquered, DAX could revisit the current swing highs near 11,300 EUR.
Sentiment still seems positive as many EU countries are reopening their economies, and central banks are still pumping money into the financial markets.
