His record high is now just under 15,803 points.
The M-Dax gained 0.5 percent to 34,192 points.
For the S-Dax it went up by 0.6 percent.

How high will the Dax rise?

On the underside, however, the air becomes thinner.
Above the current record, further gains of up to 15,775 and 15,850 points would be the result, it said. At the same time, the experts warn of a significant correction at this level. The 16,000 mark would be achievable if the index passed the hurdle at 15,850 points. In the event that the Dax should slide below 15,600 points, this could lead to a small sell-off and initially cause the index to drop directly below 15,501 points.
