DAX Overbought but eyes are still on 13000

Using 2 hour bars you can see 2017 performance and a regression channel that puts the steady rally higher into a relative context.
Each time price reached its upper channel it pulled back within two weeks. The pullback is around 3%.
But with 13000 a key level only 2% away, we could see a swift leg up before pulling.
Idea; sell 3m calls at 13000 or set sell limit order at 13000.
