@Memo0606 I generally wait for the Americans, simply because the spread is lower then and you can't time whether it falls or rises in the afternoon anyway.
I decide spontaneously what to buy. What looks uninteresting now can be 10% lower again in 3 hours. I don't want to open new positions at the moment, I don't see any point in diversifying at the moment and everyone should be personally convinced that they already own the best shares in the world.
