no TLB in today's nearly unchanged RTH session.

But I looked into the asia- and EU-session separately:

Overnight in asia is mostly flat since start of the year.

Overnight during Europe session is mostly negative.

Conclusions:

1.
If one plans to go long SP500 futures, look for a potential pullback during the EU-session

2.
This is not clearly visible in the charts,
but multiple times in the last days a measured move target (based on some RTH move) was hit during the asia session - and afterwards we got the EU-pullback.
