Yesterday session. Reverse engineering, Hindsight analysis, Post mortem analysis or whatever-you-call-it analysis. There was only a signal about 2.5 hours after the US session opened. Both YM and Russell 2000 moved in tandem. Note that since 27 Jan 2021, YM day range has been shrinking day by day. Not a great day for trading actually.
most likely today will also be a not-so-great-day to trade due to its decaying day range. hopefully, there is some major news/trigger to move YM decisively. all the best mister.
compare it with Natural gas (during the European session) and you can see a very very very huge difference.
