I trade the Asia session and at times the Europe session, although the latter messes up my sleep schedule being in the US,
EST.
You are for the most part correct about price levels and how things move. The pace is much slower than the the US
RTH session and that's a good thing.
I look at it this way, @ 2000HRS (All times EST) another major market opens (Japan) and the US (/ES specifically) will follow that market typically within levels that have been set during the day, RTH session.
In addition the /ES will follow our (US RTH) prevailing trend. The /ES trend can
reverse, at least temporarily, if the Asia markets show to much weakness, but for the most part the
support/resistance levels during the day will hold. At 2115-2130HRS the next set of major markets open (HK / China) and the same holds true. Often after the Japan move, the /ES will consolidate and then move again with the HK and CNY market open.
Same is for the most part true for the Eurozone session, @ 0200HRS, EST another market opens and @ 0300HRS, EST, the "Big Dog" of Europe opens (Dax) and again we follow their movement. If you follow the global markets closely, you'll see patterns and rhythms within the /ES that form, retrace and oscillate around the
S/R levels.
Many people discount the
ETH session, but there's plenty of opportunity there to make $$. One word of caution is due to lower liquidity news events can trigger big down moves (think Brexit, Trump election, Syria bombing, etc.).
I occasionally trade /CL and /GC in the
overnight, but typically do this in the 1800-2100HRS time frame and mainly if the /ES isn't moving or I missed the /ES move.
