Good Morning.
Resistance Levels are the same as yesterday’s
1930-35; 1945-49; 1958-61 etc…

Support Levels are:
1884.62 (38.2%) and 1866.16 (61.8%) of previous up move. The 50% (not a Fib level) is at 1870.39
There is the high of Feb 10 at 1881.60 which is very close to the 1884.62 (38.2%); so that area could hold the market.
1850 could be psychological level, but it is not a Fib Level.
Below that we have: 1810-1806; 1800-1803; 1730-1728 and 1690-85

Keep in mind that these levels could hold the market but may or may not be reversal levels.
I failed to post the 23.6 Level of the previous move at 1902.22 and that one as you can see is very close to the 1900 psychological level…
