Yesterday (27 Oct) #SPX #ES_F closed at the lows. It is still ranging now. Normally if we are to pullback, it should come quickly from open, but not so yet, thus probably we will sell in Europe session. But do note that 3402-3406 is a valued area of yesterday, there is always a probability we might pullback to there. That will present a low risk short level.
Purple lines 3382 and 3390 are probably R. If you want to trade the pullback you can trade level to level, but as per my plan, the upside (above the blue zone) is limited - 3412 and 3420.
Below support are 3364.8, 3350.8. If 3323.8 hits, it should present a low risk long level.
