POW! YS1s finally put in a decent bounce after holding the last several days. The lows of the past few days on ES at 1864.50, 1866.25, and 1865.75 told you YS1 at 1866 was being bought.
In addition, NQ could have broken after the news from AMZN, but it too found support on its YS1 with the low of 4129 just 1 point (!) from its YS1 level 4130. BTW, if you haven't seen already, I've been talking about these levels for days.
Stay tuned for the likely test of the February pivots.
