SPY Short-term supports - Jan 18

Yesterday, the first support zone - 21 EMA (green on chart) - was confirmed.

In case the price loses this zone, the next potential support will be the left shoulder level of Inv. H&S (467.80).

If the price goes lower, then we can expect a reaction from 465, which is ATH.

I'm also considering here Bottoming Support Trendline as potential support.
