Can sellers defend 0.287 on $SPX for a short?

I'm watching the 0.2848–0.2873 zone on the 4H. If it holds, I'd rather wait than chase a washout.

Why I care:
• 4H price 0.286 sits below EMA50 0.344, so the trend is on this side
• Stop 6.4% away, TP3 10.2% away, that's 1.6R if TP3 gets there
• 1H RSI at 19, already washed out, I don't chase here

🔴 SHORT
Entry: 0.2848–0.2873
TP: 0.2751 / 0.2678 / 0.2569
SL: 0.3043

Plan, not advice.
