SDT continues to look steady on the 4-hour chart, trading near 680.59 while the mark price is around 679.30. The 24-hour high comes in at 682.78 and the 24-hour low at 677.87, which shows that price is staying close to the top of its recent range. The chart structure is impressive because it reflects a strong advance from the mid-650s, followed by a clean breakout into the 670s and then a controlled grind higher toward 680. Instead of sharp rejection, the market is showing repeated small candles and shallow pullbacks, which usually points to strong underlying demand.

One of the biggest positives here is how USDT handled its move after the breakout candle. Rather than instantly fading, price held above prior resistance and turned that zone into support. Since then, the chart has formed a stable upper-range consolidation between roughly 677 and 682. That is often the kind of behavior traders watch for in trend continuation setups. If buyers manage to reclaim 682.78 and break cleanly above it, momentum could build for another leg higher. On the other hand, if price slips below 677, the market may rotate into a deeper short-term pullback. At the moment, SPYUSDT still looks firm, controlled, and technically bullish.
