Data center sector stocks are flashing technical warning signals lately. Looking at $IREN, $BITF, $CLSK, and $GLXY on the charts - gravestone dojis keep appearing, and that's worth paying attention to.

At major resistance levels or market peaks, these patterns typically signal bearish reversals. But when we're already in downtrends? The picture gets murkier. What's probably happening is overhead selling pressure testing resistance zones repeatedly, while fresh buying interest stays thin.

These aren't necessarily reversal candles in traditional textbook terms. They're more likely showing us where the supply wall sits - each bounce gets met with sellers, no follow-through demand. In other words, traders are testing but not committing. When you see this pattern across multiple ticker symbols simultaneously, it usually suggests sector-wide hesitation rather than individual stock weakness.

Keep an eye on volume dynamics when these patterns repeat - that's where the real conviction shows up.
