$BMNR pinned right under resistance — dealers holding a tight $22–$24 range this week, closing at $23.85.

But 9/18 tells the real story: range widens to $21–$25, and that $25 wall gets way heavier.

This is classic pre-expansion compression. When options structure tightens price into a narrow band, it's storing energy. The heatmap shows dealers building gamma at $25 — that's your magnet and your ceiling.

Setup: Watch for a break above $24 with volume. Confirmation comes if it holds above $24.50 into the wider range window. If it fails and drops back under $23, you're looking at a retest of $22 or lower.

Invalidation is simple: a close under $22 kills the setup and opens $21.

Tight now, room later — that's how dealers set the spring before the move.
