The DIX (Dark Pool Buyer Intent Index) measures the percentage of dark pool volume classified as buy-side. A higher DIX suggests more aggressive institutional buying activity happening off-exchange, often before visible price moves.

• ▲ DIX > 50%: More than half of dark pool trades are buy-side — potential institutional accumulation.
• ▼ DIX < 50%: Sell-side dominates — possible distribution or reduced institutional interest.
• ↕ Divergences: DIX rising while price falls may indicate stealth accumulation. DIX dropping during a rally may signal hidden distribution.
