Why the ARMS/TRIN Index Matters for Intraday Timing

The ARMS/TRIN index reveals the true strength behind market moves by weighting volume. A reading below 0.7 indicates aggressive buying, while above 1.3 signals heavy selling. This helps you avoid false breakouts and catch reversals early. For a deeper understanding of breadth, see our market breadth guide.

Unlike price alone, TRIN accounts for volume distribution, making it ideal for intraday timing. When the Nifty 50 rallies but TRIN stays above 1.0, the move is weak and likely to reverse. Conversely, a dip with TRIN below 0.7 often signals a buying opportunity.

📌 Key Insight
When TRIN drops below 0.5 on a 5-minute chart, it often precedes a short-term pullback. Wait for it to rise above 0.7 before entering a long position.
