Why the ARMS/TRIN Index Matters for NSE Traders

The ARMS/TRIN index reveals the true strength behind market moves by factoring in volume, not just price. A low reading (below 0.70) confirms strong institutional buying, often preceding a rally. This complements our volume accumulation and institutional buying guide.

Conversely, a high reading (above 1.30) signals heavy selling pressure and potential market tops. By tracking this index daily, you can avoid false breakouts and align with the dominant market force. It is especially useful during volatile sessions when price alone can be misleading.

📌 Key Insight
The ARMS/TRIN index below 0.70 with rising Nifty confirms strong bullish breadth; above 1.30 warns of distribution even if price is still rising.
