What is Market Internals?

Market internals measure underlying participation — advances/declines, new highs, volume breadth.

Formula

TRIN = (Advancing Issues / Declining Issues) / (Advancing Volume / Declining Volume)

Indian market context (NSE)

Reference levels: Nifty 50 at 24,300, Reliance Industries at ₹1,300, Bank Nifty futures at 55,000 (lot size 30). Examples below show how Market Internals shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Market Internals: TICK, TRIN & Breadth Indicators on Nifty (24,300): on the 15-minute chart, combine with session VWAP and 9:15–10:00 liquidity — index market internals: tick, trin & breadth indicators signals misfire on expiry Tuesdays without volume confirmation.

Reliance Industries perspective

Market Internals: TICK, TRIN & Breadth Indicators on Reliance at ₹1,300: daily vs hourly settings diverge around results and ex-dividend dates; note corporate events in journal when market internals: tick, trin & breadth indicators readings spike.

Bank Nifty futures perspective

Market Internals: TICK, TRIN & Breadth Indicators on Bank Nifty futures (55,000): first-hour signals differ from post-14:30 behaviour; avoid standalone entries when banking names lead the move.
