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 Flag Pattern shows up on Indian index, equity, and futures books — update to live quotes in your journal.
Nifty 50 perspective
Flag Pattern on Nifty (24,300): on the 15-minute chart, combine with session VWAP and 9:15–10:00 liquidity — index flag pattern signals misfire on expiry Tuesdays without volume confirmation.
Reliance Industries perspective
Flag Pattern on Reliance at ₹1,300: daily vs hourly settings diverge around results and ex-dividend dates; note corporate events in journal when flag pattern readings spike.
Bank Nifty futures perspective
Flag Pattern on Bank Nifty futures (55,000): first-hour signals differ from post-14:30 behaviour; avoid standalone entries when banking names lead the move.
