What is Fibonacci Extension?

Fibonacci extension levels (127%, 161.8%, etc.) project from retracement swing for targets.

Formula

A = Swing low (start of the impulse wave) B = Swing high (end of the impulse wave) C = Retracement low (where price pulls back to before resuming)

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 Fibonacci Extension shows up on Indian index, equity, and futures books — update to live quotes in your journal.

Nifty 50 perspective

Fibonacci Extension on Nifty (24,300): on the 15-minute chart, combine with session VWAP and 9:15–10:00 liquidity — index fibonacci extension signals misfire on expiry Tuesdays without volume confirmation.

Reliance Industries perspective

Fibonacci Extension on Reliance at ₹1,300: daily vs hourly settings diverge around results and ex-dividend dates; note corporate events in journal when fibonacci extension readings spike.

Bank Nifty futures perspective

Fibonacci Extension on Bank Nifty futures (55,000): first-hour signals differ from post-14:30 behaviour; avoid standalone entries when banking names lead the move.

How to validate

  • Forward-test Fibonacci Extension on paper or sim for two weeks after rule changes.
  • Validate only on trades where Fibonacci Extension settings matched the written playbook.
  • Split results by trending vs range weeks on Nifty before trusting the signal.
  • Require higher-timeframe bias agreement if that is part of your rule.
