Principle of convergence in Fibonacci

If we take two recent swing lows and swing highs and draw Fibonacci Retracement levels for getting a clear idea of possible retracements then there are following possibilities.
1. Nifty has two retracement levels in close proximities, which coincides with each other.
2. First Retracement level of 18030-18080 is already completed. If Nifty Sustains, will move up.
3. If Nifty breaks this level of Retracement, then it might lead to next retracement level of 17480-17576.(buy Put or sell Future)
