Nifty and Fib

In my pursuit of learning, I found these Fib retracement levels. 50% retracement has already happened once and from the way external risks are emerging, it does seem that another 50% retracement is on the cards from ATH. Please critique, share feedback, comments. This is my observation as part of my learning and doesn't qualify as a trading or investment recommendation.
