Gann analysis time-price matching for picking swing tops NIFTY50

all calculations based on swing high of 17th sept 2020 & swing low of 24th sept 2020. Time windows calculated using range sqrt & both calendar & trading days time windows are there. So we got sign of top 17th Feb 2021 & Nifty went down till 315 degree after resisting 360 degrees gann angles. We expected a reversal after 7 days or 5 bars after start of correction & Finally we reversed on 24th Feb 2021 after exact time interval.
Let's see what happened next.
