Rule of 52, by the name you must have understood that it has got something to do with number 52. Your guess is correct but this has got nothing to do with price prediction it has got everything to do with time, when price may turn. Up, Down or Sideways all such analysis can be done once you understand rule of 52.
This is just an observation, traders around the world can use this to predict next top or bottom dates. Observations are as follows.
1. Price makes mesure/minner tops or bottoms on 52nd day from previous top or bottom. 2. Price will change current trend and will move opposite or sideways after 52nd day. 3. I won't suggest to trade only on the basis of this prediction 4. After taking trade one can be alert on such days. 5. You can test same concept on your instrument and do needed changes to it.
I am sharing few more charts of different instruments for reference. Have plotted the same on nifty we will see what happens on the projected days by black lines on the chart.
