Nifty -Inbuilt or Accidental

Nifty confounds both bulls and bears at the same time. In the last 50 days nearly 20% moves. What is in it?.. For education purposes, if we see the first ATH was very secular inclined bulls not much of abruption. The Subsequent fall is quite orderly around 12%. The rise is on the back of large bulls candles moving in quick succession with similar 12% upmove (dont confuse that market remained where it is). The high printed is 2% below the previous ATH. The fall we witnessed till last week is interestingly 12%. Will the current rise be 12%? if yes can we assume the new high would be 2% below the previous high? Please note 12 is very important numerical number and has lots of significance. Lets wait and see. Casual is more clear than a Computer Eye.
