Was studying some historical falls to draw some meaningful patterns if any, let's take 2000 dotcom crash...Nifty fell from highs of ~1800 to nearly ~850 i.e. 50%+ down...and initial falls were not as severe as currently what we are witnessing + it had multiple pullbacks (1/n)
(2/n) RSI gave multiple oversold signals, infact premature and after each signal it kept falling 15-20% more...again with multiple tiny pullbacks...again note that to breakeven 50% fall you need 100% upmove....200 WMA were meaningfully broken..now let's take example of 2008
(3/n) In 2008, from highs of ~6250 nifty fell to ~2250, almost 60%+ fall...again with multiple pullbacks & some really sharp moves at the end of fall...again RSI near oversold zone multiple times..200 WMA broken meaningfully..remember to recover 60% fall you need ~3x to breakeven
