One observation i have made of Nifty (i have readings from Nov 2007)
We have had a maximum of FIVE days of consecutive negative closings
Six consecutive days of negative closings has happened only once during the Jan 08 bloodbath.
Today is the SIXTH DAY....
if today it closes in negative, WILL TOMORROW BE A POSITIVE CLOSING (given an imminent/timely due dead cat bounce/technical relief rally from today's lows)....
Only time will tell....
BTW, tomorrow is the derivatives expiry day, today is UPA-Left meet and tonite is the US FED meet.
