i read about this in some newspapers, but sometimes I do believe that there's such thing known as INDEX MANAGEMENT (Spot) done by "smart money" for their arbitrage trades...
these HIGH & LOW values of spot sometimes tell a lot abt the way ahead...
like after seeing today's HOD of spot 4303 (coinciding with 50DMA + 20DMA), i had posted that this indicates profit-booking day...
even on last thursday, GAP down stopped exactly at 3800 spot... again, a nick that we are looking at possible dbl bottom in daily, weekly & maybe monthly charts (still few days left for sept end, though, for confirming dbl bottom in monthly chart)
And I am very glad that our famous "Line Baba" in Part -2 also relies on SPOT levels more.
