If the index rises continuously for two periods, then the market is said to have given ‘bull’ signal. And if index falls in any one period then the market is said to have given ‘bear’ signal. The total ‘bull’ signals for both the indices exceeds the total ‘bear’ signals for both the indices by
5
Bull signals in BSE = second period to sixth period = 4
Bull signals in NSE = first period to seventh period = 5
Bear signals in NSE = First and eighth period = 2
Bear signals in BSE = Second and eighth period = 2
∴ Required difference = ( 4 + 5 ) - ( 2 + 2 ) = 5
