From NOV 18 to June 19 (till date) as seen, we can see HIGHER HIGH AND LOWER HIGH. I split this in two parts NOV18 TO MAR 19 and from MAR 19 to JUNE 19 (till date)
Part - 1 NOV 18 to MAR 19:
Index level making HIGHER HIGH AND HIGHER Low and the Strength ( ) also has upward slope, means this up move was with strength support.
Part-2 MAR 19 to June 19 (till date):
Index level making HIGHER HIGH AND HIGHER LOW and Strength ( ) is making downward slope (observe blue lines in chart) , means this up move is not supported by strength.
Till Strength regains, NIFTY is directionless.
Key yet to be identified.
