As a usual concept, a demand zone is shown.
So if NIFTY reverse from the 50% retraced line, expected targets are shown.
If not reversed, it may go till 61.8% and possible to reverse.
If it moves below the 61.8% line, possible to continue the down trend.
(Note that present RSI is 40.08, which is not actually gives a reverse sign.)
Disclaimer: As usual, it is not a recommendation.
