Today Nifty opened above 100 points, started falling down and then recovered. The 2 big red candles denote weakening of upside and the red line above shows point of significance. In case you are in long position its time to keep trailing SL on your profit. I think there are roughly 66% chances that Nifty will go sideways or fall from Point of Significance. By placing SL on Profit make sure to exit positions in profit in case price starts falling.
