I HAVE PREPARED THE CHART FOR THE NIFTY 20/06/2019 EXPIRY . AFTER A FALL OF NEARLY 151 POINTS NIFTY ON 17/06/2019 , THE RSI IS INDICATING "OVER SOLD" , SO ACCORDING TO ME IT WILL TAKE A PULLBACK RALLY IN UPWARD DIRECTION AND THE RESTIANCES ARE SHOWN IN CHART, THAT IS 11731,11790,11850.... IF IT FAILS TO TEST THE ABOVE RESISTANCES THEN U WILL SEE A FALL AND SUPPORTS ARE SHOWN IN CHART, THAT IS 11645,11580,11520,11475...
