Its a precarious level with both scenarios of break and rejection equally possible.
& Momentum seem to favour a break upwards.
Pay attention to NIFTY trends and before taking trades.
Go Long above 590 for 605,620 with SL at 575
Short it below 565 for 550, 545 with SL at 575
P.S The levels mentioned are long term supports and resistance on monthly charts. I always prefer rounded-off values!
