This is the first time I am doing the Analysis and you can judge me.
Overall looks bearish - If one can see the huge volume and break down. At the support level - 518-517 and if goes down then small support around 502. Chances are it will then reverse but depends upon market and if it further goes down then strong support around 475.
Very Strong Resistance around 543 and if breaks forcefully then can go upto 570.
