SEems like good support around this $529 area and also this $521 zone
Otherwise I think $500 is the good place to buy or cover shorts
Perhaps the high volume with long candle today might provide some strength to break supports.
Not to mention it looks like the diagonal support line is broken.
I guess this might depend where the stock might head on monday. If it heads up then maybe then perhaps this trend holds.
But if it heads down and breaks this $529 zone. Might be good to short with safe target of $520. more aggressive target could be $500 (a nice round number). :)
