$SPY made an upthrust to 212 before it turn down. and it made a spring on 198.85 support where previous daily swing low was 198.00. Volume is also declining, if SPY show a weak bar, it may break the support for more deeper move. I am watching 190 area support before testing 182 support. There is bulls potential, but I need more reason for going bullish, since the 208-212 resistant area looks threatening.
