SPY - Hammer Reversal

buying friday's hammer reversal... look to take quick profits near 10 sma and then hopefully re-enter if follow through day occurs... big if. I currently expect the primary downtrend will continue, but you must be flexible in this market. 11.19.12 well, that didn't take long... CLOSED position today @ 139. (2.3% profit) - did leave some for selling into remaining strength over the next day or two...
