It could be the day trader's dream if the movement was decisive / nice / smooth / curvy down - trader earns $$$ up - trader earns $$$ again down - trader earns again up - trader earns $$$ again unfortunately the movement was jerky/spiky/not curvy eediaaaa!!!!
Looking at the SPX cash chart, the big gap down Monday should fill back to Friday's low and maybe the close at today's open. The fact that the recovery hasn't been a typical "V" and instead has been four choppy days to back fill the gap, I wonder if the whole week isn't a "bear flag" and that once the gap fills, we go down to end the week. Maybe head all the way to last week's low?
