based on price action you can see how the chart was acting. people reached a point of take profit back at .8637 and then the bears got a hold of the price and dropped this down to .8507 bulls tried to regain confidence and control and reached back up to .85506 they then lost control and retried to regain it but were denied 3 times by .85506. look for them to complete one more 100% retracement at this level for a short position. with a trendline strong resistance level and fibonnaccis on your side, this may be the final stop before heading back up to 8637 range so becareful and watch price to check your take profit. Nadex traders get above that price on a hour to 2 hour contract
