on the graph mensinsile moving average periods and 200 flat from 2010 to today the prices they leaned on the support of 1.63 (including this level and also supported by the average 21 periods) and therefore very likely to rise in the other 170 are resistors are area 1.65 = 1.67 = 1.69 this should not pose too many problems to prevent a return of prices to 1.70
