Pattern is completing a zigzag pattern. b-wave can retrace maximum 61.8% of the a-wave that there is an important support line exist in this level, But we also have an important support line in the 38.2% level. it is possible that price only reach to the 38.2% level and then return. the best trade is to wait for 38.2% line to touch and then open a long position. take profit would be a little lower than the resistance line and stop lost would be a little lower than the 68.2% support line.
