2 of the rallies (from Jan 2015 low) that reached up to 0.75-1 median channel of this pitchfork
has retraced 32 and 44 percent. so I think a retrace of 30 to 40 percent is plausible.
with this idea I would expect to 3490 cny
which is also the monthly pivot
and if that doesn't hold then 2960 cny
in usd terms; 530 usd as pivot
and 450 usd as S1 should be good to be long.
