I guess it should retrace back a little to 25$ range and then carry on the upward path to 29$. This is surprisingly moving fast so I would see a nice 20% growth soon.
4hr and Daily chart suggests the crossover of 50 and 200 EMA. Also a nice bounce from Ichimoku on the 4hour suggesting a nice support and faith in the stock. JD is a big company and US China deals may lift it up to where it really belongs ie 40$ but i would not be greedy and pull out at 30$ to be honest.
PS. not an investment advice
