The low from one month ago hasn't been tested for the second time yet, that's under $300. Only if that holds, then the bottom is in.
Not necessarily, a double bottom on the right scale will do. To ensure that 275 was THE bottom the market has to break resistance at 420$ and push to about 470$.
Then it should be high enough that the corrections that will come will probably build a double bottom and not break major support.
Anyway, soon the 4h MACD should be crossing, so I'm expecting to see a bit of a pump later today.
