Probably short around 700-720
Looks like a small correction is due. Dow theory suggests that the current short term uptrend is weak since volume must confirm trend. Possible Elliot-wave confirmation?
We a see a double bottom also so good chance it might be an elliot wave start
Long in green area. Close in red. Yellow lines are same length so might be indicative of next bottom in a few hours. P.S: Thou shall never short btc
