BTC is sitting now on a High Volume Zone which naturally acts as a support (39400).
Price acceptance (time + volume spent) within the High Volume Zone will most likely result to a move to the bottom of it (31600)
We also have a COMP from 37900 - 32300. The edges of this zone can act as further support / resistance.
Accepting within the High Volume Zone but bouncing from the COMP High (37900) can lead to a up move to at least 42000.
