Clear regression channel on BITSTAMP:BTCUSD H4 chart. Looking for short trigger if $21400's is met but fails to hold. Taking profit at channel mid and channel low at $20000 and $19300. Invalidation is $21800 break out of channel and hold. Happy to re-entre trade once price re-enters channel. Take note of 12 and 21 EMA's compressing and rolling over for confluence, in addition to the Stoch RSI cresting back downwards.
