An idea to short of BTCUSD based of support/resistance levels

BITSTAMP:BTCUSD   Bitcoin / U.S. Dollar
Looking at the 4 hour chart price is traveling in a upwards channel, we can see a significant resistance @9328.60 level, switching to 15 min chart we can see price has bounced off said resistance and may continue lower to support level @7631.47 continuing in the channel. Opinions would be valued.
