4h MACD suggests sideways or slow up for the next 24h, after that will come an inflection point.
Is there any reason to use 4h, rather than some other timeframe?
Only that during the last couple of weeks it was a relatively reliable indicator (compared with other time frames).
The inflection point is here. Either start testing major support or form local double bottom and go up in the short term.
It looks like someone is taking advantage of the inflection point, where the market can be turned one way or another with minimum effort,
and using BTCChina to crash. Volume reported by bitcoincharts is greater than Bitstamp, Bitfinex and BTC-E together, so it could be fake.
