1. A new downtrend is established (lower highs) from the 1.1$ high (see upper green line)
I don't see any down trend, the market is just undecided after huge jump to parity, moving in 0.9-1.0 range, without significant overlap of any trendline which you (correctly) identified.
2. Volume trend is down: rises are accompanied with lower volume than declines
Better explanation - such big volume almost does not move the market. There was big support on 0.9 which absorbed whole sell entry. You can compare today's situation with the large sells few days ago. +50% volume moved market in many times bigger fashion.
3. MACD indicator is in bearish territory: blue line below pink line. As long as blue line does not cross pink line, we are in a downtrend.
MACD is just a dumb technical indicator based on moving averages and it is just saying again "we are in the correction" by another words. I don't have enough courage to say "market is bearish" based on crossing MACD lines
.
4. RSI is pointing downwards and has more room to sink before it gets oversold. When it hits 30, we may see a trend change.
RSI is fine indicator, but mainly works on markets moving in the range. In trending market, which Bitcoin surely is (except long sideway move in December), RSI will show only irrelevant mess. You can see that RSI is on the same level as for whole November and December...
Finally, I think that we cannot predict anything in current situation for now, because the technical analysis says that both sides are possible. Saying "It will go down and if not, it will go up" is useless. The better way is to say "I don't have an idea, because market looks undecided right now".
