It is seem BTC have strong support on ema 200, and make a rebound. Previous analysis, i've told the signal was shown the weak trend, but if the candle break or cross over the ema10 and ema21, then it will be new bullish signal.
The second indicator below the volume indicator show the green dot (red arrow), which is the good bullish signal. If we see the TF 15min, there are a momentum of the bullish trend, after cross under ema10, ema21, and ema50, then it make a pullback. The demand is over the supply!
