I've been waiting for January's candle to close for this!
The Heiken Ashi chart smooths out the price in the candles to represent more of an average between candles. What this means is that in a bullish trend the candles are greener and in a bear trend the candles are more red.
As you can see on the Bitcoin Monthly chart the Heikin Ashi chart quite clearly demarcates the line between bear and bull markets.
The Haiken Ashi has turned green. This is very bullish. Yet another bullish reversal pattern. See my profile for dozens of pieces of evidence.
