Bitcoin (BTCUSD) is witnessing a strong green week, following three straight weeks of flat price action that got many questioning the strength and durability of the rally since the start of the year. A simple indicator comes to give the answer on the 1W time-frame. It is the Bollinger Bands that display a very distinct characteristic during BTC rallies (similarly during downtrends as well).

We call that "The Bollinger Wave" and it is the upper Bollinger Band (blue trend-line) on the 1W time-frame that Bitcoin rides as a "wave" during a Bull Rally. The chart on the left shows the last two such rallies, with the current being the 3rd one as the price has been "riding" the upper Bollinger since the week of January 16.

The chart on the right shows all such rallies since 2010. It is easily noticeable that when such rallies start there is now easy or quick stop to them and they are supported by the Bollinger's Basis (orange trend-line). This is the exact same trend-line that offered the strong rebound of March 6th.

How high the current rally can go before getting exhausted is anybody's guess but two things are a fact: a) It has only just started and b) the Bollinger Basis has risen to 22435 and is now the long-term Support.

So what do you think? Will Bitcoin continue to "ride the Bollinger wave"? Feel free to let us know in the comments section below!
