Bitcoin price may have fallen over the last two days, but the overall trend over the year thus far has been up, and an end to the correction could soon be here.

One crypto analyst has spotted an extremely bullish signal on a Bitcoin price indicator that hasn’t given such a signal since the first-ever crypto asset bottomed out in the low $3,000 range.

OBV Indicator Shows Bullish Divergence, Bitcoin Price Could Spike As a Result

Bitcoin price is amidst a longer and deeper than most crypto investors expected, after witnessing just how fast the crypto asset rose to $20,000 in 2017 and during this recent parabolic rally from the $3,000 range where Bitcoin set its bear market bottom.

The correction first began in late June and is now over two months long in duration. During that time, Bitcoin price has fallen over 30% from $13,800 where it was rejected by the resistance level where the bear market all began.

But that level may soon be broken, as one crypto analyst has discovered a powerfully bullish signal on a USD/BTC chart indicator that hasn’t occurred since Bitcoin rocketed out from the deepest depths of the bear market – never looking back.

Crypto analyst filbfilb, an analyst who nailed various calls throughout Bitcoin’s parabolic rally, says that the OBV indicator is showing the first bullish divergence since the first-ever crypto asset was at its bottom. The last time this signal was seen, Bitcoin price saw over 300% growth from there in a matter of six months.

OBV stands for on-balance volume and according to is a “technical trading momentum indicator that uses volume” to predict changes in the price of an asset – in this case, Bitcoin. A bullish divergence occurs when prices reach a new low, while the indicator fails to do so and sets a higher low.

Crypto analysts and traders use these tools to help them predict where the market direction is going. The bullish divergence on the OBV indicator can be seen on the 4-hour chart. Signals on higher timeframes provide the most weight in any technical analysis.

Another 300% rise from $10,000 would take Bitcoin to double its previous all-time high at $20,000, and set a new all-time high at $40,000. The last time Bitcoin price grew by 300%, it only took six or so months. The leading crypto by market cap at $40,000 six months from now would follow along with the predicted trajectory of Plan B’s stock-to-flow model, which suggests that Bitcoin price will reach $55,000 by May 2020, when Bitcoin’s halving occurs.
