Cryptohopper is an automated trading platform where you can automate your strategy based on technical indicators and candlestick patterns. OBV is one the indicators that you can automate with Cryptohopper.
How can you automate it? OBV gives a Buy signal when the OBV value crosses up its moving average (default: EMA) and a Sell signal when it crosses down its moving average.
If you include volume analyses in your trading strategy, automating OBV will give buy signals whenever volume and price are rising altogether.
