What is OBV indicator?

On Balance Volume (OBV) is a cumulative indicator for measuring volume flow.

OBV is an indicator which can help you to understand whether bulls are buying or bears are selling. Simply it’s showing you buying or selling pressure.

You can measure the volume of any candle with a simple volume indicator on your charts. but, the OBV indicator helps you to see the volume trend better and moreover, To know when “smart money” comes to play.

This indicator first introduced by Joe Granville on his 1963 book “New Key to Stock Market Profits.”

How does OBV indicator work?

On Balance Volume (OBV) is a cumulative indicator that adds volume on green candles and subtracts volume on red candles. Here we show how OBV works with a simple example:

  • Day 1 closing price of bitcoin = $6500.00; volume = 1,315,000
  • Day 2 closing price of bitcoin = $6550.00; volume = 1,370,000
  • Day 3 closing price of bitcoin = $6420.00; volume = 1,210,000
  • Day 4 closing price of bitcoin = $6420.00; volume = 1,105,000
  • Day 5 closing price of bitcoin = $6570.00; volume = 1,360,000
  • Day 6 closing price of bitcoin = $6650.00; volume = 1,430,000

The idea behind the OBV indicator is:

whenever the daily price of the bitcoin goes up, Then OBV increases by the bitcoin volume amount accordingly.

In contrast, whenever the daily price of the bitcoin goes down, OBV decreases by the bitcoin volume amount.

In other words, if the closing price of the bitcoin doesn’t change in one day, The OBV going to show last day volume amount.

  • Day 1: OBV = 0
  • Day 2: OBV = 0 + 1,370,000
  • Day 3: OBV = 1,370,000 – 1,210,000 = 160,000
  • Day 4: OBV = 160,000
  • Day 5: OBV = 160,000 + 1,360,000 = 1,520,000
  • Day 6: OBV = 1,520,000 + 1,430,000 = 2,950,000

OBV indicator disadvantages

OBV is just a volume indicator and you should have reasonable expectations from it.  We pointed out to some of the main reasons why you should be careful when using OBV indicator:

OBV in Highly liquid markets

When you’re using On Balance Volume indicator in highly liquid markets like Forex main Currencies (e.g. EUR/USD) it can’t help you much to identify whether the signal is right or wrong.

The reason is simple, when there is high liquidity in a market there are many buyers and seller for each price. So the increase in volume doesn’t necessarily cause higher prices.

You can compare the OBV indicator performance in Forex with other markets like stock or cryptocurrency, and you’ll find out it’s more useable on those markets.

OBV after breakouts

The volatility of markets can affect OBV indicator performance quite much.  After price breakouts, OBV can give you wrong signals about buyers/sellers power.  Because OBV is a cumulative volume indicator and just one candlestick volume can considerably affect its final amount.

In these situations, you can’t figure out whether buyers/sellers can maintain their control over price after reaching new levels or they just lost control. In other words, you can use OBV indicator before breakouts to see increasing in volume but after it happened, you should be very careful and use other indicators to confirm price action.

OBV in lower time frames

Lower time frames always consist of high volatility which can make price action noisy.

Like many other indicators which can give you wrong signals in lower time frames, OBV could mislead you in trading decisions too. Therefore, it’s better to not use OBV indicator in lower time frames or confirm its signal with other indicators before opening a position.
