On MetaTrader4 (MT4) / MetaTrader5 (MT5), you can display the On-balance volume (OBV), a technical indicator developed by Joseph Granville (USA). The calculations are very simple and easy to understand as follows.
- Current close price > previous close price: OBV = previous OBV + current volume
- Current close price < previous close price: OBV = previous OBV - current volume
- Current close price = previous close price: OBV = previous OBV
Use tick volme instead of volume
Since it relies on volume for its calculations, it is best suited for symbols with available volume data, such as stocks. While OBV is less commonly used for forex symbols due to the lack of volume data, you can substitute tick volume, which represents the number of ticks.
Here we will look at how to add OBV to a chart on MT4/MT5.
Switch between MT4/MT5 tabs to check the steps for each.
Step 1
OBV can be set up from the menu or the Navigator.
Add OBV from the menu
Click "Insert" in the menu. Hover the pointer over "Indicators" > "Volumes" and select "On Balance Volume".
Add OBV from the Navigator
On the Navigator, click on the "+" signs next to "Indicators" and "Volumes". Select "On Balance Volume" and drag it onto the chart you wish to apply it to.
Or, right-click on "On Balance Volume" and select "Attach to a Chart".
Step 2
The setting window for OBV will appear. Set the parameters in the "Parameters", "Levels", and "Visualization" tabs and click "OK".

Set the maximum value for OBV on the sub-window. |
"Levels" tab
In the OBV sub-window, you can display horizontal lines at the specified levels. If you want to add a horizontal line, click "Add" and enter the number.
"Visualization" tab
In the "Visualization" tab, you can set the timeframes to display OBV. As OBV can only be displayed in a sub-window, it will be displayed in the sub-window even if "Show in the Data Window" is unchecked.
Step 3
OBV will be displayed on the sub-window of chart.
Volume indicators
In general, indicators can be grouped into two categories: trend and oscillator indicators. These indicators are designed to focus on price fluctuations. On the other hand, OBV looks at volume in addition to price fluctuations. Like OBV, indicators that focus on volume are classified as volume-based.

Scale by line |
Specify where you want the OBV to show up on the sub-window. If you set the scale percentage to "50" and the scale value to "0", the scale of the vertical axis will be adjusted so that the scale value of "0" will be set at the 50% mark (max value is 100%). |

Set the minimum/maximum values for OBV on the sub-window. |
