How to see both Bid and Ask prices on chart in MT4?

Usually, MT4 charts display only the Bid (sell) price. However, you can easily add the Ask (buy) price to the chart by following these steps:

Right-click on the chart window.

From the sub-menu, choose “Properties”.

In the pop-up window, click on the “Common” tab.

Put a tick on the “Show Ask line” option. To save the changes, click “OK”.

This will display both the Bid and Ask prices on your MT4 chart.
