The first step is to join the dollar index server.

In Metatrader (MT4) software, we added American Finger server, whose address is mt.forexua.com:443. We have a new data source by changing MT's tools-options-server settings.

Step 2 Register a new simulated account.

We need to open a new mock account. The new account uses the dollar index server, so that the dollar index data can be continuously transmitted on the chart of the new account.

The third step is to call up the US dollar index-USDX.
