Step 1: Installing MT4

　MT4 is provided by securities firms or FX asset management companies as a trading platform, and you can download and use it by opening a trading account. Because there are settings specific to each brokerage, basically you cannot use the MT4 client downloaded from Brokerage A with a Brokerage B account. However, the basic usage and MT4 folder structure are the same, so you can use the same EA at any brokerage.

To create an EA, you also need MetaEditor, which is installed with MT4. If MT4 installation is successful, the MT4 icon will appear in the application list. Figure 1 shows the MetaTrader launched from Rakuten Securities. To create an EA, first call up the Tester from the top menu tab (red circle). Inside the Tester window there is a button called Expert Editor (red box). This is the button to call up MetaEditor.
