Get the app, log in with your Wela account, and start in Test Run with no real money.
Click the button above to get Wela.exe. Save it anywhere, like your Desktop.
Double-click WelaSetup.exe. If Windows shows a blue "protected your PC" screen, click More info, then Run anyway.
Watch it trade with simulated money first. Switch to Live when you are ready.
Windows may warn about new apps from small publishers. Only download Wela from this page.
