When you make a deposit into your investor wallet in the Social Trading application, it is for the sole purpose of copying trades from strategy providers.
Although you can use your Social Trading credentials to sign in to the Exness website, the money deposited in the investor wallet cannot be used for regular trading and thus will not show up in your Personal Area.
For regular trading, you can create an account in your Exness Personal Area and make a deposit. Learn more about this here.
