Connecting a Live account to a SIM account "associates" your simulation user with the customer details Saxo bank has available for you. This has a couple of advantages, as you can directly create and manage OpenAPI applications in the Live environment and because your SIM account is linked to a "real" person, the OpenAPI can provide delayed market data for all products in the SIM environment.
A default SIM account will only be able to fetch prices for Saxo Bank's own instruments (Forex crosses like EURUSD, USDJPY, etc). In order to get delayed market data for other instruments in the SIM environment, you need to associate your SIM account with a 'real' Live account. This will authorize your SIM account to receive delayed prices for instruments that would otherwise be restricted.
Note: Live accounts must have funding in order to be connected to a SIM/Demo account. If it is not funded, login will fail with the message "Your account is not activated for this platform. Please contact Customer Services."
Step 1 - Go to the applications page on developer.saxo.
Step 2 - Click Live apps.
Step 3 - Log in the with credentials of the Live account you wish to connect with you demo account.
After logging in the demo account is now connected to the live account and inherits the instruments that live account have access as well.
The Applications page now allows for creation of OpenAPI apps directly in the Live environment.
