- If you are new user and yet to create a trading account in AutoTrader system, then do it from here.
- Make sure you have a Pseudo Account by the given name and it is live. You can check it here.
- Make sure that you are passing correct pseudo account to the API.
- For excel tools, look at accounts sheet
