Here is a screenshot of one of my paper trading accounts for trades that executed today.

And yet when I look at the Positions section, it shows no open positions. Both in the window and in the text summary at the bottom of the window.

Any idea how to explain why these two windows aren't lining up...?

Maybe they have been sold?

Anyway, there's not enough detail to tell.

I literally turned on half of those strategies this morning. Today was their first day of trading, so any positions in the trade history have to still be open. And I don't see any kind of sell trades in the local history either.

Restarting WealthLab brought some of the open positions back, but not all of them.

What other information do you need?

Nothing else, thanks. On second thought, I realize that you may be dealing with a known issue with the Accounts tool which affects multiple accounts i.e. Switching between Live and Paper Accounts causes positions to disappear

According to the Open Issues list, the workaround for Paper Positions not displayed in the Accounts tool may be to:

1. Restart WLP.
2. Open the Accounts tool and select a Paper account. You'll see your Positions.
3. Now Log in to Fidelity. Avoid selecting a live account, otherwise back to step 1.

Making no promise that it's going to work out in your case, though. This is still being investigated.
