I've written a small script to test opening trades on an Oanda demo account. Zorro seems to generate trade opening events but I'm not seeing any opened trades on the demo account. I'm using an access token from Oanda API to get connected through Zorro.

Below is the output I get in Zorro.

I can use the same account to download historical data from Oanda. But not to open trades.
Please advise!

When you see no error messages, the API had confirmed that the trade was correctly opened. For testing, better use the included TradeTest script. It has a more detailed output.
