I'm not getting that problem here, so let's find out what it is.

- Make sure that you have the latest Zorro version 2.44.4, the release candidate.
- Select your Oanda demo account and run the TradeTest script. Open and close some positions. If the problem then still happens, please post the log.
- If the problem only happens with your script, but not with TradeTest, please contact Support. They will then look into your script and try to reproduce the problem.
