Hello everyone. I have installed Zorro but when i'm going to test a script this error appears. What should i do? When i go to the history folder, the files are in.

Is it a custom script or one of the scripts that come with Zorro?
Where is the history folder located? Maybe the problem is related to security permissions in that folder or the UAC

You may also be trying to call an asset by an incorrect name. Check if there are any typos in your script.

Hello and thank you for the answer. It's a Zorro script, the folder is in the Zorro installed folder.

Error 55 means that price history is missing - even if you disagree with the computer. You can download it from the download page and copy it in your history folder.
