Hi,
I am trying to test Zorro 1.66 in a MT4 demo account from IG and the Z1 script.
I get the next error messages:
Error 033: UK100 missing in INITRUN
Error 011: Function ATR called with invalid parameters (no price)
Error 011: Function RSI called with invalid parameters (no price).

Anybody has an idea about these errors?
Thanks

Go to http://zorro-project.com/download.php
download all the zip files in the Historical Data Archives section of the webpage and unpack all of them into the History folder in main Zorro installation folder.
This should be enough to get started. Later you will have to figure out how to obtain more recent price data. Read the manual which you can find under the "Help" button in Zorro, it will help!

Thanks!

I have all the historical data from the downloads page and these errors persist.

Question: did you complete the following task?You might want to learn how to acquire fresh data, using Zorro.

And it's not sufficient to just download the historical data. You must also know to copy it into the right directory. Or else pay a support ticket to get help with that...

The historical data is necessary for trading or just for testing purpouses?

For live trading, historical data can be used for lookback. Without it, you would have to accumulate live data for lookback instead. This will delay your entry into the market. Unless you’re doing micro-timeframes, you will likely want historical lookback.
