Hello all. I have a question. I wrote a code. I tested it on USD/JPY. But there is an error on other pairs of currency. Error was "USD/CHF price history missing". How can i fix this problem?

Head over to the download page:
http://zorro-project.com/download.php

Look under Historical Data Archives section and download the price history you want. You will have to unpack the downloaded archive file into the History folder in the main Zorro installation folder.

without source code ...

try:

asset("USD/JPY");

in your code

Your suggested link is not bad. Because there is only few currency data with t1 format. Indeed i need all currency data with t6 format
