Hello,
Given (selected) day must be present in your quotation database.
The default parameters require you to have database that goes back to 1990.
Also I *strongly* recommend to read the article from TASC before applying the code.
The dates used come straight from the article and there is a lot of background there
that makes it MUCH easier to understand the code.
Best regards,
Tomasz Janeczko
