Hi. I'm new here, so please forgive my newbish question. I have tried to solve it myself with wealthscipt programming guide and searching the forum but no success.

Basically I want to use an external symbol csfb, which is a sentiment index. I have created the dataset myself via ASCII, it has date and close fields and works fine when the scale is set to daily.

However, when I try to use intraday scale, this code won't run with the attempting to deserialize an empty stream error.

How do I make the daily updated external index usable for intraday trading?
Thanks.
