"[Date] - Optional - Colon delimited dates and ranges YYYYMMDD:YYYYMMDD-YYYYMMDD,YYYYMMDD. Requires a symbol be specified."
What does this actually mean? Why do we need 4 dates to define a range? |

Craig - I agree with you that the description could probably be made clearer. I believe the meaning is simply that the optional Date parameter can be either a single date (YYYYMMDD) or a date range (YYYYMMDD-YYYYMMDD) or any combination of dates and date-ranges, separated by colons. For example, "20190620:20190701-20190731:20190908" means "the single date 2019-06-20, plus the date range 2019-07-01 to 2019-07-31, plus the single date 2019-09-08".
p.s. - in the description, the comma just before the final date is most probably a typo - it should be a colon (:). In IQFeed's API commas are used to separate between parameters and are not allowed within the parameter values. The colon character is used to separate values within a parameter (hence "colon delimited").

Yes, this is correct. The text on the help page is unclear. I will have it corrected.
You can specify news from any specific date (20191007) or any date range, which is separated by a dash (20191001-20191007). If you want more than one specific date, or date range, you separate them with a colon: For example: NHL,,QQQ,,10,20191007 (returns stories from October 7) NHL,,QQQ,,10,20191001-20191007 (returns stories from October 1 through October 7, inclusive of all dates in between) NHL,,QQQ,,10,20190612:20191007 (returns stories from October 7 and June 12, but no dates in between) NHL,,QQQ,,10,20190612:20191001-20191007 (returns stories from June 12, and October 1 through October 7) NHL,,QQQ,,10,20190601-20190607:20191001-20191007 (returns stories from June 1 through June 7, and October 1 through October 7) And so forth. You can also have three or more dates/date ranges. Sincerely, Gary Stephen DTN IQFeed Implementation Support Specialist |

Thanks for the clarification Gary.
I'd appreciate it if you could take a look at my other news related question please. |
