To keep the forum searchable, a good topic title should summarize the question. Like "X-period EMA of Indicator in C# code" compared to a somewhat lifeless "Question - Indicator". Thanks for marking your topics with "Question" but it's not necessary: most of the topics here are some questions inherently.
