EMA

[Tesseract_Finte]

In a publish/subscribe model with an upd:{} performing a .u.pub, what would be the best practice to wrap a 20period ema on the published data as you will need the dataseries before the update and there can be multiple records with multiple symbols in the upd. Many thanks.

Found the answer, subselect, clean, and simple.
