Post From: Market Statistics historical backfill after April 25, 2019 calculation change

No. This would be impossible to do:

When Sierra Chart currently serves historical Intraday data dated before April 25, 2019, was that older history retrospectively recalculated using the newer algorithm?

This looks like the same question. So the answer is no:
Also, if the Sierra Market Statistics calculation was subsequently refined after April 25, 2019, were earlier historical records recomputed after those refinements?
