Post From: docs for Open Interest wrong/flipped for descriptions of daily Historical vs IntraDay

To answer the first of these questions rigorously, I pulled from IQFeed both through SierraChart and
through a non-SierraChart application to have an independent control to compare to Denali data.

What I concluded about the Historical (daily) bars:

The IQFeed and Denali Open Interest match, and further that identical number is what is shown on the Historical (Daily) bar's Open Interest.

To repeat, the Open Interest on the Historical chart is correct.

Therefore the number of trades study, shown on the Historical (Daily) bar, is wrong.

To give a specific example, compare the number of trades and Open Interest for
yesterday, 2022 December 20 on a Historical (daily) chart:

Open Interest, from Denali, though SierraChart v2439: 1,976,545
Open Interest, from IQFeed, through non-Sierra application: 1,976,545

Number of trades, from IQFeed, through non-Sierra application: 1,019,601
Number of trades, from IQFeed, through SierraChart v2439: using History (daily) chart: 1,976,545 << wrong, copies OpenInterest number


Instead of computing the actual number of trades, it is apparently just repeating the daily Open Interest number.

This happens on both IQFeed and Denali, so it is a study computation bug, not a data feed issue.


The second question, about the studies on the intraday daily chart, remains open for SierraChart.
