Description
Fixes #7708.
The open interest universe model now requests a seven-day tick history window instead of a previous single trading-day window. This lets it recover the latest available open-interest tick when the selection time lands around weekends/non-trading days, including the February 27, 2023 case described in the issue.
Root cause
The previous request window could start on a non-trading day boundary after timezone rounding, causing the history provider to return no open-interest data even when recent data existed.
