SC version 2270-64
US equities data feed

I must have somehow corrupted my chart.
I used to have `High/Low for Time Period` displayed on a 5min bar period for US equities.
Worked fine for weeks.
This morning I'm noticing it is not rendering the study anymore.

* the study still exists in my chart studies list
* the study is not hidden
* if I click Edit -> Delete and Download All Data, the study will reappear, but is missing data in certain places
* if I switch symbols or hit Edit->Reload and Recalculate, the study disappears again.

What could be going on?

Update: it appears this behavior is somehow linked to the `Number of Days to Calculate` setting.

The chart is displaying 4 days.
If I set `Number of Days to Calculate` to 3, and reload the chart, the High/Low study will disappear.
If I set the `Number of Days to Calculate` to 0, the High/Low study will draw as expected.

Here is a GIF demonstrating this behavior.

I did perform an SC platform update last week, I wonder if that has anything to do with this new behavior?

We do not see anything wrong. But what we think is happening is that you were looking at a day in the past (such as June 25) and when you set the Number of Days to 3, then it counts backwards and includes the weekend days, therefore it is only going to calculate the data for Saturday, Sunday and Monday. Since there is no data for Saturday and Sunday, there is nothing to display. If you want to display the data for Friday June 23, then you would need to calculate 4 days of data.

This is specifically stated in the documentation for that setting here:
Previous/Period OHLC-Variable Period
