Hi SC Team,

I am having some problems with the Study Subgraphs Difference study not updating with new ticks.

Chart A: 5 minute line chart, source is custom .scid binary write ~10 second intervals
Chart B: 5 minute line chart, source is custom .scid binary write ~10 second intervals
Chart C: 5 minute candle chart, source is AUDUSD (SC FXCM intraday).

Note 1: On chart C I have two Study/Price Overlay studies, one referencing Chart A (last) and another referencing Chart B (last).
Note 2: On chart C I also have a Study Subgraphs Difference study, to calculate the difference between the two Study/Price Overlay studies.

The problem is that the Study Subgraphs Difference study is not updating in line with two Study/Price Overlay studies.
The two Study/Price Overlay studies update in line with the Chart A and B last values.
Also a forced recalculate does update the Study Subgraphs Difference study value, but this isn't practical in live trading.

Thankyou.

Screenshot attached

Update: The difference study does update when the data has caught up to the current bar. Please consider this a low priority item.

This documentation may be relevant to the problem:

Otherwise, there is nothing for us to do here and we will not to invest any time on this.

However, refer to the Input Settings for the Study/Price Overlay study to make sure the Inputs are set so that the data being overlaid extends to the last bar in the chart always:

The usual way to do this iis to set Fill Blanks with Last Value to Yes.
