Hello, I have a custom study that I use, but whenever I hit refresh on the chart, or change study collections and come back, all the old data erases. How can I change it so the data stays the whole session even if I refresh?

If your study is calculating intra-bar (when live data is flowing) and setting an SG (subgraph) to a non-zero value and that condition is no longer true on bar close, than the historical bars calculated during a Full Recalculation will not detect those signals. If the signals are valid at bar close, then your code should be recalculating those signals on chart refresh when it re-enumerates from bar index 0 to the last bar (sc.ArraySize-1) on refresh/recalculate. |

The study is highlighting large volume trades when they happen at that price on the bar chart. This would not change at the bar close because it would just be a single trade that has already taken place.

You need to do within the custom study, the calculation/detection of these large-volume trades, on the historical chart bars during a full recalculation. Inherently this should just automatically work. How are you determining the large-volume trades?
