I have a study to track DOM Stacking/Pulling and a study to track DOM Recent Bid Ask. The challenge I have is preserving the DOM data on screen refresh. I am using sc.IsFullRecalculation to not wipe out the subgraphs on a recalc of the chart. However, if for example, I access the Studies window and hit Apply or OK the subgraphs zero out and start over and the previously displayed subgraphs are gone. I have attached a before and after picture of the same chart. Preserving the previously displayed values must be able to be done since a third party study in Region4 does just that. I noticed the Numbers Bars Calculated Values v2 also resets the values. Any ideas anyone? Thanks! Mike Date Time Of Last Edit: 2024-07-31 00:31:47

It might be helpful to know why you are going into Studies and hitting "Apply/OK"

Because for example, a different study needs a tweak. The point is, when the chart completely refreshes, the currently displayed data is lost. I'm trying preserve the data already displayed as the third-party does. Thanks Date Time Of Last Edit: 2024-07-31 04:04:10

Any ideas anyone? Persistent pointer in combination with STL container Persistent Variable Functions https://en.cppreference.com/w/cpp/container

I did some book learnin' but now I'm looking for a bit of a head start. Does anyone have any source they might be willing to share with me that shows how to implement using a vector to hold and reload subgraph data? Thanks, Mike

Before crawling down the vector rabbit hole, you should first determine whether the value you want to change in your study can be changed on the fly -- without having to change it manually in Study > Settings. If so, your problem is solved: Add code to your study that will do just that. If not, then...

Came up with a work-around. A dedicated chart for DOM data studies with that being overlayed to the main chart. Mess with the main all you want then. Date Time Of Last Edit: 2024-08-01 16:09:37
