DOM data not starting when chart is attached.

I am working with a couple of newer SC subscribers. They are using DOM Pulling/Stacking on a dedicated chart with the chart being attached. What happens is we have to click on the tab to make the chart active for the PnS data to start populating. Any ideas? Thanks! Mike

What tab are they clicking on? What is occurring if the tab is not "clicked on"? Is the Market Depth data updating? Is this a Trading DOM or a regular Chart? For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Hey John! Attached are two pics. The "tabs" pic shows the chartbook setup in use. There are three charts in use. The one second chart is the DOM data chart. That is shown in the "DOM" pic. What happens is when the chartbook opens the 5-3-0 #2 chart is "active". The pulling and stacking and recent bis/ask studies from the one second chart are overlaid on to the 5-30 and 8-5-0 charts. Until the one second chart is made "active" by clicking on the "1 sec #1" tab the pulling and stacking data does not start populating on the one second chart. Therefore, of course, the pulling and stacking data does not appear on the other two charts. It seems the one second chart needs to be "activated" for lack of a better term to begin the flow of the pulling and stacking data. On my system my DOM chart is detached and begins populating the DOM data immediately on open of the chart book. If the one second chart is not clicked on to make active, the pulling and stacking data does start flowing. Note the absence of any pulling and stacking data on the 5-3-0 chart. The data on the one second chart only started appearing AFTER the one second tab is clicked on. Apologies if I have not explained this clearly. :) Thanks!

Thanks. We understand the situation now. What are the studies that are being used - what is the source study and what study is doing the overlay? For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

The source studies on the one second chart (PnS & Recent B/A) are custom studies of mine. Very basic IMO. I am using the SC Study/Price Overlay for getting the source studies on to the 5-3-0 and 8-5-0 charts. The recent Bid/Ask data is always there. Just the PnS that doesn't start. When I make the one second chart active I do not immediately see numbers in the Bid or ask stack columns. It takes a moment for that to start populating. Are you thinking my study may be impeding the DOM PnS data. Or, my study isn't starting in the "attached" scenario? Everything starts fine in my system even when I attach the one second chart. It's just these systems in NE. I have attached my code for your reference.

We generally understand the problem. We are not 100% clear on all the details and there are some questions but what we need to do is add a function you can use in a study to set that pulling and stacking data is required and that should resolve the problem.

Update to prerelease version 2748 and this is the new function: sc.SetUseMarketDepthPullingStackingData(1);
Call this function once when sc.IsFullRecalculation is true Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

It looks like it could be placed in the defaults section. Correct? Or sc.Index = 0 to run only once? Thanks

Yes should not be a problem to put it in the sc.SetDefaults section.

I could not get this to work after modifying the study with the new function. The code is attached. I put it in the Defaults section. Taking the study out of the equation, the pulling and stacking DOM columns begin to populate at chartbook startup if the chart with the DOM data columns on it is detached. If the chart with the DOM data columns is attached, the only way to get DOM data in the DOM columns to populate is to make the chart with the DOM data columns the active chart. It takes a second or so after the chart is made active to see the DOM data flow. This is not mission critical for sure so please feel free to take your time looking into this. If they are the only ones having this issue then I guess it could be something on their end but we did the standard install etc. and it does work fine if the chart is detached. Thanks, Mike
