I don't trade with a lot however the dom/tape seem to freeze up after a burst of volume in ES. The entire platform freezes up for 1-2 seconds. Any suggestions would be welcome to help keep things efficient. I've reduced loaded data and increased refresh rates on charts since I don't really use them for anything other than reference. My computer has 64GB Ram, Intel Ultra 9 185H processor. I have the following loaded: *30-minute chart, 6 days loaded with TPO and value area of volume displayed on TPO, current price line, updating 250ms *5-minute chart, 2 days loaded, no indicators updating 100ms *Tape from the 5-minute chart, 1000 records (just time, price, volume, no grid, scroll or highlights) *Dom, 1 day loaded with level 2, price column, recent bid/ask volume updating at 15ms I wasn't sure if it would be best to have TPO in a different chartbook and only open when using. Currently the 5-minute chart is displayed and 30 minute with TPO is on a different tab. Thank you for any suggestions. Date Time Of Last Edit: 2026-05-29 07:55:52

I've looked through all the documentation. Yep, missed a few things.... Sub-integrations and few other things. Thank you for the help.

I put the TPO on a sub-instance and that cleaned it up a lot. Something I cannot figure out. Is it best to add the tape from a dom or from a chart? Today after the burst of volume in ES everything froze up and the platform disconnected entirely and then reconnected. It's been bottlenecking somewhere, I think. I decided to pull my tape from my dom and set the refresh rate of the chart to 350ms.. From one instance, I'm running 1 chart, 1 day of data loaded refresh rate of 350ms now and dom/tape updating at 25ms with 1 day of data loaded. This is far from a slow computer. Not quite sure what caused Sierra to disconnect from data after the large amount of volume that came through. Any ideas or suggestions would be welcome. |

Increased the refresh rate on the dom to 40ms that seemed to clean a lot of it up again. I'm not sure what's normal for a refresh rate on a dom. Chat GPT/Google seem to say around 40-50ms and conversations I had with Ninjatrader said theirs updates at 50. So, I'll try that. Just posting this because I'm sure someone out there is new to setting refresh rates and management of everything. Suggestions are welcome. Date Time Of Last Edit: 2026-06-10 16:35:05
