DOM POC different than Volume POC or TPO POC

Hello. I noticed that the POC for the DOM VbP on Gold (GC) is displaying a different value than the TPO/VbP POC on my TPO charts. This is not the case for other symbols that use different session times (i.e ES) or almost any other symbol. The POC is consistent with other symbols such as CL, 6E, ZF for example of other symbols I tested. Screenshots attached of GC and ES. I have looked at the chart settings for both the DOM chart as well as the TPO chart and noticed that the DOM is set to "Session start time to end" and the TPO chart is set to "Multiple Profiles based on Fixed Time" which is 1 day for a standard TPO chart. This said, the settings for the DOM chart and the TPO/VbP chart are the exact same for the GC and ES examples attached yet the ES POC is consistent between the TPO/VbP and the DOM VbP and the GC is not. I haven't been able to find a good explanation in prior Support Board posts or in the documentation. Thank you Date Time Of Last Edit: 2026-01-18 00:59:56

I'm sure someone from SC will give you the correct answer, just some thought: first at all, I see you're using different settings on your charts: Gold start-time is the start-time of the trading-day and ES start-time is the index cash-session, so there is already a huge difference. So the question is, are your DOM profile's also set differently? If you just want the cash-session, the time would be for ES: 9:30am ET to 4:00 pm ET and for Gold: 8:20 am ET to 1:30 pm ET |

Session times for the TPO/VbP and DOM are set the same and are default settings. If the ES chart is changed to ZF, CL or a similar symbol with session times that start at 1800 EST, the POC is correlated between the DOM chart and the TPO/VbP chart. For some reason, Gold is the only one I have found that has this inconsistency.

Please get us the GC charts so we can take a look at how you have them setup. Follow these instructions, but get us the two charts (chart and DOM): Support Board Posting Information: Providing Chartbook with Only a Single Chart For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Sorry for the delay. The chartbook with the GC TPO chart and the GC DOM is attached. Thank you for your time. |

The reason for the difference is that you have a different "Ticks per Volume Bar" being used in the two charts. The TPO/VbP chart has a "Letter/Block Price Increment in Ticks" set to 4 in the TPO study, which controls the VbP study's "Ticks per Volume Bar". In the DOM it is forced to be a value of 1. The fact that this does not occur on other charts is just luck. Typically a different Ticks per Volume Bar would result in different POC values, simply due to the aggregation of the data and hence the POC point having a different value due to this.
