Post From: Delta and Volume at Price Data Changed After Market Close

As we noted, depending on how you have the "Cumulative Delta Bars - Volume" setup, when you reload the chart, you can end up with different values. This is especially true if you are not resetting at the trading intervals, but developing over the entire chart. The reason for this is that the chart will continue to add days beyond the number that you started within initially, until the chart is reloaded. When you changed service, you are forcing a reload of the chart, so you would probably end up with a different number of days for the data, which will give you different "Cumulative Delta Bars - Volume".

Even if you are resetting the start of the "Cumulative Delta Bars - Volume" at a trading interval, then you may still end up with different results based on differences in the charts for the different symbols that are used between Rithmic and Teton. For instance, if you changed the "Session Times" from the defaults set in the Symbol Settings for the Rithmic chart, then you changed to Teton, the symbol is changed and the default Session Times are loaded. This would give you different Session Times resulting in different values.

And there are a number of different Chart Settings that can affect this just due to changing the symbol.

If the charts are setup the exact same between the two services and you are still having an issue, then we would recommend redownloading the data for boh charts and seeing if that resolves the issue. Maybe you were missing some small amount of data that lead to differences.

From there, you would need to look at both charts and see where things diverge and what is different at that point. Again, redownloading the data would be the solution.
For the most reliable, advanced, and zero cost futures order routing, use the Teton service:
