Hello,
im trying to download the volume footprint chart data for ym! or mym form 2023-2026. i was able to use mymm26 CBOT and then switch it to continous futures chart in the settings and then download till 2023. but there are 2 issues. 1 is that there is missing data . like q2 no 2025 just isnt there. the voluume is 1 x 2 on bid x ask for eg. and 2 is that the price is wrong. for eg. showing that market is trading 37500 when it was actually at 3900 .

i used the troubleshooting guide and tried all. ive redownloaded the data etc. didnt change anything. i think im missing some info. not sure what. thanks!

Make sure you re-download the data following these instructions:
Continuous Futures Contract Charts: Re-Downloading Continuous Futures Contract Data

Follow the instructions here to use a larger Intraday Data Storage Time Unit to improve download performance and avoid download failures:
Historical Intraday Data (Missing Data / Download Errors / Viewing More Data): Improving Historical Intraday Data Downloading Performance

And do not use, one of the back adjusted Continuous Contract options:

I did that. nothing changed. q1 and q3 2025 is completely missing. q3 and q4 2024 is also missing. no data at all showing. the data that is showing is a different price, showing market is at 35000 instead of 38000.

is there anything else i can try.

As a test we want you to set the Intraday Data Storage Time Unit to 1 Minute:
Data/Trade Service Settings: Intraday Data Storage Time Unit (Global Settings >> Data/Trade Service Settings >> Common Settings >> Common Settings)

And re-download the data for all contract months:
Continuous Futures Contract Charts: Re-Downloading Continuous Futures Contract Data

And after that provide an image of the chart, by following these *exact* instructions:
