Seeing intraday missing price data gaps in the NQ, MNQ, ES, MNQ files for March 2020 where some volume is showing, but the price data is not showing as in the attached chart example. Prices are showing before and after the intraday period of time with the issue.

Redownloaded the 2020 data following instructions:
Continuous Futures Contract Charts: Re-Downloading Continuous Futures Contract Data
Historical Intraday Data (Missing Data / Download Errors / Viewing More Data): Retrying Downloading of Intraday Data

Downloads were "Complete".
Retried with both Date Rule Rollover and Volume Based Rollover.
Tried both Load Data Limiting Method Days to Load (2000) and Load Data Limiting Method Date Range.
Maximum Historical Intraday Days to Download set to 3000.
Number of Stored Time And Sales Records set to 100000.
Tried with 1 minute bar instead of 5 minute.

Same issue appears on all 4 symbols in March 2020 and did:
Global Symbol Settings: Update Symbol Settings

Here are the dates/times of when the price gaps appear:

The period you are talking about was from the beginnings of covid and, rather than a problem with the data, you are seeing the result of the price limits being hit.

User431178, thank you for the response. However, don't believe these are limit up/down trades. The limit triggers would not have been hit with the data I've received and the way it's being displayed on my chart.

Sierra Chart Support, could you confirm or suggest what should be done?

The image you posted is a limit down scenario, that is why is does not trade any lower, but can trade higher.
Bear in mind that the price limits were lower then than they are now (for example 5% during ETH vs. 7% now).
You can even check the calculation yourself and see that it is down 5% at that point.

I all but guarantee you that what you seeing is due to price limits, if someone shows otherwise then I'll eat my hat.
