Hi! I have a question about the SC Historical Intraday Futures Data.
data from various data feeds (bid/ask) is very different.
I can not verify the accuracy of the data from SC Historical Intraday Futures Data and from other datafeeds (historical and real-time)
I want to know how much I can trust the data from SC Historical Intraday Futures Data by parameters:

1) bid/ask
2) volume in tick/ volume at price
3) price

p.s.
I understand that SC do not datafeed and are not required to provide data.

I asked this question of technical support but has not yet received a response

maybe someone user knows the answer

I think Sierra Charts (SC) is using Barchart.com data for Historical & Intraday.. You might want to look into accuracy of Barcharts.com data. Note, they provide the data with their higher end packages.
