For Sierra Chart 2950, using SC Data with QQQ_MBO and sc.GetTimeAndSales(): How are UTP trade cancellations and corrections handled in the streaming Time & Sales records and stored historical intraday data? Are original records removed or amended, are replacement records emitted, or are these messages handled only upstream? If ACSIL exposes a correction, how can a study identify the original trade and determine the corrected trade’s ordering position? Which documentation defines the sale-condition filtering applied before records reach ACSIL? |

It has always been a very consistent, philosophy/policy, that market data trade cancellations and corrections are completely ignored across all data feeds. This has never changed. The only exception, it is order routing to an exchange where if they report a trade cancellation or correction, it definitely will be followed.

For QQQ_MBO using sc.GetTimeAndSales(), which UTP sale conditions are excluded before records reach ACSIL? Does this stream follow the chart's "Include Odd Lot Equity Trades" setting, or operate independently? Please point to the applicable documentation.
