Sierra Chart does support milliseconds but it uses them as a counter for trades within the same second.

So really the effective resolution is just down to the second.

Charts do display milliseconds, but chart bars cannot be based upon milliseconds.

Individual trades are time stamped using milliseconds, but they do not represent the actual milliseconds. Only a counter.

I don't understand. At ACSIL Programming Concepts: Accessing Milliseconds

The internal value held within a SCDateTime variable may contain a millisecond value. For example, when a chart is set to 1 tick per bar or when the chart bars are not based upon a fixed amount of time, like when they are based upon a Number of Trades or Volume, the starting time of the bar may contain milliseconds.

Therefore, the sc.BaseDateTimeIn[] array Date-Time values can contain milliseconds.

Use the SCDateTime::GetMilliSecond() and SCDateTime::GetDateTimeYMDHMS_MS functions to get the millisecond

So are you saying that we would get a sequence number masquerading as a millisecond?
Thanks.
