If I set the chart bar to be tick level, does sc.BaseDateTimeIn[sc.Index] contains millisecond for each tick?

There are milliseconds, but the milliseconds just acts as a unique counter.

More on this, from Intraday Data File Format: s_IntradayRecord Structure Member Descriptions "When writing tick by tick data to an Intraday data file, where each tick is a single record in the file, and multiple ticks/trades have the same timestamp, then it is acceptable for the Date-Time of the record to be the same timestamp as prior records. What Sierra Chart itself does in this case, is increment the millisecond portion of the Date-Time to create unique timestamps for each trade within a second." Sierra has stated elsewhere that they do intend to start supporting real millisecond timestamps some time this year. Even 10ths of a second would be an improvement! But clearly it's a big project technically. Merlin |

It is not a big project, it just requires numerous small changes in many places and tremendous attention to various details and it has to be done just right.

Understood. I've actually developed some indicator code that makes use of the current Sierra false-millisecond timestamps. For example, by knowing the total # of trades that occur within a given second on a fast #-of-trades chart, I can synchronize an overlay market statistic chart with approximate sub-second accuracy. Obviously this will be better with genuine millisecond values - but I will have some work to do on this code when your millisecond-accurate timestamps go live. So it will be good to have some advance warning when this is coming! Question: will you be rolling out millisecond-accurate timestamps on the Sierra market statistics at the same time? Merlin |
