SCDateTimeMS latest_tick = sc.LatestDateTimeForLastBar; SCDateTimeMS bar_ts = sc.BaseDateTimeIn[sc.ArraySize-1]; if (latest_tick - bar_ts >= MILLISECONDS * 500) { ..... } Assume the feed is MS timestamps. We want the "if" statement to evaluate to true when 500 MS have passed since the beginning of the last bar. Does that look correct? |

At this time Sierra Chart does not make millisecond time resolution available from the data feed. You really have to keep track of time within the study itself and use sc.UpdateAlways and have the study function called maybe every 100 ms.

I am confused seeing this post- Bid, Ask and Last driven chart. | Post: 88049 Does that post mean that SC does support MS timestamps if/when they come in on a feed? Or is it specific to importing from a text file? |

This is only specific when importing from a text file. Sierra Chart does not support milliseconds from the data feed at this time. Update: We checked, and this is actually not correct: Although if you use milliseconds in a DTC market data update trade message, then Sierra Chart will store the milliseconds as given.

Got it - so just to confirm a few things. 1. I can almost swear that SC did once support ms timestamps from the data feed - is that correct? 2. Are there any immediate plans to support this? |

1. Only mistakenly. Unless properly implemented it causes subtle issues with downloading of historical tick data and certain functions within the program. Actually you cannot use milliseconds in a DTC message. The millisecond portion is truncated off. 2. Not immediate. It is something that requires a lot of small changes and widespread code review to make sure it is implemented properly. Sierra Chart Support - Engineering Level Your definitive source for support.

Please take note that the need for this functionality has come up a couple of times on two none related projects in the last 3 months. In both context it was a surprise not to have it as other platforms are supporting this and it is "expected" that SC is a leading technology when it comes to data and accuracy if you understand what I mean. Obviously you have your view on things but thought to provide my 2 cents. |

What data feed is being used? If it is your own data feed through a DTC Server, then it is easy for us to support milliseconds from that data feed. Just let us know and we will put this out in the next release. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

In both instances mentioned above the data feed is DTN and do not involve DTC. Now that you mention it, it did come up also in context of DTC but in that case SC was the server and was connected to CQG. |
