Same issue for me. I trade with two brokers on two separate machines and run SC on a third. Both brokers are in sync and SC real-time data feed is running behind. Actually, well behind.

In response to post #3 and #4, based upon what we see at the moment, there is a maximum outgoing buffer size in both cases of about 35K which was queued to be sent. For user User94215 we see you are tracking one symbol, so 35K would seem high but not necessarily.

Tell us what symbol you notice is delayed and how you are coming to this conclusion and how much of a delay there is. We only need to know about just one symbol. Do not overwhelm us with information.

For the record both of you are using the US equities data feed which we obtain from Barchart. We did a quick look at SPY and do not notice any delay of more than what would seem like a second at times but maybe you are noticing a problem at other times.

We have no reports of any problems with the futures data but that is a different data feed altogether.

We are waiting on Barchart to be able to move over to a new data feed of theirs for the US equities. So that may resolve the issue assuming that is where the problem is.

No and if the problem comes and goes we will might suspect that the issue is on the Barchart side. Or it could be an issue on your Internet connection side if you are tracking a lot of symbols. You might want to try low bandwidth mode:
Sierra Chart Exchange Data Feed: Low Bandwidth Option

One test we want you to do is through a Quote Board or a chart, add a symbol for the same symbol using the equivalent BATS exchange symbol. For example use SPY.BZ and see if at the time you notice a delay with that. BATS is driven through the Barchart Open Feed which is their newer feed.

The NYSE and NASDAQ runs through their older feed which we been meaning to update for some time now but just waiting on them to get some critical improvements done with that first.
