"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken

I downloaded minute candles for PFPT for 3/9/2016 , and I see some candles are missing, such as:
13:02
14:23
14:33

Maybe some other minute candles are missing....

Please explain

If the stock didn't trade during those minutes, there won't be a bar.

Is there any possibility to get these 'missing' candles filled (with previous values) directly from the feed?

Or do i have to manipulate the data afterwards in order to have all minute values filled?

Good morning,

You would need to manipulate the data to suit you if you would like to see bars during these lulls in volume.

When retrieving historical data with 'Interval TimeFrame' (1 sec interval), i also get missing values. (Different seconds do not appear on the feed). You said this may be because there were no trades on that certain period, but, with Interval TimeFrame Requets, I am not getting trade values, but close values.

So it is not supposed that it has always to be a Open/High/Low/Close value for every interval requested? If there was not a single trade, this values would just be flat, but it seems that im not able to get a complete feed with second intervals.

Here you can se, that for example, i do not get 10:00:03 or 10:00:04 values for QHO# 'Interval TimeFrame' (1 sec interval) requesting:

[0] Close 1.4571 double
Date {12/07/2016 10:00:01}

[1] Close 1.4571 double
Date {12/07/2016 10:00:02}

[2] Close 1.4568 double
Date {12/07/2016 10:00:05}

Is it possible to do something with that?

Jose

Good evening,

We do not create any data points or bars for times where no data exists. So this would be the expected behavior for us.
