aamar -Interested User- Posts: 7 Joined: Oct 8, 2021	Posted: Oct 8, 2021 05:36 AM Msg. 1 of 4 Hi, I am looking to stream 1 second data for several symbols. I am just testing so i can approach it correctly. I am using the sample provided in C# to stream EURUSD.FXCM 1 second. However, I expect to get a bar every second regardless of if there is any price change in that second or not but it seems to send quotes when price changes and gaps of 2-3 seconds before the next quote. I need to do a calculation based on the number of bars and if there are any missed bars, it will not be accurate. Is there any option to always stream the quotes per requested interval? regards Aamar File Attached: example.JPG (downloaded 611 times)

There isn't an option to force it to send "placeholder bars" or anything like that. This is just the way IQFeed data works. Sincerely, Gary Stephen DTN IQFeed Implementation Support Specialist
