"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum

"I had always used ******* but for the past 2 weeks have been trying DTN IQFeed. Customer support has been extraordinary. They call just to make sure your problem hasn't recurred." - Comment from Public Forum

"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon

"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

"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom

"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

Author	Topic: New User: VB Market Summary Socket (2 messages, Page 1 of 1)

I just built the API in VB, and started up the Market Summary Socket. When I tried to Request End of Day, I get a response of "No file available". I am using: Request: EDS,1,1,20200720,1. Any idea what is wrong? Also, is there a timeline of when the market summaries are available each day (except 5MS of course)? Thanks!

If I send the command SLM to the API, you can see the distinction: SLM 1,NGM,Nasdaq Global Market,5,NASDAQ, 2,NCM,National Capital Market,5,NASDAQ, 3,OTC,Nasdaq other OTC,5,NASDAQ, 4,OTCBB,Nasdaq OTC Bulletin Board,5,NASDAQ, 5,NASDAQ,Nasdaq,5,NASDAQ, NGM is exchange ID #1, but it belongs to exchange group #5 (it is part of NASDAQ). EDS accepts the latter. There is no group #1, which is why your EDS,1,1 returns "no file available." EDS doesn't use the exhange ID (the first number), it uses the group ID (second from the last). NGM belongs to exchange group ID #5, NASDAQ. So if you want that exchange, you would send EDS,1,5,20200724. Please note this will include all the NASDAQ exchanges, not just NGM. EDS files are compiled promptly after market close. I don't have an exact schedule of how long it takes, but a few minutes should be enough to wait. Let me know if this does not answer your questions! Sincerely, Gary Stephen DTN IQFeed API Support
