"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
"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

New IQFeed Forum » Minute Aggregated Snapshot? Oct 31, 2020 11:20 AM (Total replies: 1)

I'd like a minute aggregated snapshot of the same range of symbols (about 9000) as are provided by IEX's daily summaries:

Does IQFeed offer this?

If so, how much does it cost for:

  • 15 minute delayed snapshot?
  • current snapshot?


IQFeed Developer Support » Detecting Reverse Splits In Minute Aggregated Stream Nov 26, 2019 04:21 PM (Total replies: 4)

Let me explain the use case so you can properly prioritize this data feature (which is available in its entirety at https://www.splithistory.com/):

While backtesting an AlgoTerminal trading strategy, a market buy order is accompanied with a limit order. At the session close (end of day/EOD), the limit order is not reached and no bar update comes in at the end of day to permit the algorithm to sell the position at market. An overnight reverse X:1 split occurs but this is currently undetected by AlgoTerminal so it doesn't adjust the position (#shares/X and limit price*X). Upon resumption of trading the next day, the price is X*closing price > limit price. The limit condition met, AlgoTerminal sells #shares at price*X. Backtesting incorrectly reports a highly successful trading strategy.

If the backtesting stream included split multiples as well as prices, AlgoTerminal could do the adjustments necessary to produce valid backtesting reports.

Is it then true, as seems to be the implication, that minute aggregated pricing cannot with certitude be relied upon for backtesting prior to the first of the 2 split dates provided in the Fundamental data fields?

How can one detect when a symbol's price increase is due to a reverse split?

I've recently been bit by a backtest of an algorithmic trade with a ridiculously high yield that, when I tracked it down, was due to a reverse split causing an apparent increase in the stock's price.
