What is the reason you use IQ Feed rather than the Sierra Chart Exchange Data Feed?

As you can see in this chart, there is no such error for this symbol from the Sierra Chart Exchange Data Feed:

In the last several months, we have spent a lot of time and money improving the stock data from the Sierra Chart Exchange Data Feed. At this time it works very well.

The only outstanding issue, is a slight discrepancy between our servers with CME data due to a small amount of packet loss and we are addressing that in the next 2-3 days. Although at the end of every day, we make the historical data on both servers is the same.
