Hi Legend
The Infinity AT datafeed is unfiltered and unbundled, so it is very fast and sends dozens of updates per second, therefore some computers and/or internet feeds cannot handle this. We added the Limiter so users who cannot handle this can "choke" down the amount of data coming through. Typically, this does not change the ticks (or trades) one sees, or even the best bid/ask prices, just the quantity updates on the Bids/Asks on the DOM. Unfortunately, Ares is having an issue unique to his computer and I have asked him to call me so I can diagnose it, but so far I have not heard form him. Obviously, if this was a common occurrence we would not have thousands of happy users on Infinity AT.
