I get this product is for retail customers and that it's not designed to be the fastest thing in the world, but just how lagged can this feed get? I was running a test, where: Market was quoting me (penny offsets) .56 x .57, then the market temporarily became locked .57 x .57, and I let an order sit at .58, for a sell. I get filled at .58, IQ Feed is showing me .57 x .57 still. My code is now thinking it just got a free lunch, so it parks another order at .58, gets hit again. Since I'm getting too many "free lunches", a safety trigger kicks and the strategy turns off, and I'm able to verify that all is not well in Denmark. So I'm asking ET if other people see these temporary lags when the market pops up or down with IQ Feed, and the "true" maximum lag against the exchange that this feed can see, and whether I should buy access to a secondary feed as a cross-check against IQFeed. I see these back ups occasionally during the day, maybe 2-5 times.
