Possible for no latency with tick database with new SQL Server 2014 in memory for HFT
I kind of question this myself but it could be possible to get to close to no latency. If you watch this demo, I kind of wonder if it is possible with low coding maintenance thanks to C# and .NET, This could be useful for potential HFT purposes but I could be wrong. But let me know what you think.
