What’s the typical latency for datafeeds?

We define our latency SLA from when the data is created off the matching engine to when the data is available for consumption at our perimeter, not when it appears in the consumer’s system, as we can’t control the networking, connectivity, etc elements once the data leaves our perimeter. Our SLA is around 300 milliseconds for when the data is available for consumption. This can be optimized depending on many factors, so you may be able to achieve latency under 300 milliseconds.
