Full order book feed is nice but realistically, there very little benefit in paying for it unless you have the infrastructure to play low latency games. The feed itself is fairly affordable, especially if you concentrate on a single-listed product (for example, CFE full book feed is 3500 a month and touch-only is 1500). However, low latency setup that can take advantage of the alpha coming from the atomic order book updates is probably gonna run you a few hundred grand at least (especially if you include developers into that cost). Most large funds that are not involved in market making do not bother with the direct feeds and instead pay for something like RT or Bloomberg.I believe those paying top dollar for direct market feeds get some extra goodies.
That sounds about right if one wants to compete in the top tier, though from what I know about his business he is active across multiple venues which adds a lot of costs. You can get away with much less if you concentrate on very specific products/strategies."My costs for trading infrastructure, hosting, lines, software, feeds is $120,000/month. Everything seems to be getting more expensive lately." - garachen (from future.io forum circa 2013)
Anyway, I was actually wondering if he's talking about non-latency sensitive stuff like venue access.
