Realtime or historical tick server AMI's |
| Message: |
Hi,
This relates to a post I made to an OpenTick forum.
Specifically I think it would be useful to provide an Amazon Machine Image that is a realtime or a historical tick server.
It seems to me you have the data and software already, and Amazon's EC2 and S3 web services have the remaining necessary components.
This would permit users to gain access that is not as expensive as a direct data feed, but _much_ cheaper, faster and more reliable access than current offerings.
I'd envision you distributing a software package that a user installs on their AIM that, once they log in, provides them with a realtime or historical tick server.
It would seem natural to adopt the OpenTick API specification since that is developed, documented and has a ready user base.
Realtime tick speed is an issue so it might be that you need to sample price ticks while aggregating volumes and counts, but these could be self configuirng (depending on the bandwidth available) or user configurable.
The benefits of this several:
- _much_ cheaper than dedicated connections, and could be just as reliable
- accessible to smaller (sophisticated) clients than those with dedicated IT departments
- much faster download speeds
- if the historical data is housed on Amazon's S3 then historical tick server traffic within the EC2 is not billed or billed at $0.01/GB (European-USA traffic is currenly treated differently by Amazon)
You may like to charge for the tick server software or support incidents(or sub-contract those), but really you make you money from trading, and this would definitely facilitate that. No?
Overall it seems this would represent a dramatic change in the accessibility of exchange data.
For the same reasons that retail outlets congregate, it would seem sensible for exchanges to agree to provide a consistent interface to their data, and the OpenTick API seems to be the natural starting point.
If you are not willing to provide such a service, perhaps you might consider facilitating OpenTick providing such functionality?
I appreciate there are several questions posed, and it might take time to prepare answers, but I, and I'm sure some others, would greatly appreciate you feedback on these questions.
Cheers
