Our original space at ATVWhile ATV gave us a great start, we wanted a place we could call our own. So we began searching for a new location in late September, 2019. We wanted a modern, lof

Market data is a driving factor in today’s world of finance. We are so often used to associating it with the corporate world, we sometimes forget the useful and important role it can play in educating our world’s future generation of financial professionals.

We posted a couple months ago that free forex accounts were no longer available, and that current free accounts would be closing soon. Now that the new forex integrations are complete, we must begin paying license fees per user, per month. Which means we can no longer offer forex data freely to users.

We have added an additional cluster of Forex banking institutions. Due to adding this, and plans to add more, we have modified the schema of the forex ticks to include the exchange ID. This will be valuable when looking at the prices between forex banking institutions. The Forex schema will be updated April 17, 2018. Since this is a schema addition, and not editing/removing a key, we expect the impact to be low on client application logic. Thanks,

We have changed both channels to only broadcast updates on the tickers which have actually had trades in that timespan. Which means the average is ~1000 ticks/second instead of ~8000. This allows better throughput, and less processing messages of tickers that have not changed.

Over the past 2 weeks we have made several infrastructure changes and upgrades. The changes touched almost every part of the system, therefor you may have noticed breif latency spikes up to 200ms. However we tried to keep the upgrades completely transparent. The upgrades allow for us to add real-time data feeds more easily, with less latency and better message delivery guarantees. Which means better APIs and more data streams for you. Below are some details for the techies who are interested.
