ATAS Classic Platform Versions
Stable
The Stable version is the primary production release recommended for everyday use.
It is published several times a year and undergoes extensive testing by both the ATAS QA team and the ATAS community before release.
This version may not include the newest features available in later releases.
Latest
The Latest version is a release candidate that becomes available before the next Stable release.
It contains new functionality and bug fixes that have already passed beta testing and are undergoing final validation.
Beta
The Beta version contains the newest features and improvements currently under active testing.
Because development is ongoing, this version may contain bugs or temporary limitations.
Server Selection
The platform can connect to the following servers:
- F2
- E2
- T2
- R2
- Auto
When Auto is selected, the platform automatically connects to one of the available servers.
The selected server does not affect platform functionality because all servers provide identical services.
The servers host the following demo services:
- ATAS Sim
- Crypto Sim
- Crypto Data market data connection
ATAS does not provide real-time exchange market data by default. To receive live market data, connect a supported broker or market data provider.
