Technology and Connectivity

​The TASE as an Advanced Technological Organization

The Tel Aviv Stock Exchange is a central meeting point between companies raising capital and the investing public.
Trading on the TASE is currently completely automated, and the computer systems, which are amongst the most advanced and sophisticated in the world, enable continuous, safe and efficient trading in securities.
The large increase in trading and clearing volumes in recent years has required the TASE to be capable of meeting unprecedented loads. Thus, the trading servers, the central computer, the communications networks and the various backup systems were upgraded in the TASE building as well as in the backup site.
The online trading method requires ongoing development and maintenance of the computer systems, and today more than half of the TASE employees are computer and infrastructure personnel, responsible for the establishment and maintenance of computer systems.

Order Entry Network and Protocol

The TASE's trading network is intended for use by TASE members only, and is used for trading and for receiving real-time market data.
TASE provides its members with an interface for sending new orders and obtaining order approvals and their execution accordingly. The interface is a proprietary protocol of the TASE over TCP, called CTCI. The protocol includes:
  • New (buy / sell) orders
  • Order updates and cancellations
  • Order confirmations
  • Trade confirmations
  • Security / market status messages
TASE members that wish to connect to TASE can develop their own interfaces to TASE or, alternatively, use the services of a third party - Independent Software Vendor (ISV).

These software vendors have developed TASE interfacing software and have tested it with the TASE.  Some also provide connectivity infrastructure to TASE's (e.g. FIS).

Following is a list of Independent Software Vendors:
  • E&A Financial Software (TradeOne)
  • FIS Global Trading
  • FMR Computers and Software Ltd.
