There is an on-going project at its final stage related to co-location services.

There are 3 ways of order submission currently:

1. From Trading Floor through Trading Workstations.

2. From Member Locations through remote access called ExAPI.

3. From Member Locations in FIXAPI Protocol.

Borsa İstanbul does not support HFT yet.

Yes, there is a Programmers’ Manual for ExAPI and a Rules of Engagement Document for FIXAPI protocol.

A member can send up to 400 orders/second through FIXAPI protocol in equity markets.

Yes, a message throttling mechanism is applied to limit number of orders per second each member is authorized to send.

By Futures and Options Market API terminals, 15 orders can be submitted in one second. We are planning to launch Futures and Options Market FIX API at the beginning of April. Submitting an order by FIX API in one second will be many times more than by API terminals. The detailed information about this subject will be given as soon as possible.

It is not possible to give historical data, but when co-location service is given, this subject will be evaluated again.

These metrics are related with your lines. That is why it is not possible to give an exact number. However, you can measure the latency by sending a ping.

The studies about this subject are going on. We can not give an exact time, but it will be announced when ready.
