Introduction
The Arbitreads FIX Toolkit is a recently launched and not fully comprehensive implementation of the (F)inancial (I)nformation E(x)change protocol. While the API is open for all users, it is only useful for very specific requests that Arbitreads chose to implement (at time of writing, April 2026). For example, if you attempt to subscribe to Market Data you will get error messages like 'Requested operation is not allowed in DropCopy sessions.' or 'Requested operation is not allowed in order entry sessions.' It is possible to send new order messages / cancel order messages and to query the status of limit orders awaiting execution.
