Programmatic Trading Interfaces

R | API+™

R | API+™ is a collection of software libraries and interface definitions that developers and screen designers incorporate into their proprietary software to gain access to R | Trade Execution Platform™. R | API+™ provides its callers with a normalized view of market data and reference data and of order and execution reports across all supported exchanges. Timestamps are provided with the granularity set by their source: microseconds respecting market data receipt and order submission by R | Trade Execution Platform™ and milliseconds to nanoseconds as published by the exchanges.

Additionally, R | API+™ provides access to R | Trade Execution Platform’s™ symbol lookups and server side features: trailing stops, brackets and OCOs, custom time, tick, volume and price range bars.

R | Diamond API™

R | Diamond API™ is R | API+™ but with access to R | Trade Execution Platform’s™ ultra-low latency and high frequency trading capabilities.  R | Diamond API™ contains R | API+™ but also enables its caller to connect directly to Rithmic’s exchange facing gateways and to connect to Rithmic’s market data handlers.

A program that incorporates R | Diamond API™ (also referred to as a Diamond Program™) connects to R | Trade Execution Platform™ as any program does that incorporates R | API+™, but, subject to Rithmic’s exchange entitlements processing, it connects directly to Rithmic’s market data handlers instead of connecting to Rithmic’s ticker plant and it connects directly to Rithmic’s exchange facing gateways. As the Diamond Program™ gets market data from Rithmic’s market data handlers it evaluates that market data with an eye toward releasing orders. When a Diamond Program™ decides it is time to release an order to an exchange, it simply sends the order to one of Rithmic’s exchange facing gateways. Subject to Rithmic’s pre-trade risk parameters (set by the FCM), evaluated by the exchange facing gateway, the order is sent to the exchange.

Traders using Diamond Programs™ realize transit times (the time just before market data is read until the time just after an order is released to an exchange based upon that reading of market data) of less than 250 microseconds (actual times vary and are generally faster).
