Rithmic Trading Screens

R | Trader™

R | Trader™ is Rithmic’s front end trading and real-time risk management screen. With R | Trader™ you can view quotes, trades, market depth and option strikes in real-time. You can place, modify and cancel orders, and view order history, performance, positions and risk limits. R | Trader™ supports trailing stops, brackets, OCOs and group orders.

FCM and broker administrators use R | Trader™ to do all that traders can do on behalf of any of their users and accounts. Administrators can set risk limits, activate and deactivate users and accounts and record fills and cancels whose execution has been made outside of R | Trade Execution Platform™.

R | Trader Pro™

R | Trader Pro™ is R | Trader™ with charts and a real-time interface to and from Microsoft Office Excel. In addition to all the functionality of R | Trader™, with R | Trader Pro™ you can view about 100 studies and stream them in real-time into Microsoft Office Excel spreadsheets. With the power of Excel, you may develop your own indicators and, using Rithmic’s two way real-time interface, you may configure trades to be sent back into R | Trade Execution Platform™ through R | Trader Pro™, automatically or with the click of a button.


R | BASS™ is the ultimate scalping tool. R | BASS™ looks for the spread between a symbol’s best bid price and best ask price to widen by a set number of ticks and then inserts a new bid and a new offer at one tick better. You configure the spread and you can set the trade to begin and end at specified times. R | BASS™ is the ultimate Bid Ask Spread Scalper.

R | Criss Cross™

R | Criss Cross™ places an opposite order for a symbol at a specified profit target when it detects a fill. You choose the symbol and you specify the profit target. When R | Criss Cross™ detects a buy fill, it submits a sell order a few ticks above it. When it detects a sell fill, it submits a buy order a few ticks below it. You configure how many ticks. From receipt of the fill message to just after submission to the exchange R | Criss Cross™ generally takes less than 250 microseconds. For a market that is trading in a narrow range, nothing beats R | Criss Cross™.


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).
