Python Rithmic API Trading App

• This is a minimum viable product (MVP).
• It provides access to the following:

• You must provide your own trading strategy and execution logic. You can place it in the runstrategy() function in rithmictrading_app.py.
• The app is configured to place market orders only.
• The app is configured to execute the strategy placeholder every 5-minutes.

Prequisites

• You must have either a Rithmic Paper Trading or Rithmic Live account, NOT A TEST ACCOUNT.
• You must pass Rithmic's conformance testing.
• After passing conformance testing, Rithmic will send you the following:

A four-character prefix

Rithmic will send you a four-character prefix.

• In mdstream.py, pospnlstream.py, histbarsohlc.py, and placeorders.py, find the following variables:

Proto Files

In the library imports section of the Python files (mdstream.py, pospnlstream.py, histbarsohlc.py, and placeorders.py) you will see references to _pb2 files. You must get those from Rithmic and drop them in the protobuf directory.

SSL Cert File

The application files reference the rithmicsslcertauthparams file. You should have received that file from Rithmic. Drop your copy in the root directory.

URI

After you pass conformance testing, Rithmic will send you the URI to access its system. In the rithmictradingapp.py file, go to the line uri = 'CHANGE_ME' and assign the variable with the URI supplied by Rithmic.

Installation

Download the repo to your hard drive.

Start App

After downloading the repo, cd to pythonrithmictrading_app.

Run the following command:

python rithmictradingapp.py [username] [password] [exchange] [contract symbol] [contact qty] [FCM] [IB]

For example, if your Rithmic credentials are 00000000-DEMO/password123 and you want the trading app to monitor the Crude Oil market and to trade only one quantity of the December 2024 contract, through your IB (e.g., Ironbeam) and FCM (e.g., Ironbeam), then you would run the following command:

python rithmictradingapp.py 00000000-DEMO password123 NYMEX CLZ4 1 Ironbeam Ironbeam

After starting the trading app, you will see a series of INFO messages indicating that the app is receiving tick data, monitoring PnL and position data, and is executing the strategy placeholder every five minutes.

Stop App

To stop the app, issue a KeyboardInterrupt, Ctrl+C.

Live Trading

After thoroughly testing your trading strategy and execution logic, if you wish to trade live, do the following:

• In rithmictradingapp.py, find the variable system_name.
• Change its value from Rithmic Paper Trading to Rithmic 01.
