Rithmic API documentation, prices, ...?


Where can we get more details on how the R API is working, what is its costs, and some technical documentation ?
I would also like to know what would be the overhead in using a server in Chicago, and not directly in Aurora ?


It’s been 6 months, I like to raise sam028028’s question again, what is the cost/month of running the Rithmic data feed API with my own platform regardless of the brokerage fees (with say 100 contracts RT/month trading ES)?

The cost is 10 cents per side with a minimum of $100 per month (500 RT).
In the event that you don’t meet the minimum, the difference is charged to your account.

Thank you,


sorry if I reup an old thread, I’m software developer and I’d like to see the API documentation for C#
