Connecting Rithmic

Which system to choose, and why the gateway matters.

Rithmic asks for two things beyond your login: which system your account lives on, and which gateway to reach it through. The system is the same name you pick on R|Trader Pro's login screen. Tradeus shows Rithmic's own list of systems: click the field and pick yours, or type the first letters to find it.

If the firm you picked under Prop firm issues Rithmic logins, the system box opens already searching for it, by a word from the firm's name such as Apex; a name you typed under Other firm… is searched as you typed it. A firm whose list has no Rithmic, reached through Show all brokers, leaves the box empty. Either way the search narrows the list; it does not choose for you. Open it and pick your system, because the exact name is Rithmic's, and Connect Rithmic account stays greyed out until a system is picked. The connection is then filed under that firm — see Connect a prop firm account.

A firm's own system
Many firms run a Rithmic system of their own, named after the firm, and Rithmic lists it. Search for its name. If it is missing, type the name exactly as R|Trader Pro's login screen shows it: Tradeus uses what is in the box, and Rithmic decides at login.
If Rithmic answers "permission denied"
Rithmic gives this one answer for several reasons, so check them in order: your username, password and system are exactly what you enter on R|Trader Pro's login screen; the same username is not signed in anywhere else right now; and API access is switched on for your Rithmic user. If all three are fine, Rithmic may not have enabled Tradeus on that system yet. Write to support and we take it up with Rithmic.

The Gateway list is 13 regional entry points — Chicago, Frankfurt, New York, Sydney and so on. Not every gateway carries every system: Core (Chicago) lists the most, and the system list follows the gateway you pick. Core (Chicago) is the default; change it only if you have been told to.

A Rithmic 01 account trades like any other
There is no read-only stage for a live account. Whether orders reach Rithmic is one switch on the server, the same for Rithmic 01 as for Paper Trading. So once a live account follows a strategy or a copy group, it trades real money. Test on Paper Trading first.
