PropFirmConnectorMultiple logins.PropFirmConnector connects Rithmic prop firm and brokerage accounts that have no native connection in NinjaTrader, and runs several Rithmic logins at once in one NinjaTrader window. It runs on the trader’s PC or VPS, and they sign in with the Rithmic credentials they already have.
Your traders want the same thing.
If your traders say yes, you can offer NinjaTrader within hours. Your developers feed our API docs to their AI assistant, and it does most of the integration work.
Would you trade your Rithmic account with us in NinjaTrader?
They differ in who bills the trader and how you earn.
Your server activates each trader’s license, so they buy and download on your website. We bill your firm at discounted license pricing.
Choose it when you want traders to get NinjaTrader access the moment they check out on your website, whether you sell one license a month or hundreds. Every prop firm in our case study uses it.
License API guideYour server requests a single-use discount code for a trader. They buy their license from us, and we handle payment, licensing and renewals. Your firm is never invoiced.
Choose it when you want traders to get a discount and to see which codes were used, with no licensing or billing to handle.
Coupon API referenceShare your affiliate link and coupon. Your customers buy from us at a discount, and you earn a revenue share on each one.
Choose it when you want to give your customers a discount and earn on each referral, with nothing to build. The most popular option with NinjaTrader vendors and communities.

License API: your firm buys licenses from us at discounted license pricing and your server issues them. Traders buy and download on your website, and you set their price. Coupon API: you give the trader a single-use discount code and they buy their license from PropFirmConnector directly. We handle checkout, billing and renewals, your firm is never invoiced, and the API shows whether each code was redeemed.
Yes. The integration is what gives traders NinjaTrader access the moment they check out on your website, with no manual step, so build it at any volume, even one customer a month. It is three endpoints, with an OpenAPI spec and a Markdown reference you can hand to an AI coding assistant.
Yes. Our MCP server is an alternative to the API for AI agents. An administrator connects an AI app with their Vendor Admin sign-in and chooses what it can do. Your support staff and developers can then check, activate and change licenses, create discount codes and get download links by prompting. Each change applies immediately, like an API call, under the same pricing and license rules, and an owner can turn AI changes off at any time.
Yes, through the affiliate program, which needs no API. Your customers get a discount with your affiliate coupon, and you earn a revenue share on each one you refer. The License API and Coupon API pay no revenue share: the whole coupon discount goes to the trader, and with the License API you earn by charging traders more than we bill you.
No. With PropFirmConnector your traders connect the Rithmic logins they already have in NinjaTrader 8. You keep your existing Rithmic data feed, risk management system and account types, and we handle NinjaTrader connection support. Adding Tradovate accounts instead means a second data feed, a second risk system and an approval process with NinjaTrader that prop firms tell us takes 6 to 12 months and is not guaranteed.
No. Prop firms use it so traders can run the firm’s Rithmic accounts in NinjaTrader 8. NinjaTrader vendors (add-ons, indicators, trade copiers, VPS hosting) use it to offer their customers a discounted PropFirmConnector license.
Yes. They are separate permissions on one vendor account, so you can start with coupon codes and add the License API later. An existing coupon key keeps working.
Rithmic evaluation, funded and live brokerage accounts, including account types with no native NinjaTrader connection. Send us your website and account types and we will confirm your setup.
NinjaTrader 8 on Windows, the PropFirmConnector add-on with an active license, and valid Rithmic credentials from their firm or broker. The Vendor API does not create trading accounts, supply market data or replace NinjaTrader’s own requirements.
With the License API we match the email you send to their account and add a separate license slot from your firm. Licenses they already hold stay independent. If the email is new, we create an account.
License API: your firm collects customer payments and we invoice your firm monthly at your agreed license pricing. A monthly license is charged every 30 days while enabled; a lifetime license is charged once. Status checks, downloads and retries are free. Sponsored-access terms are agreed separately. Coupon API: your firm is never invoiced. The trader buys the license from PropFirmConnector directly.
Send us your website, Rithmic account types, preferred option and expected number of traders.
We agree on your offer and enabled API capabilities.
