Most prop traders spend hours researching challenge rules, profit splits, and max drawdown thresholds before picking a prop firm. Fewer spend five minutes thinking about what’s actually running underneath their funded account when they pull the trigger on an ES trade at 9:35am.
That’s where Rithmic comes in. And once you understand what it does, you’ll probably never ignore it again.
What Is Rithmic?
Rithmic, LLC is a trade execution infrastructure provider. Founded in 2006 and headquartered in Orangeburg, New York, they build the plumbing that sits between the exchange and the platform you’re staring at. They’re not your broker. They don’t hold your funded capital. They don’t set your profit targets or your trailing drawdown.
What they do is route your orders, deliver your market data, and enforce risk rules, all at the infrastructure level, independent of whichever platform you’re trading on.
Their tagline is “We Put Your Trades First™” and that’s actually a pretty accurate description of the architecture. The order goes from you to Rithmic to the exchange. No unnecessary hops, no extra intermediary layers introducing latency between your decision and the market.
If your prop firm runs on Rithmic, and a significant portion of active funding evaluators do, then this infrastructure is already underneath your account right now. Understanding how it works can directly change how you approach your evaluation.
The Three Things Rithmic Controls That Affect Your Trading
Rithmic’s platform runs on what they call the R | Trade Execution Platform™, built around three independent hubs that operate simultaneously.
Market Data Hub. This is where your price feed comes from. Rithmic pulls raw data directly from exchanges, normalizes it, and distributes it in real time. The key phrase here is un-throttled. Most data feeds apply some level of filtering or aggregation, particularly during volatile sessions when tick volume spikes. Rithmic’s stated position is that every tick, every order, every level gets delivered exactly as the exchange sends it, without filtering even during peak volatility. For prop traders this matters more than it might seem. When NQ is running 30 points in two minutes at the open, you want to know what’s actually in the order book, not a smoothed version of it.
The feed also includes Market-By-Order data, which goes deeper than standard market depth. Rather than showing you aggregated volume at each price level, MBO data shows individual orders sitting at each level. It’s the most granular view of market structure that exchange connectivity allows.
Historical data goes back to December 2011, with 40GB of tick data, bars, and aggregated data available per user per week.
Order Management Hub. Your orders get validated, risk-checked, and routed to exchange gateways here. Order routing latency is measured in microseconds, not milliseconds. For context, a millisecond is a thousand microseconds, and in futures markets, queue position at a given price level is everything when liquidity is thin. Rithmic also supports server-side order types including brackets, OCO orders, and trailing stops. Server-side matters because these order types live on Rithmic’s servers, not on your platform. If your internet drops mid-trade, those orders don’t evaporate.
Risk Management Hub. This is the piece most relevant to funded traders specifically, and it’s genuinely worth understanding.
Server-Side Risk: Why This Changes Things for Funded Accounts
Here’s a scenario traders run into more often than they admit. You’re on day 9 of your evaluation, you’re up on the week, and your internet connection drops at a bad moment. Or your platform freezes. Or you lose power.
With client-side risk systems, which live inside the trading platform itself, a disconnection can mean those risk rules go offline too. The position stays open. The loss keeps accumulating.
Rithmic’s risk enforcement runs at the infrastructure layer. It doesn’t live inside NinjaTrader or Quantower or ATAS or any other platform you connect through. It lives on Rithmic’s servers, operating independently of your connection state. If your platform crashes, the risk rules don’t crash with it. Auto-liquidation criteria fire regardless of whether you’re connected.
For funded traders, this is significant. The rules your prop firm configured, loss limits, trailing minimum balance, position limits, whatever their evaluation structure requires, are being enforced at a layer you can’t accidentally disable by closing an app or losing WiFi.
The system supports more than ten configurable auto-liquidation criteria, including trailing minimum account balance (the floor rises as your account grows, similar to how trailing drawdown works at most prop firms), loss limits, profit limits, end-of-day drawdown, and quantity limits on position size. These can run simultaneously. When any threshold is breached, liquidation fires server-side, immediately.
Accounts can also be set to one of three states, Active, Liquidate Only, or Admin Only, giving prop firm operators granular control over what’s permitted at any given moment.
The Platform Situation: What You Can Actually Trade On
This is where Rithmic gets genuinely impressive for a behind-the-scenes infrastructure player. Thirty-two trading platforms connect to Rithmic. The list covers basically every serious futures platform traders actually use.
NinjaTrader. ATAS. Quantower. Bookmap. Jigsaw Trader. Sierra Chart. MultiCharts. MotiveWave. OptimusFlow. Volfix. AgenaTrader. OverCharts. TigerTrade. TradeNavigator. And more.
Order flow traders, DOM scalpers, systematic algo traders, Elliott Wave analysts. There’s something for everyone here. Bookmap’s heatmap visualization runs on Rithmic data. ATAS’s footprint charts pull from the same un-throttled feed. Jigsaw’s tape reading tools get the full order flow. Rithmic’s own R | Trader Pro™ is available as a desktop platform on Windows, and there’s a web and mobile version for trading from a browser or on iOS and Android.
The connection works the same regardless of which platform you’re using. Your data, your execution, and your risk management run through the same Rithmic infrastructure whether you’re on NinjaTrader or Quantower or their own platform.
One thing worth knowing about running multiple platforms simultaneously: connecting a second application to the same Rithmic data feed will disconnect the first. If you want to run two platforms at the same time, you use Plugin Mode through R | Trader Pro™. Launch it first, click Allow Plugins before logging in, then connect your third-party platform through it and keep R | Trader Pro™ running in the background for the session.
Rithmic also offers connection guides for most of the major platforms, and their support team is reachable at support@rithmic.com for anything not covered in documentation.
Global Reach and Exchange Connectivity
Rithmic infrastructure is deployed across 13 global connection points: Aurora, Chicago, New York, Frankfurt, Dublin, Singapore, Tokyo, Sydney, Hong Kong, Mumbai, São Paulo, Cape Town, Seoul. This means wherever you trade from, there’s a Rithmic gateway positioned near a major exchange matching engine.
Exchange connectivity covers CME Group in full (CME, CBOT, NYMEX, COMEX, the full suite of equity index, interest rate, energy, metals, and agriculture futures), the Small Exchange (SMFE), Nasdaq for US equities top-of-book, and EUREX for European derivatives. The CME connection is what matters most for traders focused on ES, NQ, MES, MNQ, CL, GC, and the other contracts that dominate prop firm evaluation activity.
EUREX access is currently available only for customers of certain FCMs, specifically Dorman Trading, AMP Futures, Wedbush Securities, and The Trading Pit, with broader availability planned.
The Free Trial
Rithmic offers a 14-day free trial for new users through their Exchange Simulator. This is a paper trading environment that connects to live market data from CME Group and Nasdaq in real time, not a replay system or synthetic feed. Fills happen against a simulated matching engine, but the data you’re watching is the actual live market.
The trial supports all 32+ compatible platforms, includes R | Trader Pro™ immediately without additional setup, and allows API testing for developers building on the infrastructure. No credit card required to start.
After the trial, continuing access requires a paid subscription. Rithmic directs pricing questions to their sales team (sales@rithmic.com) and to your broker or funding evaluator relationship, since data subscription and routing fees are typically handled through that relationship rather than directly.
The demo login uses the email address from signup, and it’s case-sensitive. Use the same combination of upper and lower case letters used during registration.
Maintenance windows run daily from 5:20 to 5:45pm ET Monday through Friday. Weekend maintenance runs from Friday night through approximately noon ET on Sundays.
So Why Does This Matter to You as a Prop Trader?
Because the infrastructure underneath your evaluation account isn’t a background detail. It determines whether your data is filtered or complete, whether your server-side orders survive a connection drop, whether your risk rules stay active when your platform freezes, and which trading platform you’re actually allowed to use.
Traders who understand that Rithmic is running underneath their funded account can make better decisions, choosing platforms that connect to it, understanding why their DOM data looks different from other feeds they’ve tried, knowing what happens to their risk rules when things go sideways technically.
The firms in Rithmic’s partner network include Apex Trader Funding, Topstep, LeeLoo Trading, TradeDay, Earn2Trade, OneUp Trader, Elite Trader Funding, My Funded Futures, Take Profit Trader, UProfit, and dozens more. If your firm is on that list, you’re already on this infrastructure.
Traders at those firms who take the time to understand what’s underneath their account are better positioned to use it well.
