Apex Trader Funding Rithmic Setup Guide (2026): NinjaTrader, Sierra Chart, ATAS & More

Rithmic is not a trading platform. That distinction is important and frequently misunderstood. When Apex Trader Funding lists Rithmic as a "platform," what they mean is that Rithmic provides the data connection and order-routing infrastructure. The interface you actually trade inside — the charts, the DOM ladder, the order entry buttons — comes from a front-end application like NinjaTrader, Sierra Chart, ATAS, Quantower, Jigsaw, or Bookmap.

Choosing Rithmic at Apex account purchase unlocks access to all of those front-ends. Choosing Tradovate locks you into Tradovate's own data connection. The choice is permanent per account.

For a complete overview of all three Apex platform options (Rithmic, Tradovate, WealthCharts) and how to decide between them, see the Apex platform compatibility guide.

What Rithmic actually is and why Apex uses it

Rithmic is an independent market data and order routing provider used by prop firms and professional futures traders. Its infrastructure connects directly to CME Group's matching engine, which means low-latency data delivery. For US-based traders connecting to the Chicago server, round-trip latency is typically well under 10ms.

Apex uses Rithmic because it gives serious trading software — NinjaTrader, Sierra Chart, ATAS — a reliable, professional-grade data feed. Tradovate and WealthCharts have their own proprietary data connections. Only the Rithmic path opens the door to third-party platform ecosystems.

One technical point worth understanding: your Apex dashboard credentials and your Rithmic credentials are completely separate systems. Your Rithmic username and password are issued specifically for each funded account. They are not your Apex login. This is the source of roughly half of all first-time connection failures.

How to get your Rithmic credentials from Apex

Before opening NinjaTrader or any other front-end, retrieve your Rithmic credentials from the Apex member area. The location is non-obvious to new users.

Step by step:

1. Log into your Apex Trader Funding dashboard at apextraderfunding.com
2. Click "Accounts" in the navigation
3. Click the specific account you want to connect (if you have multiple accounts, each has its own credentials)
4. Click "Get Credentials" (the label may read "Account Credentials" depending on dashboard version)
5. Select "Rithmic" as the connection type
6. Your Rithmic username and password appear — copy both exactly

Do not attempt a platform connection until you have done the following: check your password for special characters (!, @, #, $, %, ^, &, *). If any are present, reset the password to letters and numbers only before proceeding. This takes 30 seconds and prevents the most common failure mode by far.

NinjaTrader 8 setup with Apex Rithmic

NinjaTrader 8 is the most widely used front-end for Rithmic on Apex. The setup involves several steps but is straightforward once you know the correct sequence.

Open NinjaTrader 8 and navigate to Connections. In the Control Center, click "Connections" in the top menu, then "Configure."

Add a new Rithmic connection. Click "Add" at the bottom of the Connections window. A provider list appears. Find "Rithmic" and double-click it.

Enter your credentials. Fill in:

• Name: a label you will recognize (e.g., "Apex 50K EOD")
• User: your Rithmic username from the Apex dashboard
• Password: your Rithmic password
• System: scroll and select "Apex Trader Funding" — do NOT select the generic Rithmic option
• Server: Chicago (standard for US trading)

Connect. Click OK to save, then right-click the connection and select "Connect."

Wait for data to load. NinjaTrader populates market data after connection, which takes 30 to 90 seconds. Do not place orders until the Market Analyzer shows live quotes for your instruments.

Add instruments using correct symbol format. The format is INSTRUMENT SPACE MONTH-YEAR: NQ 06-26, ES 06-26, CL 06-26. Always use the current front-month contract. NinjaTrader does not auto-roll symbols at quarterly expiration — you update them manually.

For multiple Apex accounts, add a separate connection profile per account, each using that account's distinct Rithmic credentials.

Sierra Chart setup with Apex Rithmic

Sierra Chart navigates differently from NinjaTrader. The connection settings live under File, not a dedicated Connections menu.

1. Open Sierra Chart
2. Click "File" in the top menu, then "Data/Trade Service Settings"
3. In the "Data/Trade Service" dropdown, select "Rithmic Trading"
4. Enter your Apex Rithmic username in the Username field
5. Enter your password in the Password field
6. Confirm the server is set to the Apex Chicago Rithmic server
7. Click OK
8. Connect via File > Connect to Data Feed

Sierra Chart's interface looks dated but the underlying capability is strong. The platform is the go-to choice for traders who need tick-by-tick data storage, historical replay, and ACSIL (C++ based) custom scripting. If you are running systematic strategies that require complete tick data archives, Sierra Chart is the strongest option in the Rithmic ecosystem.

Quantower setup with Apex Rithmic

Quantower is the easiest Rithmic setup of the major front-ends. The interface is cleaner and more modern than NinjaTrader or Sierra Chart.

1. Open Quantower
2. Click "Connections" in the top menu bar
3. Find "Rithmic" in the connection list and select it
4. Enter your Apex Rithmic username and password
5. Under "Server System," select "Apex Trader Funding"
6. Click Connect

Quantower's strength is built-in Volume Profile and cluster charts without requiring third-party add-ons. The DOM ladder is well-regarded for order flow trading. Setup time is typically under three minutes once credentials are in hand.

ATAS, Jigsaw, and Bookmap with Apex Rithmic

ATAS, Jigsaw Trader, and Bookmap all connect to Rithmic using the same core process: enter Apex Rithmic credentials, select "Apex Trader Funding" as the server system, connect.

Each has its niche:

• ATAS specializes in order flow analysis, footprint charts, and cluster charts. If footprint trading is your primary method, ATAS is the deepest tool in the Rithmic ecosystem for that work.
• Jigsaw Trader focuses on DOM (depth of market) analysis. Its Ordermap and reconstructed tape tools are among the most advanced available for reading order book dynamics.
• Bookmap visualizes the limit order book as a heatmap over time. Useful for liquidity analysis and understanding where large orders are stacked.

All three require the same credential retrieval and server selection steps described above. All three are locked to accounts where you selected Rithmic at purchase.

Comparing Rithmic front-ends for Apex

Platform choice is locked at Apex account purchase. If you buy a Rithmic account, you choose your front-end from this list for the lifetime of that account.

The most common Rithmic connection errors and fixes

The single fix that resolves the majority of first-time failures: reset the Rithmic password to alphanumeric characters before your first connection attempt. Do not skip this.

The April 17, 2026 Rithmic incident

On April 17, 2026, Rithmic experienced a data issue that temporarily affected PnL and daily drawdown limit (DLL) readings for Apex accounts. Apex issued an official status update confirming the issue and its same-day resolution.

What traders reported: balance and DLL figures appeared incorrect or frozen during the incident window. Trades themselves were not blocked, but some traders were uncertain whether they were approaching their drawdown limit.

What this means for Rithmic's reliability overall: Rithmic's track record is strong. Isolated incidents like April 17 are worth knowing about because DLL accuracy matters on a prop account, but a single same-day-resolved data display issue does not change the baseline assessment of Rithmic as professional-grade infrastructure. For context, Apex's other platforms have had their own separate connectivity issues over the same multi-year period.

The Apex 4.0 six-weeks-in recap covers the broader operational picture post-March 2026 launch, including the metals halt and payout processor change.

What market data is included with Apex Rithmic

Your Apex evaluation fee includes full CME Level 1 and Level 2 (DOM) data through Rithmic. No separate data subscription is required.

Covered instruments include: NQ, ES, YM, RTY (equity index futures), CL (crude oil), ZB, ZN (US Treasury futures), 6E, 6J, 6A (currency futures), and other CME-listed contracts.

One instrument class to note: as of March 14, 2026, Apex suspended all metals trading. GC (gold), SI (silver), MGC (micro gold), QI and QO (E-mini Silver and Gold), HG (copper), PL (platinum), and PA (palladium) are all halted. No return date has been given. This is an Apex-level rule, not a Rithmic or CME limitation.

For Performance Accounts, confirm with Apex support whether the same CME data package applies. In most cases it does, but verification before trading live capital is straightforward through the Apex help center at apextraderfunding.com/help-center/.

Rithmic vs. Tradovate on Apex: the essential difference

Tradovate is Paul's primary on Apex, having traded multiple $50K accounts over 2-plus years via Tradovate's browser-based interface. Rithmic powers a different set of use cases.

The practical split:

Choose Rithmic if you already use NinjaTrader, Sierra Chart, ATAS, or Jigsaw and want to keep your existing setup, indicators, and strategies. The Rithmic connection preserves your entire toolchain.

Choose Tradovate if you prefer a browser-based platform that works on any computer without software installation, or if you want to integrate with TradingView's charting on top of your funded account. More on that in the Apex Tradovate setup guide.

Choose WealthCharts if you want Apex's dedicated charting integration. It is the smallest user base of the three options, but some traders prefer it for the Apex-native experience. See the Apex WealthCharts setup guide.

The full comparison of all three with decision criteria is in the Apex platforms pillar.

Accounts, rules, and what affects your Rithmic setup

A few account-level facts that affect how you operate through Rithmic:

Contract limits. Your maximum contracts differ between eval and PA. A $50K account allows 6 contracts in eval, 4 in PA. A $100K allows 8 in eval, 6 in PA. Additionally, there is a PA half-contract phase: until your EOD balance exceeds the drawdown threshold plus $100, you are restricted to half your maximum PA contracts. Full contracts unlock the next session after clearing that threshold. See the Apex contract limits article for the full table.

EOD position closing. All positions must be closed by 4:59 PM ET. No overnight holds. This applies regardless of which front-end or connection you are using.

PA activation fee. Passing your Apex eval triggers a separate one-time activation fee: $99 for an EOD account, $79 for an Intraday account. This must be paid within 7 calendar days. Promo codes do not discount the activation fee. More detail in the PA activation fee guide.

Copy trading across accounts. You can copy trades from one of your Apex accounts to others using a tool like TradeDupe. Each account needs its own Rithmic connection with its own credentials. Each account must independently meet the 50% consistency rule in PA. See the Apex copy trading rules and the multi-account strategy guide for how this works in practice.

The bottom line

Rithmic is the data feed and order-routing backbone that connects professional trading platforms to your Apex Trader Funding account. The setup process takes under 15 minutes if you follow the correct steps: get the right credentials per account from the Apex dashboard, reset the password to alphanumeric only before connecting, select "Apex Trader Funding" as the server system rather than the generic Rithmic option, and wait for data to load before placing any orders.

The front-end you choose, NinjaTrader, Sierra Chart, Quantower, ATAS, Jigsaw, or Bookmap, determines your actual trading experience. NinjaTrader covers most needs. Sierra Chart is the specialist pick for algo traders. Quantower is the fastest to set up. ATAS and Jigsaw serve specific order flow disciplines.

Platform choice is locked at account purchase. If you want Tradovate or WealthCharts instead, those require a separate account. Start your evaluation at apextraderfunding.com.

Frequently Asked Questions

What is Rithmic in the context of Apex Trader Funding?

Rithmic is a professional-grade futures data feed and order-routing infrastructure. It is not a trading platform you see or click inside. Platforms like NinjaTrader, Sierra Chart, ATAS, Quantower, Jigsaw, and Bookmap all connect to Rithmic to receive live CME market data and send orders. When you trade Apex through any of those front-ends, Rithmic is the underlying connection layer.

How do you get your Rithmic credentials for Apex Trader Funding?

Log into the Apex dashboard, go to Accounts, click the specific account you want to connect, then select 'Get Credentials' and choose Rithmic. Each Apex account generates its own separate username and password. You cannot reuse the same Rithmic credentials across multiple Apex accounts, get credentials individually for each one.

Which server should you select when connecting Rithmic to Apex?

Select 'Apex Trader Funding' as the system or server in your platform's Rithmic connection settings, not the generic 'Rithmic' server. Using the wrong server is a common cause of stale data, connection errors, and order routing failures even when credentials are correct.

Why does my Rithmic login fail in NinjaTrader or Sierra Chart?

The most common cause is a Rithmic password containing special characters (!, @, #, $, %, ^, &). Rithmic's authentication can reject these silently or with a generic error. Fix: log into the Apex dashboard, reset your Rithmic password using letters and numbers only, then update your platform connection with the new password.

Is Rithmic included free with Apex Trader Funding?

Yes. Your Apex evaluation fee includes full CME Level 1 and Level 2 (DOM) data through Rithmic at no extra cost. You do not need to purchase a separate Rithmic data subscription. Confirm the same applies to your Performance Account, as data arrangements can occasionally differ from eval accounts.

What platforms work with Rithmic on Apex Trader Funding?

As of April 2026, the Rithmic-compatible front-ends for Apex are: NinjaTrader 8, Sierra Chart, Quantower, ATAS, Jigsaw Trader, and Bookmap. Tradovate is not on this list, Tradovate uses its own separate data connection and is chosen at account purchase.

Can you use Rithmic across multiple Apex accounts at the same time?

Yes. Each Apex account produces its own Rithmic credentials, and you add separate connection profiles in your platform. In NinjaTrader, for example, you configure a distinct connection for each account using that account's credentials. Each connection operates independently.

What happened during the Apex Rithmic incident on April 17, 2026?

On April 17, 2026, Rithmic experienced a brief data issue affecting PnL and daily drawdown limit displays for Apex accounts. Apex issued an official status update confirming the issue and its same-day resolution. Trades were not stopped, but affected traders reported temporary discrepancies in balance readings during the incident window.

Can you switch from Rithmic to Tradovate after opening an Apex account?

No. Platform choice on Apex is locked at account purchase. If you buy a Rithmic-based account, you trade through Rithmic-compatible front-ends for that account's lifetime. To use Tradovate, you would need to purchase a new account selecting Tradovate at checkout.

What symbol format does Rithmic use in NinjaTrader?

Rithmic uses the format INSTRUMENT SPACE MONTH-YEAR. Examples: NQ 06-26 for June 2026 Nasdaq futures, ES 06-26 for June 2026 S&P 500 futures. Always use the current front-month contract and update manually at each quarterly rollover, NinjaTrader does not auto-roll symbols.

Is NinjaTrader the best front-end for Rithmic on Apex?

NinjaTrader 8 is the most-used and most feature-rich option. It has the largest third-party indicator library, ATM strategy automation, and the SuperDOM order entry ladder. Quantower is a strong alternative for traders who want built-in Volume Profile tools and a modern interface. Sierra Chart suits systematic traders who need tick-by-tick data storage and custom scripting. The right choice depends on your trading style.

Does Rithmic support metals trading on Apex Trader Funding?

Rithmic itself supports metals trading, but Apex Trader Funding suspended all metals instruments on March 14, 2026, including GC, SI, MGC, QI, QO, HG, PL, and PA. This is an Apex rule, not a Rithmic limitation. No return date has been announced as of April 2026.
