How to Connect NinjaTrader 8 to Apex Trader Funding (2025 Step-by-Step)

Setting up NinjaTrader 8 with your Apex Trader Funding evaluation account is straightforward once you understand the connection architecture. Apex uses Rithmic as its data feed and order routing provider — NinjaTrader 8 has native Rithmic support. This guide covers every step from receiving your Apex credentials to running your first bot on a live evaluation account.

What You'll Need Before Starting

• NinjaTrader 8 installed — Download free from ninjatrader.com. The free version supports live trading; you don't need a paid license to run automated strategies on Apex.
• Apex Trader Funding account — You'll receive credentials via email after purchasing an evaluation. Look for your Rithmic username and password in the welcome email.
• Rithmic credentials — These are separate from your Apex login. Your Rithmic username and password are provided when your Apex evaluation is activated (usually within minutes of purchase).

Note: Apex uses the Rithmic Paper Trading server during the evaluation phase — despite being called "paper trading" internally, this is your live evaluation with real P&L tracking. Don't confuse this with the NinjaTrader simulated account.

Step 1: Open NinjaTrader and Navigate to Connections

Launch NinjaTrader 8. In the Control Center (the main NT8 window), click Connections in the top menu bar, then select Configure.

The Connections window shows all available broker and data feed connections. You'll see a list on the left including Interactive Brokers, TD Ameritrade, Rithmic, and others.

Step 2: Select Rithmic and Create a New Connection

In the left panel, click Rithmic. On the right side, you'll see connection configuration options.

Click Add to create a new Rithmic connection profile. Give it a descriptive name like "Apex Evaluation" so you can identify it if you later add a second account.

Fill in the fields:

• User Name: Your Rithmic username (from the Apex welcome email)
• Password: Your Rithmic password
• Server: Select Rithmic Paper Trading for Apex evaluations. This is correct — Apex evaluations run on the Rithmic Paper Trading server despite tracking real performance.
• Data Feed: Rithmic
• Order Routing: Rithmic

Click OK to save the connection profile.

Step 3: Connect to Rithmic

Back in the Control Center, click Connections → select your new "Apex Evaluation" connection → click Connect.

NinjaTrader will attempt to authenticate with Rithmic. A successful connection shows a green dot next to the connection name in the lower status bar. If the connection fails, double-check:

• Username and password match exactly (case-sensitive)
• You selected "Rithmic Paper Trading" not "Rithmic Live"
• Your Apex account has been activated (can take up to 30 minutes after purchase)
• No firewall or VPN is blocking the Rithmic connection

Step 4: Verify Your Account Appears Correctly

Once connected, open the Accounts window in NinjaTrader (Control Center → Accounts). You should see your Apex evaluation account listed with:

• Your starting account balance (e.g., $50,000 for a $50K evaluation)
• Current cash value and open P&L
• Account name matching your Apex account ID

If the balance shows $0 or the account doesn't appear, disconnect and reconnect. If the problem persists, contact Apex support — your Rithmic account may not be fully activated yet.

Step 5: Configure the Correct Instrument

Open a new chart in NinjaTrader. Right-click → Instrument → search for ES (E-mini S&P 500) or NQ (E-mini Nasdaq 100).

Important: Make sure the chart is using the Rithmic data connection, not the NinjaTrader Continuum (default demo) feed. Look at the chart header — it should show "Rithmic" as the data provider.

If you're trading ES, use the front-month continuous contract (ES 03-26 for March expiry, for example). Apex evaluations trade the front-month contract.

Step 6: Load Your Trading Strategy

If you have YMI bot templates installed (available with Pro Tier membership), load the strategy onto your chart:

1. Right-click the chart → Strategies → select your bot (Marty, KPL, or a specific template)
2. In the strategy properties, set Account to your Apex evaluation account (not the simulated account)
3. Verify Order Routing is set to "Rithmic" not "Simulated"
4. Set your position sizing and daily loss limit according to the Apex rules for your account size
5. Click Enable Strategy

Run the strategy for at least one session with small size (1 micro or 1 mini contract) to verify fills are routing correctly to your Apex account before running full-size positions.

Step 7: Verify Live Order Routing

Place a single small test order manually to confirm the connection is routing to Apex and not NinjaTrader's internal simulator:

• Open the Orders window in NT8
• Place a limit order 10+ points away from current price (so it won't fill immediately)
• Check your Apex dashboard — the order should appear in your Apex account
• Cancel the order from NT8 and verify it cancels in Apex

If orders appear in NT8's Order window but not in your Apex dashboard, you're routing to the NT8 simulator, not Apex. Re-check the strategy account assignment in Step 6.

Running on a VPS for 24/7 Bot Operation

For reliable automated trading, run your NT8 bots on a Virtual Private Server (VPS) rather than your local machine. A VPS keeps bots running 24/7 without power outages, internet drops, or Windows updates interrupting the connection. Use a Chicago-based VPS for low latency to the CME exchange — target under 5ms round-trip to the Rithmic servers.

The connection setup process is identical on a VPS — install NT8, configure the Rithmic connection with your Apex credentials, load your strategy templates, and enable. Then close the Remote Desktop session. The bots run continuously until you reconnect to check results.

Apex-Specific Risk Management Configuration

Before going live, configure these mandatory risk parameters for a $50K Apex evaluation:

• Daily Loss Limit: Set NinjaTrader's account-level daily loss limit to $400–$600 (20–25% of the $2,500 trailing drawdown threshold)
• Profit Target Gate: Set a daily profit target walk-away at $300–$500 (10–15% of the $3,000 profit target)
• Consistency Rule: Configure the strategy's daily target so no single day exceeds 30% of cumulative profit — YMI's Steady Gains template handles this automatically
• Minimum Trading Days: Apex requires 7 minimum trading days. The Steady Gains template is calibrated to pass in 14–21 days, safely meeting this requirement

Troubleshooting Common Connection Issues

Problem: "Authentication failed" on connect
Solution: Double-check credentials in the Apex member portal. Rithmic passwords are case-sensitive. If recently changed, wait 5 minutes for propagation.

Problem: Connected but no market data
Solution: Ensure you're subscribing to CME data through Apex (included in evaluation). Check that charts are set to the Rithmic data feed, not Continuum.

Problem: Orders not appearing in Apex dashboard
Solution: Verify strategy Account setting is your Apex account, not "Sim101" or "Default." Right-click strategy → Properties → check Account field.

Problem: Disconnecting randomly during the session
Solution: Use a wired ethernet connection on a VPS rather than WiFi. Set NT8 to auto-reconnect: Tools → Options → Connection → enable "Auto-reconnect on disconnect."
