TradeSea Connection Guide to NinjaTrader 8

Firm website: tradesea.ai

It depends on who issued the Rithmic login. Accounts from TradeSea’s partner prop firms, such as Lucid, Tradeify, Alpha Funded or BluSky, use their firm’s System, which each firm’s guide lists. For Rithmic credentials issued on TradeSea’s own system, select tradesea for System in PropFirmConnector.

Your TradeSea Rithmic account and login

TradeSea (tradesea.ai) is a web and mobile trading platform built on Rithmic. Prop firms including Lucid Trading, Tradeify, Alpha Funded, BluSky, EdgeProp, FundYourEdge and Halcyon Trader Funding let traders use it with their Rithmic accounts.

Rithmic also runs a dedicated tradesea System, which PropFirmConnector lists. Use it only for credentials issued on that system; accounts from TradeSea’s partner firms keep their firm’s System in NinjaTrader 8.

Where to find your TradeSea Rithmic login

TradeSea itself signs in with Google, Apple or an emailed code, with no password; it connects to accounts with the Rithmic username and password your prop firm issues. Use those Rithmic credentials in PropFirmConnector, never your TradeSea sign-in.

How to connect TradeSea to NinjaTrader 8 in 5 steps

  1. Activate the Rithmic login

    Sign in to R|Trader Pro once with the Rithmic username and password from your account issuer and accept the Rithmic market-data agreements. TradeSea signs these agreements inside its own connect dialog, so a login already used on TradeSea may have them. The direct PropFirmConnector setup below does not require R|Trader Pro to stay open.

  2. Install PropFirmConnector

    From your PropFirmConnector account, download PropFirmConnector.zip and close NinjaTrader completely. Extract the ZIP, then copy NinjaTrader.Custom-pfc.dll to My Documents\NinjaTrader 8\bin\Custom. Start NinjaTrader again and, when your browser opens, click Activate this device.

    Open your account downloads

    No license yet? Start the free 7-day trial, then download PropFirmConnector from your account.

  3. Open NinjaTrader 8 and sign in

    Start NinjaTrader 8 and sign in with your NinjaTrader account credentials when prompted. These are your NinjaTrader credentials, not the Rithmic username and password issued by TradeSea.

  4. Configure Rithmic for TradeSea

    In the NinjaTrader Control Center, select Connections, then configure. Select Rithmic for NinjaTrader Brokerage from the Available list on the left, enter the Rithmic username and password issued by TradeSea, give the connection a recognizable name, leave Connect on start up and Plug-in mode off, and select tradesea for System.

  5. Connect to TradeSea

    Open Connections again and click the connection name you just created. A green status indicator and the account appearing in NinjaTrader confirm the connection.

If your TradeSea connection is not working

Should Plug-in mode be on or off?
Off. Plug-in mode shares a running R|Trader Pro session with NinjaTrader, which is a different setup from PropFirmConnector’s direct connection. In Connections > Configure, select your Rithmic connection, uncheck Plug-in mode, click OK and connect again. Some firm and Rithmic instructions turn it on for their R|Trader Pro workflow; leave it off for PropFirmConnector.
The connection is green, but the account isn’t in NinjaTrader’s Accounts tab.
Your NinjaTrader login is probably missing the general Rithmic entitlement, so the Accounts tab often shows only Sim101. In NinjaTrader, open Help > About. The Entitlements line should say Evaluation (Rithmic); if it doesn’t, the connection can turn green without showing your accounts. Older NinjaTrader accounts don’t have this entitlement by default, but newly registered accounts do. The fix is in your NinjaTrader account, not in Rithmic or your firm’s dashboard, and you only do it once.
About NinjaTrader window with Entitlements showing Evaluation (Rithmic).
Correct: Entitlements lists Evaluation (Rithmic). Machine ID and User are hidden.

If Evaluation (Rithmic) is missing:

  • Import this license key at account.ninjatrader.com: click your initials, then Settings > Plans > Import license key. Paste the key, click Import, then close and restart NinjaTrader.

  • No Import license key button, or still missing? Trading mainly with prop firms? Your NinjaTrader login doesn’t matter, so the fastest fix is to create a new NinjaTrader account with a different email and sign in with it.
  • Keeping your current login, for example because it has a live account on it? Email platformsupport@ninjatrader.com with your NinjaTrader username and ask them to enable the general Rithmic entitlement.

Your prop-firm login fails with System tradesea.
Accounts from TradeSea’s partner firms use the firm’s own System, not tradesea. Open that firm’s connection guide for its System.
Rithmic rejects the credentials.
TradeSea notes that credentials are case-sensitive: use the firm’s Rithmic username and password rather than another platform’s login, and retry after a password reset.

TradeSea + NinjaTrader questions

Q Can I use the accounts I trade on TradeSea in NinjaTrader?

Yes, with PropFirmConnector and the Rithmic credentials from the firm that issued the account. Select that firm’s System, which its connection guide lists.

Q When do I select tradesea for System?

Select tradesea only for Rithmic credentials issued on TradeSea’s own system. It is TradeSea’s entry in PropFirmConnector’s Firm list; NinjaTrader’s built-in Rithmic System list does not include it.

Q Can I use my TradeSea sign-in in NinjaTrader?

No. TradeSea signs in with Google, Apple or an emailed code. NinjaTrader connects with the Rithmic username and password your account issuer provides.

Q Is PropFirmConnector affiliated with TradeSea?

No. PropFirmConnector is an independent NinjaTrader add-on and is not affiliated with or endorsed by TradeSea, NinjaTrader, or Rithmic.
