DayTraders.com and NinjaTrader 8: What the Firm Publishes, and the Rithmic Mechanics

DayTraders.com issues Rithmic credentials, and nothing else. Its help centre lists exactly one account type — “Rithmic Account” — and every product on its pricing builder checks out on a Rithmic slug, so there is no Tradovate product at any stage and no feed to pick at checkout. Your username and password sit in the member dashboard under “Platform Login Details”; those are the credentials you sign the Rithmic market data agreements with, and the same pair every platform the firm documents logs in with.

Before any of the mechanics matter, read what the firm itself publishes about NinjaTrader. In its Platform Connection Guides article, DayTraders states: “Please note that we currently DO NOT support Ninja Trader on any of our accounts.” Its Rithmic services article repeats the point — “As of today we don’t support Ninja Trader, MT4, MT5 or Tradingview.” — and the newest of the three, the live accounts article updated on 12 August 2026, says: “NinjaTrader and Tradovate are not supported for live accounts.” That is the firm’s position as written, and the first of those statements scopes itself to any of its accounts.

So the first practical step here is not a setting. Ask DayTraders what you may use on your account, and get that answer before you trade it — their terms govern your account, not ours and not a third party’s. Worth knowing alongside it: the firm’s connection guides close by saying it offers only limited support for platform issues and directs you to the platform vendor, and it publishes no NinjaTrader instructions of its own.

The rest of this page is the Rithmic side of the picture — what DayTraders issues, what it documents, and how NinjaTrader’s own general-purpose Rithmic connection is laid out — so that the conversation with the firm is a short one. The things that actually trip people up on this feed are ordinary Rithmic things: agreements not yet signed, the wrong row picked in a System dropdown, a trader classification chosen in a hurry, and a scheduled maintenance window that looks exactly like a broken account.

What DayTraders issues and which platforms it documents

• Rithmic, exclusively. The firm’s Rithmic services article states that “Rithmic accounts are designed to work exclusively with the Rithmic DMA broker”, which is what allows third-party platforms to connect at all. There is no second feed anywhere in the catalogue.
• One account type, two simulated stages. Evaluation account numbers read DT-xxxx-xx and Pro account numbers read PRO-DT-xxxx-xx, and both appear in the same dropdown on the same DayTraders system. Pro is not real money: “No, they are not live. They are simulated funds. They do not contain genuine live funds.”
• Live accounts are a separate case. After a Straight to Live evaluation the firm provides an Onyx license, and lists Quantower, ATAS, MotiveWave, EdgeProX, Sierra Chart and Bookmap as permitted if you already own a license. It publishes no gateway, broker or data provider for live accounts anywhere in its material, and it names NinjaTrader there only to exclude it. Allocation is discretionary — the firm says it transitions around 1% of traders who come through the sim funded programme — and its partners page footer draws the line as “Evaluation and Pro accounts are simulated and do not involve real capital. Live funded accounts through the S2L program involve real market execution.”
• The front ends it documents. Onyx, its own platform, described as “hosted and powered by Rithmic” with a license included; Quantower with a license included; MotiveWave with a license needed; plus ATAS, BookMap, Finamark, Jigsaw, Sierra Chart and VolFix, with WealthCharts and ArcTrader carrying their own guides. All of them sign in with the same Rithmic credentials.
• No NinjaTrader or Tradovate guide. The Trading Platforms collection runs to 25 articles, every connection guide named “… to Rithmic”, and neither platform has one.

What you need before you start

• An answer from DayTraders about what you may use on your account, given the statements quoted above. Keep it.
• Your Rithmic username and password from the member dashboard under “Platform Login Details”. They are case-sensitive, and the firm’s own guides warn twice about extra spaces picked up when you copy them.
• Your Rithmic agreements signed. Two CME Group documents appear on first rTrader Pro login. The second is your trader classification — DayTraders tells its users to select Non-Professional, and choosing otherwise raises your data fees.
• The account number you intend to trade, written down. DT-xxxx-xx is an evaluation, PRO-DT-xxxx-xx is a Pro account, and picking the wrong row in a dropdown is the most common self-inflicted error on this feed.
• A sensible time of day. Rithmic maintenance covers weekends and roughly 5:00–6:00 PM ET daily, and during those windows logins, agreement signing and credential access can all fail in ways that look like a fault.

How NinjaTrader’s Rithmic connection is laid out

NinjaTrader 8 includes a general-purpose Rithmic connection type, and the fields below belong to that connection type rather than to DayTraders. The firm publishes no NinjaTrader settings and states it does not support the platform on its accounts, so read this as a description of the mechanics, and take the instructions that apply to your own account from DayTraders.

1. Multi-Provider and the restart

In NinjaTrader 8, Multi-Provider lives under Tools > Settings > General, and it is what lets the platform run more than one connection provider at a time. It takes effect only after NinjaTrader is restarted, which is where most of the confusion around it comes from — the tick is saved, the behaviour has not changed yet.

2. The stock Rithmic connection type

Connection types are added and edited under Connections > Configure. Rithmic for NinjaTrader Brokerage is the entry in the Available list that takes Rithmic credentials. Name the connection something you will recognise later; an account number is a better label than a firm name if you ever keep more than one configured.

3. Credentials

The Rithmic connection takes a Rithmic username and password, typed or pasted exactly as issued. Case matters, and a trailing space carried over from a copy-paste fails authentication while looking perfectly correct on screen.

4. System and Gateway — the fields to check with the firm

This is where DayTraders’ published guidance and NinjaTrader’s general Rithmic convention do not line up, so do not guess. For the platforms it documents, DayTraders tells users to select the DayTraders entry as the System — written “DayTraders.com” in most of its articles and once as “Day Traders” — on the Chicago gateway, and it warns repeatedly against picking “Rithmic Paper Trading” or “Rithmic Paper Trader”.

DayTraders.com is a dedicated Rithmic system, listed in Rithmic’s own public system list, and NinjaTrader’s stock System dropdown does not include it. The generic Rithmic Paper Trading (Chicago) and Rithmic 01 (Chicago) entries that many other firms use are not DayTraders’ system, and those are the entries its guides tell you to avoid. NinjaTrader also has no separate Gateway field.

Since DayTraders publishes no NinjaTrader settings at all, what you may use on your account is a question for its desk rather than something to work out from a dropdown. Our general Rithmic connection guide explains what each of those fields does.

5. Verify what you are actually looking at

Whatever front end you end up on, check the account selector before you touch an order. The account number showing should be the DT- or PRO-DT- number you intended to trade, not another row that happens to sit above it. In the platforms DayTraders documents, a good connection reads back the DayTraders system plus the Chicago gateway and a “Connected” status, and the same habit applies anywhere: confirm the account, the market data status and the instrument you are quoting before anything goes to market.

Questions we get about DayTraders and NinjaTrader

DayTraders says it does not support NinjaTrader — what does that mean for my account?

It means the firm has stated a position in writing, three times, most recently on 12 August 2026, and that the earliest of those statements scopes itself to any of its accounts while the latest names live accounts specifically. We are not in a position to tell you what DayTraders permits on your account; only DayTraders can. Ask them directly what platforms you may use and keep the answer, and bear in mind their published line that platform support is limited and directed to the vendor.

I found a DayTraders NinjaTrader guide in a search result. Is it current?

No. The firm’s sitemap still lists one legacy page titled “connection guide for rithmic using ninjatrader 8 1 1 7” — the only remaining page of its kind among the 332 URLs there — and it now returns a 403, so it cannot be read. DayTraders published a NinjaTrader 8 and Rithmic guide at some point and has withdrawn it; the current help centre carries the statements quoted above instead. Separately, a February 2026 third-party review describes NinjaTrader as a route for this firm, and it predates all three of the firm’s statements; a commercial add-on vendor says the same thing and is contradicted by them. Prefer the firm.

Why does checkout talk about choosing a market data provider when there is no choice?

That is stale copy in an older products article, left over from a period when more than one feed was sold. Today every product checks out on Rithmic and the help centre lists a single account type. The same article carries two rules worth knowing: modifications to account type, size or market data provider are not possible once a purchase is finalised, and payment will not complete with a VPN switched on.

DayTraders markets TradingView charts but also says it does not support TradingView. Which is it?

Both, and they are not in conflict. Onyx and ArcTrader embed TradingView charting inside a Rithmic connection; TradingView as a broker connection in its own right is the thing the firm says it does not support. Readers trip on this constantly, so it is worth reading “supported platform” in that help centre as “supported broker connection”.

What does DayTraders publish about running it alongside another Rithmic firm?

Its own article on trading with multiple funding companies says that grandfathered multi-broker Rithmic license keys “available before July 15, 2014” allow several funding companies under one platform install, and that everyone else needs a separate VM or VPS; it presents that as a Rithmic licensing matter rather than one of its own rules. Treat it as the firm’s published description and confirm the current position with DayTraders and with Rithmic before you plan around it. Note too that the firm sells a second concurrent login session as a $30 a month add-on, and that its add-ons expire at 5:00 PM ET on the last day of the month regardless of when they were bought.

Nothing connects and the credentials look right

Check the clock first — the daily maintenance window and weekends account for a large share of these. Then check that both Rithmic agreements are signed, since an unsigned classification document will hold everything up. Then check you are on the account row you think you are. Our write-up of Rithmic logon failed messages in NinjaTrader covers the remaining causes in order of likelihood.
