DayTraders Platforms: ONYX & Rithmic Guide (2026)

Quick Answer Block

Platforms Cluster Disclaimer

Platform research verified: I've reviewed DayTraders' proprietary ONYX platform and their Rithmic connectivity options by examining their documentation, setup guides, and community feedback. This covers what platforms work, what doesn't, and the hidden costs most traders miss.

DayTraders supports ONYX (browser-based), rTrader Pro, and several third-party platforms via Rithmic — but not all platforms work with all account types. My full DayTraders platform guide covers compatibility, setup, and execution quality. For the full picture, read my complete DayTraders review. For the absolute latest, check DayTraders' website or their help center.

DayTraders provides three categories of trading platforms: their proprietary ONYX browser-based application, Rithmic's native rTrader Pro (desktop and mobile), and over ten third-party platforms that connect through Rithmic's data and execution infrastructure.

I've tested platforms across a lot of prop firms at this point, and DayTraders' setup is one of the more flexible ones. ONYX is genuinely impressive for a browser tool. But the platform landscape gets complicated fast once you factor in account types, add-on costs, and the restrictions on S2L live accounts.

This article is the central guide for everything platform-related at DayTraders. If you're trying to figure out what to trade on, start here.

What Platforms Does DayTraders Offer?

As of April 2026, DayTraders supports the following platforms:

Free with every account:

• ONYX (proprietary, browser-based)
• rTrader Pro (Rithmic desktop application)
• rTrader Pro Mobile (iOS and Android)

Third-party platforms via Rithmic (additional licensing may apply):

• Quantower
• MotiveWave
• VolFix
• Sierra Chart
• Jigsaw Daytradr
• Finamark
• ATAS (Advanced Trading Analytical Software)
• WealthCharts
• BookMap
• EdgeProX

NOT supported on S2L live accounts:

• NinjaTrader
• Tradovate

That last point catches a lot of people off guard. If you plan on eventually trading a DayTraders S2L live account and you're a NinjaTrader user, you need to plan your transition now. Not after you've passed the evaluation.

How Does ONYX Work at DayTraders?

ONYX is DayTraders' proprietary trading platform. It runs entirely in your web browser with no downloads or installations required. Under the hood, it combines TradingView's charting engine with Rithmic's real-time data feed and execution layer.

The result is a platform that looks and feels like TradingView but executes orders through Rithmic's infrastructure. DayTraders claims sub-millisecond order execution, and from what I've seen in community feedback, the execution speed holds up well for futures trading.

Key ONYX features:

• Browser-based with no software installation
• TradingView charting (same interface most traders already know)
• Rithmic real-time data and order routing
• One-click trading from the chart
• Enterprise-grade security (all processing happens server-side)
• Works on every DayTraders account type including S2L live

ONYX is the only platform DayTraders builds and maintains themselves. Every other option routes through Rithmic's third-party connectivity. That distinction matters because DayTraders has the most control over ONYX's performance and can push updates without waiting on external vendors.

How Does rTrader Pro Work at DayTraders?

rTrader Pro is Rithmic's native trading application. It's the desktop client that connects directly to Rithmic's servers, and DayTraders includes it free with every account.

rTrader Pro isn't flashy. The interface looks dated compared to modern platforms. But it's fast, stable, and does what it needs to do. This is the tool Rithmic built for their own infrastructure, so the connection is as direct as it gets.

The mobile version (rTrader Pro Mobile) gives you basic order management and position monitoring on your phone. I wouldn't execute a full trading session on mobile, but it's useful for checking positions and closing trades if you're away from your desk.

One feature that's unique to rTrader Pro at DayTraders: the built-in trade copier. For $10/month, you can copy trades from one DayTraders account to another through rTrader Pro. There's a catch, though. You can't combine DayTraders' trade copier with any other third-party copier. It's one or the other.

Which Third-Party Platforms Connect Through Rithmic?

DayTraders uses Rithmic as their data and execution provider, which opens the door to any platform with native Rithmic connectivity. As of April 2026, the confirmed compatible platforms are:

Quantower is probably the most popular choice among DayTraders users who want more than ONYX offers. It's a multi-asset platform with advanced charting, DOM trading, and volume analysis tools. Quantower has a free tier with limited features and paid plans for the full package.

Sierra Chart is the power user's pick. It's lightweight, fast, and highly customizable. The learning curve is steep, but traders who invest the time swear by it. Sierra Chart licenses start around $26/month.

MotiveWave sits at the premium end. It offers Elliott Wave analysis, advanced fibonacci tools, and a clean interface. Pricing varies by edition.

Jigsaw Daytradr is purpose-built for order flow trading. If you trade off the DOM and want depth-of-market analysis tools, Jigsaw is the standard.

BookMap is another order flow tool with a visual approach to market depth. It shows liquidity as a heatmap, which some traders find more intuitive than traditional DOM displays.

VolFix, ATAS, Finamark, WealthCharts, and EdgeProX round out the list. Each has its niche. VolFix and ATAS are popular for volume profile and cluster analysis. WealthCharts caters to technical analysis with a modern interface. Finamark and EdgeProX serve more specialized use cases.

I've written a detailed Rithmic setup guide for DayTraders that covers connection steps, server selection, and troubleshooting for each of these platforms.

What Platforms Are NOT Compatible with DayTraders?

NinjaTrader and Tradovate do NOT work on DayTraders S2L live accounts. This is a hard restriction.

You can use NinjaTrader during evaluations and on Trail, Static, and S2F accounts. But the moment you qualify for S2L live funding, NinjaTrader drops off the list. DayTraders hasn't given a detailed public explanation for this restriction, but it likely comes down to the different execution and clearing infrastructure used for live accounts.

If NinjaTrader is your primary platform, you have two realistic options:

1. Use NinjaTrader on Trail/Static/S2F and plan to switch to ONYX or another Rithmic platform if you move to S2L live.
2. Start with ONYX or a Rithmic-compatible platform from the beginning so there's no transition.

My recommendation: don't build your muscle memory around a platform you'll be forced to abandon. If S2L live is your goal, start with ONYX or Quantower.

How Does Platform Compatibility Vary by Account Type?

Not every platform works on every DayTraders account type. Here's the compatibility matrix:

The pattern is clear: everything works everywhere except NinjaTrader and Tradovate on S2L live. If you trade on Trail, Static, or S2F accounts exclusively, platform choice is wide open.

What Are the Add-On Costs for DayTraders Platforms?

DayTraders bundles ONYX and rTrader Pro for free. But there are optional add-ons that can add up:

Second Rithmic Login — $30/month By default, you get one Rithmic login per account. If you want to run two platforms simultaneously on the same account (say, ONYX for charting and Quantower for execution), you'll need a second login. At $30/month, that's a meaningful recurring cost.

Market Depth Data — $10 to $30/month Standard data feeds include Level 1 quotes. If you want full depth-of-market data (Level 2), DayTraders charges $10 to $30 per month depending on the data package. Order flow traders using Jigsaw or BookMap will likely need this.

Trade Copier — $10/month Available exclusively through rTrader Pro. This lets you duplicate trades from one DayTraders account to another. Useful if you're running multiple evaluations with the same strategy. But you cannot combine DayTraders' built-in copier with any external trade copying software. Pick one.

Third-party platform licenses are separate. DayTraders doesn't charge for Rithmic connectivity itself, but whatever you connect to Rithmic has its own pricing. Sierra Chart, Quantower Pro, MotiveWave, BookMap subscriptions all come out of your pocket.

How Do You Set Up a Platform on DayTraders?

The setup process depends on which platform you choose.

ONYX Setup

This is the simplest option. Log in to your DayTraders dashboard, click the ONYX link, and you're trading. No download, no configuration files, no server selection. It opens in your browser and connects automatically.

ONYX works on Chrome, Edge, Firefox, and Safari. I'd recommend Chrome or Edge for the best performance, but it's not a hard requirement. You can trade from a Chromebook, a Mac, a Windows PC, or even a tablet.

rTrader Pro Setup

Download rTrader Pro from Rithmic's website. During login, you'll need your Rithmic credentials (provided by DayTraders in your account dashboard) and the correct server. DayTraders typically uses specific Rithmic server endpoints that are listed in your welcome email or help center article.

The mobile app follows the same login flow. Download from the App Store or Google Play, enter the same credentials, select the server.

Third-Party Platform Setup

For any Rithmic-compatible platform (Quantower, Sierra Chart, etc.), the process follows a standard pattern:

1. Install the platform from its vendor's website
2. Select Rithmic as the data/execution provider within the platform settings
3. Enter your DayTraders Rithmic credentials
4. Select the correct Rithmic server
5. Connect and verify data is flowing

The specific menu location differs by platform, but the information you need is always the same: Rithmic username, password, and server. DayTraders provides all three.

If you run into connection issues, my DayTraders Rithmic setup guide covers troubleshooting for each platform individually.

Which Platform Should You Choose at DayTraders?

There's no universal answer, but here's how I'd break it down by trader type:

Brand new to futures trading? Start with ONYX. Zero setup friction, familiar TradingView interface, and it works on every account type. You can always switch later.

Already comfortable with a Rithmic platform? Keep using it. If you're a Quantower or Sierra Chart user, there's no reason to change. Just plug in your DayTraders credentials and go.

Order flow trader? Jigsaw or BookMap, paired with DayTraders' market depth add-on. Budget an extra $10–$30/month for the data feed on top of your platform subscription.

Planning for S2L live accounts? Stick with ONYX, rTrader Pro, Quantower, Sierra Chart, or any Rithmic platform that isn't NinjaTrader or Tradovate. Don't build your workflow around a platform you'll lose access to.

Trading from multiple devices or traveling? ONYX is the obvious choice. Browser-based means you can trade from any computer with an internet connection.

Running multiple accounts? Consider rTrader Pro's trade copier ($10/month) if you want to mirror trades across DayTraders accounts. Remember: one copier system only, no stacking.

What Makes DayTraders' Platform Support Different from Other Prop Firms?

Most prop firms give you Rithmic credentials and leave you to figure out platforms yourself. DayTraders does that too, but they also built ONYX.

That's the differentiator. Having a proprietary browser-based platform means DayTraders controls the trading experience end to end. If there's an execution issue, they don't have to troubleshoot across three different software vendors. They can look at their own system and diagnose directly.

The S2L live restriction on NinjaTrader is a trade-off. It limits your options, but it also suggests DayTraders has specific infrastructure requirements for live-funded accounts that NinjaTrader's integration can't meet. Whether that bothers you depends entirely on what platform you use.

Compared to firms like Apex Trader Funding (which is tied to NinjaTrader/Tradovate) or Topstep (similar stack), DayTraders offers more platform flexibility through Rithmic. The ONYX addition puts them ahead on accessibility. No other prop firm I've reviewed has a browser-based platform with TradingView charting and Rithmic execution built in.

Frequently Asked Questions

Is ONYX Free to Use at DayTraders?

Yes. DayTraders includes ONYX at no additional cost with every account type, including Trail, Static, S2F, and S2L evaluations and live accounts. ONYX runs in your browser and requires no download or separate subscription. DayTraders developed ONYX as their proprietary platform, and there are no plans to charge for it as of April 2026.

Can You Use NinjaTrader with DayTraders?

DayTraders supports NinjaTrader on Trail evaluations, Static evaluations, S2F accounts, and S2L evaluations. NinjaTrader is NOT compatible with DayTraders S2L live funded accounts. If you plan to trade S2L live, you'll need to switch to ONYX, rTrader Pro, or another Rithmic-connected platform before your live account activates.

What Does the DayTraders Trade Copier Cost?

DayTraders offers a built-in trade copier through rTrader Pro for $10 per month. The copier duplicates trades from one DayTraders account to another. DayTraders does not allow combining their built-in copier with any external third-party trade copying software. You must choose one or the other.

Does DayTraders Support Mobile Trading?

DayTraders supports mobile trading through two options: ONYX (which runs in any mobile browser) and rTrader Pro Mobile (available on iOS and Android). Both connect to your DayTraders account using the same Rithmic credentials. ONYX in a mobile browser gives you TradingView charting, while rTrader Pro Mobile is more focused on order management and position monitoring.

How Much Does Market Depth Cost at DayTraders?

DayTraders charges between $10 and $30 per month for market depth (Level 2) data, depending on the package. Standard accounts come with Level 1 quotes only. Order flow traders using platforms like Jigsaw, BookMap, or ATAS will need to add market depth to see full depth-of-market information. The cost is per account, not per platform.

What Is the Second Login Add-On at DayTraders?

DayTraders provides one Rithmic login per account by default. If you want to run two platforms simultaneously on the same account (for example, ONYX for charting while executing on Quantower), you need to purchase a second login for $30 per month. Without it, logging in on a second platform disconnects your first session.

Can You Use Quantower with DayTraders?

Yes. Quantower connects to DayTraders through Rithmic and works on all account types, including S2L live accounts. Quantower offers a free tier with basic features and paid plans starting around $40 per month for advanced tools. DayTraders doesn't charge anything for the Rithmic connection itself. You just enter your DayTraders Rithmic credentials in Quantower's connection settings.

Does DayTraders Work with Sierra Chart?

Yes. Sierra Chart connects to DayTraders through Rithmic and is compatible with all DayTraders account types, including S2L live. Sierra Chart subscriptions start around $26 per month. DayTraders users typically select Rithmic as the data/trade service in Sierra Chart's settings and enter their DayTraders credentials to connect.

Can You Trade on DayTraders Without Downloading Software?

Yes. DayTraders' ONYX platform is entirely browser-based and requires no download whatsoever. ONYX runs on Chrome, Edge, Firefox, and Safari. You can trade from any device with a web browser and internet connection. ONYX includes TradingView charting and Rithmic execution, making it a complete trading solution without installing anything.

What Happens if You Exceed Your Rithmic Login Limit at DayTraders?

DayTraders gives you one Rithmic login per account. If you log in on a second platform without purchasing the $30/month second login add-on, your first session gets disconnected automatically. DayTraders doesn't charge a penalty for this. Your existing session simply drops, and you'd need to reconnect on the original platform if you want to go back.

The bottom line: DayTraders gives you more platform flexibility than most prop firms. ONYX is a genuine standout for browser-based trading, and Rithmic connectivity opens the door to virtually every serious futures trading platform. Just watch the S2L live restrictions if NinjaTrader is your tool of choice, and budget for add-ons like market depth and second logins if your setup requires them.
