DayTraders Platforms: ONYX & Rithmic Guide (2026)

DayTraders supports a wider platform stack than most futures prop firms. The proprietary ONYX browser platform pairs with rTrader Pro and 10-plus third-party tools accessed through Rithmic. Choice creates flexibility but also creates compatibility traps, particularly the NinjaTrader-on-S2L-Live restriction that catches new funded traders off guard.

This guide covers every supported platform, the compatibility matrix across Trail, Static, S2F, S2L Evaluation, and S2L Live account types, add-on costs (market depth, second logins, trade copier), peer comparison against Topstep and Apex on platform breadth, and the practical decision matrix for choosing the right platform for your strategy.

Platform compatibility matrix

The critical column is S2L Live. NinjaTrader and Tradovate are unavailable on Live funded accounts, which means S2L traders must migrate to a Rithmic-compatible platform before live activation. Most traders default to ONYX or rTrader Pro for the migration since both are free and proprietary to DayTraders' infrastructure.

ONYX, the browser-native platform

ONYX runs entirely in the browser with no download required. The platform combines TradingView charting with Rithmic execution, producing a complete trading workflow accessible from any device with a web browser and internet connection. DayTraders developed ONYX internally and includes it at no cost across every account type.

ONYX is the default for traders who value cross-device flexibility or do not want to install desktop software. The browser footprint means trading from a phone, tablet, or any temporary workstation works without configuration changes. The trade-off is that browser-based platforms tend to lag desktop platforms by 50-150ms on order entry latency, which matters for high-frequency strategies but not for typical discretionary day trading.

ONYX feature highlights

• TradingView charting integrated natively, no separate subscription required
• Rithmic execution layer with sub-200ms order routing typically
• Mobile-responsive interface for trading from phone or tablet
• Free across Trail, Static, S2F, S2L Eval, and S2L Live
• No software install or driver configuration required
• Multi-account view for traders running parallel DayTraders accounts

rTrader Pro and the Rithmic ecosystem

rTrader Pro is Rithmic's first-party desktop trading interface. DayTraders bundles rTrader Pro at no cost and connects it through Rithmic to the trader's DayTraders account. The desktop interface trades raw simplicity for lower latency and tighter integration with Rithmic-specific features like depth-of-market and conditional order types.

rTrader Pro is the right default for traders who prefer desktop platforms but do not want to pay for Sierra Chart or NinjaTrader subscriptions. The feature set is narrower than third-party alternatives but the cost is zero and the connection stability is the strongest in the stack since rTrader Pro is Rithmic's own product.

Third-party platforms accessed via Rithmic

Quantower, Sierra Chart, MotiveWave, Jigsaw, BookMap, NinjaTrader, and Tradovate all connect to DayTraders through Rithmic data and execution routing. The platform you choose handles the chart visualization, order entry workflow, and analysis tools. The underlying data feed and trade execution remain Rithmic-routed regardless of which interface you select.

Quantower

Quantower offers a free tier with basic features and paid plans starting around $40 per month. Compatible with all DayTraders account types including S2L Live. The platform sits in the middle of the depth-versus-simplicity spectrum, more capable than rTrader Pro, lighter weight than Sierra Chart. Popular with discretionary traders who want strong charting without Sierra's learning curve.

Sierra Chart

Sierra Chart subscriptions start around $26 per month with additional packages for specific features. Compatible across all DayTraders account types. The platform is preferred by quantitative traders who need raw tick data, advanced backtesting, and Spreadsheet-based scripting. Steepest learning curve in the stack but deepest analytical capability.

Jigsaw and BookMap for order-flow

Jigsaw at roughly $379 lifetime and BookMap with free tier or paid plans starting around $39 per month both specialize in order-flow visualization and depth-of-market analysis. Compatible across all DayTraders account types. Required by traders running tape-reading or volume-profile strategies who need to see real-time book depth changes. Note that Level 2 market depth data is a separate add-on cost from DayTraders ($10-30 per month).

NinjaTrader and Tradovate restrictions

Both NinjaTrader and Tradovate work on Trail, Static, S2F, and S2L Evaluation accounts. Neither is supported on S2L Live funded accounts. The restriction is platform-side, not strategy-side, S2L Live traders simply cannot connect these specific platforms to their funded accounts. Plan migration to ONYX, rTrader Pro, Quantower, or Sierra Chart before S2L Live activation.

Add-on cost matrix

Most discretionary traders need only the base platform plus Level 1 quotes, total monthly cost around zero on ONYX or rTrader Pro. Order-flow specialists add market depth ($10-30) plus a visualization platform like BookMap or Jigsaw, total monthly cost $40-70. Multi-platform traders add the second Rithmic login ($30) on top of the rest.

Mobile trading options

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.

Mobile is best treated as a monitoring and emergency-exit tool rather than the primary execution platform. Latency on cellular networks varies more than on dedicated desktop connections, and the smaller screen reduces situational awareness. Traders who actively scalp from mobile typically take more session-pause losses than traders on desktop interfaces with the same strategy.

Platform decision matrix by trader profile

The decision matrix above is a starting framework. Individual preferences around interface aesthetics, hotkey customization, and specific charting features will refine the choice. Most traders end up running a primary platform plus a secondary mobile or backup platform rather than a single-platform setup.

Peer comparison vs Topstep and Apex on platform breadth

DayTraders sits at the broad end of the platform-breadth spectrum among futures props. The combination of proprietary ONYX (browser-based) plus rTrader Pro (desktop) plus 10+ third-party Rithmic-routed options gives traders the widest interface choice in the sector. Topstep's TopstepX is also browser-native and well-integrated but with narrower third-party platform support.

Setup and onboarding workflow

ONYX onboarding takes under five minutes. Log into the DayTraders portal, click the ONYX tile, and the browser interface loads with your account credentials pre-populated. No download, no configuration, no Rithmic credential management. The simplest possible setup in the futures prop space.

Third-party platform onboarding requires Rithmic credential entry. Download the platform, install, then enter the Rithmic credentials provided by DayTraders. Configure the data feed and execution routing to match the DayTraders account type (eval versus funded). Typical first-time setup takes 30-60 minutes including platform installation, credential entry, and initial layout configuration.

Common setup mistakes

• Entering Rithmic credentials in production mode while account is still in evaluation mode (or vice versa)
• Forgetting to switch the data feed from demo to live after passing evaluation
• Running NinjaTrader connected to an S2L Live account, which is not supported
• Sharing Rithmic credentials across multiple platforms simultaneously without purchasing the second login add-on
• Skipping the platform-level alert configuration before first trading session
• Not testing the chosen platform on a demo account before risking eval capital

Trade copier and multi-account workflow

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. The built-in copier handles the common multi-account scaling use case for traders running 2-5 parallel DayTraders accounts.

External copier services that traders sometimes try to layer on top of rTrader Pro will trigger a platform-side compliance flag. The result can range from a warning to permanent account closure depending on how aggressively the external copier interacts with the Rithmic feed. Stick with the built-in option for compliance certainty.

Cost projection across a year of platform usage

The annual platform cost spread runs zero to roughly $1,400 depending on configuration. Most discretionary traders stay under $400 per year. Full order-flow and quant setups can exceed $1,000. Plan the platform stack early since adding subscriptions mid-year does not unlock retroactive features and the costs accumulate quickly.

Hardware and connectivity recommendations

Browser-based ONYX runs effectively on modest hardware, any reasonably modern laptop with 8GB RAM and Chrome or Firefox handles full charting and execution. Desktop platforms like Sierra Chart and NinjaTrader benefit from 16GB RAM and SSD storage when running multiple charts, tick-by-tick data feeds, or backtesting. Multi-monitor setups (2-3 displays) materially improve productivity for active traders monitoring multiple instruments or timeframes simultaneously.

Connectivity matters more than raw hardware for execution quality. A stable wired ethernet connection delivers consistently lower latency than wireless. VPN routing can add 50-150 milliseconds depending on geography. For traders running scalping strategies, the connection setup matters more than the platform choice in terms of fill quality. Verify connection stability before committing to high-frequency strategies on the platform.

Algorithmic trading and API access

DayTraders supports algorithmic trading through Rithmic-compatible platforms that expose programmatic order interfaces. NinjaTrader's NinjaScript and Sierra Chart's Advanced Custom Study Language (ACSL) are the two most common scripting environments. Quantower also supports algorithmic trading through its API. ONYX and rTrader Pro do not natively support custom algo development.

Algo traders typically build and backtest in Sierra Chart or NinjaTrader during the evaluation phase, then migrate to a Rithmic-compatible Live platform if their algo logic is portable. NinjaTrader's S2L Live restriction means algo traders using NinjaScript must port their algos to a different platform before Live activation, which is a meaningful engineering cost worth planning for at evaluation purchase rather than at activation time.

API and connectivity options

Direct API access to Rithmic data and execution is available for traders who want to build custom interfaces or integrate with external systems. The API documentation is available through Rithmic with DayTraders providing connection credentials. Most traders do not need direct API access since the supported platforms cover the common workflow patterns, but for institutional-style traders or developers, the option exists.

Backup platform strategy and redundancy

Active funded traders benefit from having a backup platform configured before they need it. The most common pattern is to run ONYX or rTrader Pro Mobile as the backup for whatever primary desktop platform is used. The backup serves two purposes: emergency position management if the primary platform crashes, and trading from non-primary locations (travel, alternate workstations) without setup overhead.

Backup configuration takes 10-15 minutes after the primary is established. Test the backup at least once per month by closing a small position from it to verify the credentials and connection still work. Discovering the backup is broken during a primary outage is a meaningful trading-day-killer, especially during high-volatility sessions where position management cannot wait.

Migration path from NinjaTrader to ONYX or rTrader Pro

Traders who use NinjaTrader during evaluation and then advance to S2L Live face a forced migration since NinjaTrader is unsupported on Live accounts. The migration path most traders follow is NinjaTrader to ONYX during the final week of evaluation, with side-by-side comparison sessions to validate that order entry hotkeys and chart layouts feel acceptable before Live activation.

Practical migration tips: replicate the NinjaTrader chart layout in ONYX or Quantower at least one week before Live activation. Trade a few demo sessions on the new platform with identical instrument and timeframe setup. Confirm hotkey workflows feel natural before risking funded capital. Most migration friction comes from muscle memory around hotkey layouts rather than from platform feature gaps.

Charting feature comparison across platforms

ONYX's TradingView integration gives it the broadest indicator library of any DayTraders platform option since the TradingView community has thousands of public indicators. The trade-off is that ONYX's charting engine is read-only on those indicators, custom modification requires moving to a platform with native scripting like Sierra Chart or NinjaTrader.

For order-flow analysis (footprint, volume profile, bid-ask delta), Quantower paid tier and Sierra Chart deliver the most complete feature set. BookMap specializes in order-flow visualization but does not handle traditional candle charting as effectively as the dual-purpose platforms. Order-flow traders typically run BookMap alongside Quantower or Sierra Chart rather than as the sole platform.

Platform performance benchmarks

DayTraders does not publish official latency benchmarks across its platform stack. Anecdotal trader reports place ONYX in the 200-350 millisecond range for order routing from button-press to fill confirmation, rTrader Pro in the 100-200 range, and Sierra Chart and NinjaTrader in the 80-180 range depending on configuration. The differences are small in absolute terms but accumulate across thousands of trades per year for active traders.

For typical retail strategies executing 5-30 trades per day, the latency variation between platforms does not materially affect outcomes. For high-frequency strategies executing 100-plus trades per day with tight time-in-trade, choosing a desktop platform with optimized configuration can save 1-3 ticks per round-turn compared with browser-based ONYX. The compound effect over 10,000 annual trades is meaningful, perhaps $5,000-15,000 in saved slippage on active scalping accounts.

Platform-specific data feed considerations

Rithmic operates as the underlying data and execution backbone for all DayTraders platforms. The data feed itself is identical across ONYX, rTrader Pro, Sierra Chart, and the other third-party platforms. What varies is how each platform consumes and displays that data. Sierra Chart accesses Rithmic tick-by-tick data with full detail. ONYX accesses the same feed but renders it through browser-based aggregation that may smooth or batch tick events for performance reasons.

For traders running volume-profile, order-flow, or footprint chart strategies, the tick-by-tick fidelity matters. Sierra Chart and BookMap typically deliver the highest-fidelity tick rendering. Quantower and NinjaTrader sit in the middle. ONYX is the lowest-fidelity option but adequate for typical price-action and indicator-based strategies that do not require sub-tick precision.

Hotkey and workflow customization across platforms

Hotkey support varies significantly across the DayTraders platform stack. Sierra Chart and NinjaTrader offer the deepest customization including chained hotkey sequences, conditional triggers, and scriptable workflows. Quantower offers moderate customization. ONYX and rTrader Pro offer basic hotkey support sufficient for typical order entry but limited for complex multi-step workflows.

Traders building specific muscle memory around hotkeys should commit to one platform early rather than switching between platforms with different hotkey conventions. Switching costs are higher than most traders expect, the productivity hit during transition typically lasts 2-4 weeks before new hotkey patterns become automatic.

Bottom line

DayTraders offers one of the broadest platform stacks in the futures prop space. ONYX is the default browser-based option, free across all account types and the simplest setup in the sector. rTrader Pro covers the free desktop use case. Quantower, Sierra Chart, MotiveWave, Jigsaw, BookMap, NinjaTrader, and Tradovate handle the third-party preferences via Rithmic routing. NinjaTrader and Tradovate are unsupported on S2L Live funded accounts, plan migration before activation.

Add-on costs (market depth, second logins, trade copier) range from $0 for basic discretionary setups to roughly $115 per month for full quant configurations. Most traders fall in the $10-50 per month range. Setup time is under five minutes on ONYX and 30-60 minutes for third-party platforms. The breadth of options is a strength but requires deliberate platform selection rather than defaulting to whatever feels familiar.

For new traders entering DayTraders, the recommended starting platform is ONYX. Free, browser-based, zero setup overhead, and compatible with every account type including S2L Live. Once the trader has 30-60 days of platform familiarity and clear strategy direction, the decision about whether to invest in Sierra Chart, BookMap, or a paid Quantower tier becomes meaningful. Until then, ONYX covers 80-90% of typical retail futures trading needs without subscription cost.

Experienced traders migrating from other prop firms typically have an existing platform preference. DayTraders supports most common preferences (Sierra Chart, NinjaTrader for evaluation, Quantower, rTrader Pro) so the migration usually involves credential setup rather than platform learning. The notable exception is traders coming from Tradovate-centric firms like Bulenox or pre-2026 Topstep, where Tradovate familiarity may need to translate to ONYX or rTrader Pro for S2L Live continuation.

The platform stack at DayTraders rewards traders who think about their specific workflow needs rather than defaulting to whatever interface they used last. Order-flow specialists who need BookMap or Jigsaw will find the path well-supported. Algorithmic traders building in NinjaScript or Sierra Chart's ACSL have full evaluation-phase support but need migration planning for S2L Live. Discretionary intraday traders get the simplest setup through ONYX with no compromises on functionality for typical retail use cases.

Across the broader futures prop landscape, DayTraders' platform breadth is a structural advantage versus firms like MyFundedFutures or Bulenox that support a narrower set. The advantage is real but only matters if you specifically want a platform that those competing firms do not support. For traders happy with Tradovate or NinjaTrader on evaluation, the breadth advantage at DayTraders is less compelling than the specific rule architecture of the funded program itself. Platform selection should be one input among several when evaluating which futures prop firm to commit to, not the dominant criterion.

The most common platform configuration for established DayTraders funded traders is ONYX as the always-on dashboard plus a desktop platform (Quantower, Sierra Chart, or rTrader Pro) for active session trading. The dual-platform setup uses the second Rithmic login at $30 per month to keep both running simultaneously. Total monthly platform cost on this typical configuration runs $30-90 depending on the desktop platform chosen, well within the economics of a profitable funded account producing $1,000-3,000 monthly take-home.

For new traders unsure which configuration to commit to, start with ONYX only for the first 30 days, evaluate where the platform falls short of your specific workflow needs, then add exactly the additional platform that addresses the gap rather than purchasing a broader stack upfront. The staged approach prevents over-paying for platform features that go unused in practice. Most traders find that the perceived need for a paid platform shrinks once they have spent meaningful time with ONYX's free feature set.

The full implications of these structural features compound across multi-year engagements. Traders committing to a single firm for 12-plus months see the cumulative effect of every individual rule and cost component, the headline numbers in early-engagement comparison rarely capture the year-two and year-three economics. Plan against the long-horizon view rather than the first-month look when committing to any specific prop firm choice.

Frequently Asked Questions

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. It is the default platform for new traders learning the DayTraders ecosystem.

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 will need to switch to ONYX, rTrader Pro, or another Rithmic-connected platform before your live account activates. Plan the migration at least one week before activation.

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 to stay compliant with platform terms.

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 focuses 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, you need to purchase a second login for $30 per month. Without it, logging in on a second platform disconnects your first session. The add-on is mandatory for traders running ONYX plus a desktop platform in parallel.

Can you use Quantower with DayTraders?

Yes. Quantower connects to DayTraders through Rithmic and works on all account types including S2L Live. Quantower offers a free tier with basic features and paid plans starting around $40 per month for advanced tools. DayTraders does not charge anything for the Rithmic connection itself, only the Quantower subscription costs apply.

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 and 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. 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 per month second login add-on, your first session gets disconnected automatically. DayTraders does not charge a penalty for this. Your existing session drops and you would need to reconnect on the original platform to continue trading from there.

How does DayTraders platform breadth compare to Topstep?

DayTraders supports 10+ platforms via Rithmic plus the proprietary ONYX. Topstep supports TopstepX (proprietary browser-based) plus a narrower third-party set. DayTraders offers broader choice, Topstep offers tighter integration within a smaller selection. For traders who prefer one specific third-party platform, DayTraders is more likely to support it. For traders who want simple defaults, Topstep is comparable.

Which platform has the lowest latency at DayTraders?

Desktop platforms like Sierra Chart, NinjaTrader, and rTrader Pro typically deliver lower latency than browser-based ONYX, with the gap usually in the 50-150 millisecond range. For typical discretionary trading the latency difference does not affect outcomes. For high-frequency scalping the desktop platforms produce measurably better fill quality on aggressive entries.

Can I run multiple DayTraders accounts on the same platform?

Yes, ONYX and rTrader Pro both support multi-account views where you can see and trade across several DayTraders accounts from one interface. For third-party platforms, each account typically requires its own Rithmic login configuration. The built-in trade copier at $10 per month handles multi-account synchronized order entry.

Do I need to pay for a platform during evaluation at DayTraders?

No. ONYX and rTrader Pro are free and cover the full evaluation phase across Trail, Static, S2F, and S2L Eval accounts. Third-party platform subscriptions (Sierra Chart, Quantower paid tier, BookMap, etc.) are optional. Most new traders run free platforms during evaluation and only add paid subscriptions after confirming the platform fit on funded accounts.

Is the DayTraders platform compatible with Mac?

ONYX is browser-based and runs on macOS without issue. rTrader Pro has historically been Windows-only with macOS support requiring workarounds like virtualization. Most third-party platforms (Sierra Chart, NinjaTrader, Quantower) are Windows-first with varying degrees of macOS compatibility. Verify Mac compatibility with the specific platform vendor before committing.

What is the DayTraders platform learning curve like?

ONYX is the lowest learning curve since it uses TradingView charting that most traders already recognize. rTrader Pro is moderate. Sierra Chart is the steepest in the stack but rewards the investment with the deepest feature set. Most traders are productive on ONYX within an hour and on Sierra Chart within several weeks of daily use.
