If you trade futures and want to analyze order flow with footprint charts, the two platforms you’ll compare most often are NinjaTrader and ATAS. Both display bid/ask volume at individual price levels, both offer delta analysis, and both have active communities. But they differ significantly in architecture, pricing, customization depth, and ecosystem.
This comparison breaks down the differences that actually matter for your trading: feature depth, performance, flexibility, and total cost of ownership. We’ll also cover where third-party NinjaTrader tools like SidiFootprint close the gaps and where ATAS maintains genuine advantages.
Platform Architecture: Standalone vs. Ecosystem
The fundamental difference between ATAS and NinjaTrader is their design philosophy.
ATAS is a standalone order flow analysis platform. It was built from the ground up for footprint charts, cluster analysis, and volume-based trading. Everything revolves around order flow visualization. ATAS connects to exchanges directly or through data providers and offers its own charting, execution, and analysis tools in one package.
NinjaTrader is a general-purpose trading platform with order flow capabilities. It handles charting, backtesting, automated strategy development, and trade execution across multiple asset classes. Order flow tools are part of the broader ecosystem, available through the built-in Order Flow+ suite and hundreds of third-party indicators.
This distinction matters because ATAS gives you a focused, purpose-built experience for order flow, while NinjaTrader gives you order flow within a platform you can also use for backtesting, strategy automation, and multi-instrument analysis. If all you do is read footprint charts, ATAS gets you there quickly. If you need footprint analysis as part of a larger trading workflow, NinjaTrader is more versatile.
Footprint Chart Features: Head-to-Head
Display Modes
ATAS offers over 400 cluster chart types, including Bid/Ask, Delta, Volume, Trades, Time, and several proprietary visualizations. The sheer variety is impressive, though most traders use only 3-5 regularly.
NinjaTrader (built-in) provides BidxAsk display through Volumetric Bars. The built-in implementation covers the essentials but has limited visualization options.
NinjaTrader + SidiFootprint offers six display modes per profile (Volume, Delta, Delta %, Ask, Bid, Trades) with three rendering styles (Brick, Volume Bar, Volume Profile). The dual-profile system lets you run two different views simultaneously, for example BidxAsk on the left and Delta on the right, on the same chart.
Imbalance Detection
ATAS highlights volume imbalances with configurable thresholds. Diagonal imbalances (comparing bid at one level to ask at the level above/below) are the default calculation method. Cluster search functionality lets you scan for specific imbalance patterns across time.
NinjaTrader + SidiFootprint offers both diagonal and horizontal imbalance calculation modes, configurable percentage thresholds (default 300%), minimum volume filters, and automatic stacked imbalance zone tracking. Stacked zones extend forward as support/resistance until tested or broken, a feature that ATAS requires separate indicators to replicate.
VPOC and Value Area
ATAS tracks VPOC and Value Area within its standard volume analysis tools. Historical VPOC visualization is available.
NinjaTrader + SidiFootprint provides naked VPOC tracking (unretested VPOCs extended forward automatically), delta-based VPOC coloring (showing whether the VPOC formed under buying or selling pressure), and naked Value Area tracking. The delta-based VPOC coloring is a differentiator that ATAS doesn’t offer natively.
Proprietary Features
ATAS advantages:
- Cluster Search: scan historical data for specific order flow patterns
- Smart Tape: filtered time and sales with color-coded large orders
- Market depth history visualization
- Over 400 chart types for specialized analysis
NinjaTrader + SidiFootprint advantages:
- Market Memory Zones: proprietary algorithm identifying high-probability reaction zones based on VPOC position, bar structure, wick conditions, and volume
- 910+ individual settings for granular customization
- Absorption and exhaustion detection with configurable volume filters
- Dual-profile system with independent configuration per profile
- Full alert system: sound, text-to-speech, and email for delta events, volume thresholds, and zone breaks
Performance and System Requirements
ATAS is generally well-optimized for order flow data processing. However, loading extensive historical data with all cluster types enabled can strain system resources. ATAS runs only on Windows.
NinjaTrader also runs on Windows. Performance depends heavily on which indicators you’re running and how many charts are open. The built-in Volumetric Bars are lightweight. Third-party footprint indicators vary. SidiFootprint is optimized to work without Tick Replay, which significantly reduces data load and CPU usage compared to indicators that require it.
A key performance difference: NinjaTrader’s Tick Replay feature doubles your data processing load. If a footprint indicator requires it, your system needs to handle that overhead. SidiFootprint’s ability to operate without Tick Replay means lower latency and less resource consumption, especially on systems running multiple charts or instruments.
Pricing Comparison
This is where the comparison gets interesting:
ATAS:
- Free plan: basic footprint charts (limited features, delayed data)
- Standard: ~$85/month or ~$720/year
- Premium: ~$180/month for full feature access
- Includes platform + data for supported exchanges
NinjaTrader:
- Free version: basic charting, simulated trading
- Order Flow+ (Volumetric Bars): included with Lifetime license ($1,099 one-time) or $99/month subscription
- SidiFootprint: separate purchase from TPTE, with a free 14-day trial
- Data feed: NinjaTrader Continuum (included with funded accounts) or third-party
Long-term cost: NinjaTrader’s Lifetime license makes it cheaper over time. You pay once for the platform and can add/swap indicators as needed. ATAS’s subscription model means ongoing monthly costs that accumulate. Over two years, NinjaTrader + SidiFootprint typically costs less than ATAS’s standard subscription.
Ecosystem and Flexibility
ATAS is a closed ecosystem. You get what ATAS offers, and customization is limited to the settings they expose. If you need a feature that isn’t built in, you’re waiting for ATAS to add it.
NinjaTrader has an open ecosystem built on NinjaScript (C#). Hundreds of third-party developers create indicators, strategies, and tools. If you need something specific, there’s probably an add-on for it, or you can build it yourself. This extends beyond order flow: you can add custom execution tools, market scanners, automated strategies, and integration with external data sources.
For order flow specifically, the NinjaTrader ecosystem includes multiple footprint indicators (SidiFootprint, OrderFlow Trader, GomFP, and others), each with different strengths. You can choose the tool that matches your trading style rather than adapting to a single platform’s interpretation of order flow analysis.
Backtesting and Strategy Development
ATAS has limited backtesting capabilities. It’s primarily a real-time analysis and execution platform. If you want to backtest order flow strategies, you’ll need a separate tool.
NinjaTrader has a full backtesting engine with Strategy Analyzer, optimization, and walk-forward analysis. You can code strategies in NinjaScript that use order flow data as inputs, backtest them against historical tick data, and deploy them live. This is a significant advantage for traders who want to validate their order flow setups systematically.
When to Choose ATAS
ATAS is the better choice if you want a dedicated, purpose-built order flow platform with minimal setup, you primarily trade on non-CME exchanges where ATAS has better data coverage, you don’t need backtesting or strategy automation, and you prefer a subscription model without large upfront costs.
When to Choose NinjaTrader
NinjaTrader is the better choice if you want order flow analysis within a comprehensive trading platform, you value the ability to backtest and automate strategies, you prefer a one-time license cost over ongoing subscriptions, you want access to a deep ecosystem of third-party tools and indicators, and you need flexibility to customize every aspect of your charts and analysis.
With SidiFootprint, NinjaTrader matches or exceeds ATAS on footprint chart features while offering the broader platform capabilities (backtesting, automation, multi-instrument analysis) that ATAS lacks.
The Bottom Line
Both ATAS and NinjaTrader are capable order flow platforms. ATAS wins on out-of-the-box simplicity and the sheer number of built-in cluster chart types. NinjaTrader wins on ecosystem depth, long-term cost, backtesting capabilities, and customization.
For futures traders who want the deepest possible footprint analysis on NinjaTrader, SidiFootprint’s 14-day free trial lets you compare directly. Install it alongside NinjaTrader’s built-in Volumetric Bars, run them on the same chart, and see the difference that 910+ settings, dual profiles, and automatic zone tracking make for your trading decisions.
