What is Active Trader Pro?
Active Trader Pro is a professional-grade trading platform developed by Fidelity Investments, one of the largest and most trusted financial services companies in the U.S. Unlike Fidelity’s standard brokerage platform, which caters to casual investors, Active Trader Pro (ATP) is explicitly built for serious traders who need advanced tools, real-time data, and precise execution. It’s available as a downloadable desktop application for Windows and macOS, though its mobile app counterpart is far more limited in features.
Key Features of Active Trader Pro
Advanced Trading Tools
ATP offers real-time streaming quotes, customizable charts (with over 25 technical indicators like RSI, MACD, and Bollinger Bands), and a suite of order types. For example, traders can execute conditional orders (e.g., "Buy if the price drops to $X") or use basket trading to buy/sell groups of stocks simultaneously.
Fidelity Integration
The platform integrates smoothly with Fidelity accounts, giving users direct access to the brokerage’s proprietary research, market analysis, and educational resources. This includes tools like the ETF Screener for filtering funds by sector, risk level, or expense ratio and the Options Strategy Builder for visualizing complex options trades.
Directed Trade
A unique ATP feature for Fidelity customers, Directed Trade, lets you route orders directly to specific exchanges (e.g., NYSE or NASDAQ) to potentially get better execution prices—a perk for high-volume traders.
Cost Efficiency
ATP users benefit from Fidelity. There are no additional platform fees, which makes it cost-effective for frequent traders.
Who’s It For?
ATP is ideal for active stock and ETF traders, particularly those already invested in the Fidelity ecosystem. It’s also a solid choice for traders prioritizing low costs and reliable execution over flashy interfaces. However, it’s less suited for options traders or technical analysts who need more profound charting tools.

What is Thinkorswim?
Thinkorswim is a powerful, all-in-one trading platform initially developed by TD Ameritrade (now part of Charles Schwab) to cater to advanced traders, technical analysts, and options enthusiasts. Unlike essential brokerage platforms, Thinkorswim (TOS) is designed for traders who demand deep customization, sophisticated tools, and device flexibility. It’s available as a desktop application (Windows/Mac), a web-based platform, and a feature-rich mobile app, making it accessible for traders on the go.
Key Features of Thinkorswim
Advanced Charting and Analysis
Thinkorswim is renowned for its professional-grade charting tools. It supports over 100 technical indicators (e.g., Ichimoku Cloud, Fibonacci retracements) and 400+ drawing tools. Charts are fully customizable, allowing traders to overlay multiple timeframes, compare securities, and create custom studies using thinkScript (TOS’s proprietary coding language). For example, you can build automated alerts or backtest trading strategies.
Options Trading Tools
Thinkorswim dominates in options trading. Its Options Probability Lab calculates the likelihood of an option expiring in the money, while the Strategy Roller helps adjust complex multi-leg positions (e.g., iron condors, straddles). The platform also visualizes profit/loss scenarios in real-time, making it easier to manage risk.
Paper Trading
Unique to Thinkorswim is its paperMoney® feature, a simulated trading account with $100,000 in virtual funds. This allows traders to practice strategies risk-free, test new ideas, or get familiar with the platform before risking real money.
Custom Scans and Alerts
The platform includes a Stock Hacker tool for creating custom screens based on technical, fundamental, or social sentiment criteria (e.g., “Find stocks with RSI < 30 and rising Twitter buzz”). Alerts can be set for price movements, volume spikes, or custom indicators.
Education and Community
Thinkorswim offers a vast library of educational resources, including live webinars, video tutorials, and a “Daily Coaching” feature that provides real-time trading ideas. The platform also integrates social sentiment tools, pulling data from platforms like Twitter to gauge market mood.
Mobile Experience
The Thinkorswim mobile app is widely regarded as one of the best in the industry. It mirrors nearly all desktop features, including advanced charting, options analysis, and paper trading. Traders can execute complex orders or adjust positions from their phones without sacrificing functionality.
Who’s It For?
Thinkorswim is built for serious traders who need more than just a basic buy/sell interface. It’s ideal for:
Options traders managing multi-leg strategies.
Technical analysts rely on advanced charting and indicators.
Beginners who want to learn via paper trading and educational content.
Mobile-first traders need full functionality on smartphones.
Active Trader Pro vs. Thinkorswim
1. Features & Tools: What Platforms Suit Your Trading Style?
Active Trader Pro
Strengths: ATP excels in ETF and stock trading with tools like the ETF Screener, which filters funds by sector, expense ratio, and performance metrics. For example, you can screen for "low-volatility ETFs with dividends above 3%."
Order Execution: Offers Directed Trade, allowing users to route orders to specific exchanges (e.g., NYSE, NASDAQ) for better pricing—critical for high-frequency traders.
Options Strategy Builder: Simplifies multi-leg options trades (e.g., straddles, spreads) by visualizing risk/reward scenarios.
Real-Time Alerts: Customizable alerts for price movements, volume spikes, or news events.
Weaknesses: Limited technical indicators (25+ vs. TOS’s 100+). No backtesting or automated strategy tools.
Thinkorswim
Strengths Advanced Charting: Over 400 drawing tools (e.g., Fibonacci arcs, Gann fans) and 100+ indicators (e.g., Ichimoku Cloud, Market Profile). For example, you can overlay a 50-day EMA, Bollinger Bands, and volume profile on a single chart.
Options Analysis: The Probability Lab calculates the odds of an option expiring profitably while the Strategy Roller adjusts complex positions (e.g., rolling a covered call forward).
thinkScript: Lets users code custom indicators (e.g., a moving average crossover alert) or automated strategies.
Paper Trading: Practice with $100,000 in virtual funds via paperMoney®, replicating real-market conditions.
Weaknesses: Overkill for simple stock/ETF traders. Requires coding knowledge to unlock the full potential.
Verdict
ATP wins for ETF/stock traders who prioritize execution and research. TOS dominates for options traders and technical analysts needing depth and customization.
2. Usability: Which Platform Offers a Smoother Experience?
Active Trader Pro
Interface: Dated, cluttered layout with multiple windows (e.g., charts, order tickets, news) competing for screen space. Customizable, but requires effort to streamline.
Example: Setting up a conditional order involves navigating nested menus under "Trade Armor."
Learning Curve: Steep for beginners due to jargon-heavy tools (e.g., “Directed Trade,” “Basket Trading”). Limited tutorials compared to TOS.
Thinkorswim
Interface Highly modular: Users can create custom workspaces (e.g., a "Day Trading" tab with charts, Level II data, and a scanner).
Example: Drag-and-drop charts, resizable panels, and one-click access to options chains.
Learning Curve: Overwhelming for new users due to sheer options (e.g., thinkScript editor, 100+ indicators). Offset by live tutorials and a robust help center.
Verdict
ATP suits traders who prefer a no-nonsense, functional interface. TOS rewards users willing to invest time in customization and learning.
3. Mobile Experience: Which App Delivers?
Active Trader Pro Mobile
Features: Basic charting, watchlists, and order execution. Missing desktop tools like ETF Screener and Options Strategy Builder.
Usability: Functional but feels like a stripped-down version.
Thinkorswim Mobile
Features: Full desktop functionality: Advanced charts, options analysis, and paper trading. Example: Adjust an iron condor on your phone with the same profit/loss visualizations as the desktop.
Usability: Intuitive design with swipe gestures and customizable layouts.
Verdict
TOS is the clear winner for mobile-first traders.
4. Research & Education: Where Can You Learn More?

Example: “Fidelity Market Digest” provides daily macro insights.
Education: Limited to webinars and basic tutorials.
Thinkorswim

Education: The library includes 300+ videos, live trading rooms, and the “Education” tab with courses on technical analysis, options, and risk management.
Verdict
TOS wins for self-directed learners and traders who value real-time news/sentiment.
5. Unique Selling Points: What Sets Each Platform Apart?

Fidelity Ecosystem: smooth integration with Fidelity’s banking, IRA, and cash management tools.
Directed Trade: Exchange-specific order routing for better fills.
Thinkorswim

Which Should You Choose?
Decision Factor 1: What Do You Trade Most?
Stocks and ETFs: Active Trader Pro vs. Thinkorswim
If you trade many stocks and ETFs, you’ll want a platform optimized for speed and execution. Active Trader Pro (ATP) and Thinkorswim (TOS) can help you trade stocks, but each has different strengths. ATP excels in executing trades quickly and at the best prices.
Its Directed Trade routing and Fidelity’s $0 commissions make it ideal for high-frequency stock and ETF traders. For example, if you’re day trading SPDR sector ETFs, ATP’s ETF Screener and real-time Fidelity research (e.g., liquidity analysis) give you an edge.
The main limitation of ATP is that it lacks advanced charting for technical stock traders. Conversely, TOS is overkill for simple stock trading unless you need advanced charting or social sentiment tools. For instance, swing traders using Fibonacci retracements on AAPL would benefit from TOS’s 100+ indicators. The verdict? Use ATP for execution-focused stock and ETF traders. Use TOS for technical stock traders.
Decision Factor 2: Are You an Options Trader?
Options Trading: Active Trader Pro vs. Thinkorswim
If you are considering trade options, you should know the key differences between Active Trader Pro and Thinkorswim before deciding. ATP has some basic options capabilities, but it’s not designed for serious options traders. For example, you can build multi-leg strategies (e.g., covered calls, spreads) via the Options Strategy Builder, but there’s no probability analysis or strategy backtesting. You also can’t adjust complex positions (e.g., rolling an iron condor) with ATP.
On the other hand, TOS is loaded with tools for options trading. The Probability Lab visualizes the chance of profit for any options strategy. The Strategy Roller allows you to adjust multi-leg positions in one click, and thinkBack lets you backtest options strategies against historical data. For example, if you’re selling weekly SPX iron condors, TOS’s risk graphs and Greeks analysis are indispensable. The verdict? TOS is mandatory for serious options traders.
Decision Factor 3: How Technical Is Your Strategy?
Technical Analysis: Active Trader Pro vs Thinkorswim
If you’re a technical trader, you’ll want to choose the platform with the best charting capabilities to suit your strategies. Active Trader Pro and Thinkorswim have vastly different tools and approaches for charting. ATP has 25+ fundamental indicators (e.g., MACD, RSI) and simple drawing tools. It also has limited ability to compare multiple securities on a single chart. For example, ATP is suitable for traders using moving averages to track trends in QQQ.
Thinkorswim, on the other hand, has 100+ indicators (e.g., Ichimoku Cloud, Volume Profile) and 400+ drawing tools. You can also create custom scripts via thinkScript (e.g., code a custom divergence alert). For example, a futures trader analyzing Market Profile charts with volume-weighted averages needs TOS. The verdict? TOS is for technical analysts. ATP is for fundamental and ETF-focused traders.
Decision Factor 4: Are You a Mobile Trader?
Mobile Apps: Active Trader Pro vs. Thinkorswim
Fidelity and TD Ameritrade offer robust mobile apps for trading on the go. However, their offerings have different strengths depending on your trading style. Active Trader Pro Mobile features essential order execution, watchlists, and simple charts. The limitations are quickly apparent: No advanced tools (e.g., ETF Screener, Options Builder) exist on the mobile app.
For example, checking your Fidelity portfolio on the go? ATP mobile works. Thinkorswim Mobile, on the other hand, has complete options chains, advanced charts, and paper trading. For example, adjusting a strangle on NVDA during a commute is smooth. The verdict? TOS is the only choice for mobile-first traders.
Decision Factor 5: What’s Your Experience Level?
Beginner Traders: Active Trader Pro vs. Thinkorswim
If you’re a beginner options trader, TOS is the better choice. Its educational resources like paperMoney® and live tutorials will help you learn to trade options quickly. While ATP has a more straightforward interface for executing basic trades (buy/sell stocks and ETFs), it has limited educational content. The verdict? TOS for beginners willing to learn. ATP for beginners prioritizing simplicity.
Advanced Traders
TOS is the clear winner due to thinkScript, backtesting, and options tools.
Decision Factor 6: Are You Loyal to a Brokerage?
Platform Integration: Active Trader Pro vs Thinkorswim
If you have an existing brokerage account, sticking with that firm’s trading platform for smooth integration is usually best. For example, if you use Fidelity, you’ll find that ATP integrates with Fidelity’s banking, IRAs, and cash management tools. For instance, you can instantly settle stock sales into a Fidelity Cash Management Account. On the other hand, if you use TD Ameritrade or Schwab, you’ll find that TOS syncs with Schwab’s StreetSmart Edge for unified portfolio management. The verdict? Stick with your brokerage’s platform for smooth integration.
Decision-Making Checklist
Active Trader Pro vs. Thinkorswim: Which Trading Platform Is Right for You?
Answer these questions to choose: What’s your primary asset? Stocks/ETFs → ATP. Options → TOS. Do you need advanced charts/indicators? Yes → TOS. No → ATP. Is mobile trading critical? Yes → TOS. No → ATP. Are you a Fidelity/Schwab customer? Fidelity → ATP. Schwab → TOS. Do you want to practice risk-free? Yes → TOS (paperMoney®).
Edge Cases and Exceptions
Are There Any Exceptions?
Yes, there are a few edge cases to consider when choosing between Active Trader Pro and Thinkorswim.
Long-Term Investors: If you’re a long-term investor, ATP’s research tools (e.g., Fidelity’s Sector Scorecard) are better for macro trends.
Algorithmic Traders: TOS’s thinkScript allows basic automation (e.g., moving average crossovers).
International Traders: ATP only supports U.S. markets; TOS offers limited global trading.
