Interactive Brokers have a long list of recognitions, such as top-rated for advanced options traders, advanced traders, advanced day traders, charting for day trading, day trading in general, fractional share trading, low margin rates, and ETF research. We think TD is the best choice for international trading and non-U.S. investors but it isn’t the ideal choice for futures trading.

Interactive Brokers and TD Ameritrade offer several amenities to their users and customers. These companies provide access to watchlists, streaming quotes, research, news, calendars, fundamentals, technical/charting analysis, market updates, and daily commentary. Their trading platforms are available in mobile, desktop, and web versions, making them accessible almost anywhere.

The flagship program of TD is thinkorswim, a sophisticated tool packed with features comparable to IBKR’s Trader Workstation. They also have more simple web platform than IBKR. Moreover, it has two helpful and powerful apps – one mirroring thinkorswim and one mirroring the web platform.

Interactive Brokers (IBKR) has two new platforms, which we have below.

  • GlobalTrader – It is an application supporting cryptocurrency trading. It aids traders and investors in international market opportunities.
  • Impact Mobile – An application designed to help investors whose interests are around environmental, social, & governance (ESG). These investors are keen to invest across the 90 international markets.

In addition to these two popular new platforms, IBKR has Trader Workstation, IBKR Mobile, and Client Portal.

TD Ameritrade has a smoother account opening process than IBKR, making it an advantage for customers wanting to open and fund an account via mobile or computer. It owes this advantage to the broker’s tenure on the retail side. 

On the other hand, IBKR’s accounting opening process is more tedious and requires more time. IBKR has several offerings to its customers, making it an overwhelming experience for amateur users. Although they have already improved and streamlined this process, there is still more room for improvement.

Paradigm Futures provides 24-hour access to trade on your mobile phone or desktop if you have internet access. Transactions between 7:30 AM to 7:00 PM Central Standard Time (CST) do not have additional charges, while transactions outside this timeframe have a USD 3.00/filled contract night desk fee.

We give the edge to TD Ameritrade in the usability category because of the simple and smooth account opening processing. Moreover, their platform is more intuitive to use overall, partially because they have fewer offerings. 

Trade Experience: Desktop vs. Mobile

We can divide trade experience further into two categories – desktop and mobile.

Desktop Experience

Interactive Brokers, TD Ameritrade, and Paradigm Futures have working desktop platforms. It has multiple features and good functionality, the qualities an investor would expect from a brokerage platform.

These platforms provide customization to the user, including but not limited to the following:

  • Route orders
  • Setup custom defaults
  • Group orders
  • Select tax lots
  • Create specific trade orders to use as criteria
  • Percent loss or gain
  • Specific data pieces

Sophisticated and advanced traders and investors will find the experience satisfying. However, we noticed IBKR is evolving faster than Paradigm Futures and TDA because it continues to add markets, features, and assets to its platform. On the other hand, TDA is focusing on the final integration phase with Schwab as part of its acquisition.

All three brokers have excellent platforms, with functionalities surpassing their competition. Although TDA has a more modern look and feels than the other two, we rate this section a tie. IBKR is a more promising option for accessing more asset classes and international markets. 

Mobile Experience

TD Ameritrade offers two options for mobile users – the TD America Mobile app for a simple user interface and the thinkorswim app for more active and sophisticated users. IBKR offers IBKR Mobile, an excellent application for delivering organization multi-exchange, multi-country, and product offerings in a single platform. IBKR also has GlobalTrader, an application with a streamlined experience designed for newer investors. Paradigm Futures also features a mobile application that is simple to use.

IBKR Mobile, Paradigm Futures, and thinkorswim app mostly replicate the workstations, with pages for watchlists, portfolios, and the ability to book order tickets. These applications also support several order types, including options strategy and conditional orders. Options strategies are either calendar and vertical spreads, condors using dropdowns, and butterflies. It is worth noting IBKR Mobile does not support chart drawings. However, it shows the order to cancel or change.

On the other hand, the drawing tools in TDA’s mobile app are accessible. The watchlist also syncs between mobile and desktop applications.

One notable limitation of thinkorswim is the lack of support for fixed-income trading. However, the said app lets users simultaneously log onto the mobile and desktop versions. On the other hand, IBKR and Paradigm Futures only allows users to log onto one platform at an instance.

With everything said, we think TDA’s thinkorswim app is the best choice for the mobile experience. It is easy to use and does an excellent job of copying the desktop experience. 

Range of Offerings

Interactive Brokers, TD Ameritrade, and Paradigm Futures offer a wide set of asset types in the trading platform. These include the following typical ones:

  • Long and short ETFs and stocks
  • Mutual funds
  • OTCBB issues
  • Futures/Commodities
  • Fixed income
  • CDs
  • Foreign exchanges
  • Single and multi-leg options

International exchanges between brokers have a huge gap, as TDA provides access to one international exchange, while IBKR supports 95 international exchanges and 200 countries.

TDA offers 70 pairs in 19 currencies, while IBKR offers 100 pairs in 24 currencies in foreign currency trading.

Although both brokers have distinct offerings, the clear winner for this section is IBKR. The sheer number of markets and products tradeable on IBKR’s platform is unrivaled by any other broker. 

Order Types

TD Ameritrade supports the typical order types, such as trailing stop orders, limit, market, and stop-limit. Its platform allows conditional orders, including but not limited to order-triggers-two (OTT) and one-cancels-the-other (OCO). It also supports late entry on stage orders, allowing investors to select the tax lot when placing orders. 

On the other hand, Interactive Brokers support the same order types but go the extra mile by supporting more than 100 algorithms and order types on the TWS Pro platform. It allows users to combine OCO orders and logical conditions. It leverages margin cushion, volume, price, time, percent change, daily P&L, and other significant variables to create customized orders. The lite version of IBKR supports 25 different order types, including the ability to use the custom algorithm.

Paradigm Future has a similar feature set to TDA. 

IBKR holds a clear advantage because it goes much further. 

Trading Technology

The excellent technology behind Paradigm Futures, TDA, and IBKR enables a smooth trading experience. These brokers can route and stage orders and allow automated trading strategies. 

IBKR and TDA have portfolio margining and securities lending, a feature unavailable to Paradigm Futures.

With everything said, TDA has an advantage over Paradigm Futures and IBKR for trading technology.

Customer Service

All three brokers provide top-notch customer service to their clients with options in support, including live chat, phone, email, and a live broker (for a fee). The Frequently Asked Questions (FAQ) section is also helpful for quick assistance. Interactive Brokers highly recommend interacting with the chatbot first before trying other options. IBKR is also less efficient in handling calls than Paradigm Futures and TDA.

We give this point to TDA for overall customer service satisfaction in 2022. However, Paradigm Futures is close behind, having positive reviews from a large percentage of its customers.


Paradigm Futures, TDA, and IBKR meet industry standards for security. Neither has experienced a data outage or breach in the past year. They all offer biometric recognition and two-factor authentication for a more secure login experience. Security is likely the only category they are all a tie.
