Tradier is a high-tech brokerage designed for active traders

The company offers two pricing tiers: low-cost options trading for $0.35 per contract and an all-inclusive trading package for $30. Tradier also features an easy way to build brokerage applications, a way to monetize client referrals, and API connections to many top financial technology companies, like QuantConnect.
The integration between Trader and QuantConnect is an intuitive one, as both companies were built by developers and quants for others involved in the math, data science, and financial technology sectors.

Your entire team consistently demonstrate an obvious commitment to helping people both understand how your product works and keeping them happy by tempering frustrations – and this is nothing short of World Class support. Sincerely, I think QuantConnect is one of the most important financial tools in industry.

I love QuantConnect for all of the features - can code my algorithms in C#, my favorite language, the bootcamp series got me up and running in no time, the online documentation makes it so easy to develop, the way QC consolidates ticks, trade and quote bars of different periods into a single event, OnData, simplifies things and my favorite: I can run Lean on my desktop and use all of the features of Visual Studio.

I really appreciate the team's work on QuantConnect, it's a stunning masterpiece. I was a option market maker. I'm using Lean as my core backtesting engine, I think it's super powerful to support both research, backtesting and live-trading, and I believe it would be stronger in future.

Multiple students have singled out their time on QC as the single most educational experience of their undergraduate career. Some even said "most fun"! All said it was difficult which should be taken as a compliment because "fun"/difficulty is the holy grail of student reviews.

The platform is very easy for team members to collaborate on the code development simultaneously. Very easy to implement new algorithms with Interactive Brokers.
