DAS Trader is by far the most robust trading platform out there.  I’ve used this tool every day trading since 2003. I’ve compared it to many others out there and it always stands out as the fastest! The team has been helpful and listen to any and all suggestions to continually make this software better! Great team, great people and highly recommend this to ANY serious traders! (Not to mention they have by far the most incredible mobile app on the planet)

Justin Ritchie

I have been pleased with the online trading platform and very pleased with the customer service I’ve received so far.

Stefanie Kammerman

Founder and Managing Director, The Stock Whisperer Trading Company

Over the past 20 years I tried and tested numerous trading platforms and I have to say that the DAS Trader Pro is by far the best platform. What I like most about this platform beside being simple to use, is the ease of zooming in and out of my charts along with the drawing tools that help me find the best support and resistance levels. I share my screen all day teaching thousands of students how to day trade and swing trade using this platform at www.thestockwhisperer.com Other great features include the top 20 list, the ECN book and the multiple time and sales windows. I highly recommend this product.

Chadd Hessing

President and CEO, Cobra Trading, Inc.

We offer DAS for both our Cobra Trading and Venom Trading clients. The platform is great for beginners and veterans alike. It offers tremendous value and ease of use, while offering a host of features such as advanced charting, mobile trading and a short locate monitor window.

Jiyoon L.

I just received assistance from DAS Support on an issue that was efficiently handled.  I also had my DAS platform and hotkeys explained and organized for me. I really was taken away by the help and service I had to write you an email.   – Korea

Pete D.

I have used DAS Trader for many years now and have referred many of my colleagues to your trading platform.  Yes your product is of quality and does what we expect with trading but the MOST important aspect of a product is it’s support system.  You’re staff that we rely on when we have questions, technical issues or problems.  There are a ton of trading platforms on the market out there but as a financial analyst for a large institution I ALWAYS recommend your product!  -Denver, CO.

Adil K.

I just coordinated with the DAS support team and am impressed to see how they treat their customers, not just as a customer, but helping them out as their own family members.  – Punjab, Pakistan.

Jussi T.

I must say that when i was in need of help, one of your technical advisers came through and put in the time to sort all of my issues out.  I had some computer issues and platform issues i needed looking at.  I did not expect this kind of service, but am really happy that i reached out to you. Thank you for the excellent service and a big thanks to the DAS support team for helping me out!  – Forsby, Sweden.

Amin A.

It has been over 5 weeks that I am using DAS Pro, and I must say I had the best customer service ever for services I have ever purchased or subscribed.  I sent a lot of questions (many of them dumb) and problems to Support team, and less than 5 min I was always had my problems solved/answers in my inbox. Great success in any product/services is when the customer does not feel stupid or ashamed of contacting support team.  This is my case.  -Vancouver, Canada
