Allow me to introduce myself. I am Mark David Johnson, also known as OpusTrader on the TradeStation Forum and Wiki. I have been a full time Trader and EasyLanguage Programmer for over 10 years. I have been involved in programming for over 31 years and involved in trading for over 21 years.

I have a wide range of EasyLanguage programming skills and experience covering Forex, Futures, and Stock trading.

Allow me to introduce our software engineering and mathematics specialist. Mr. Robertson has been a long term fundamental investor, swing trading, and day trader within the equities and options markets for over 10 years. His specialty is risk management, long term special situation investing, and utilizing mathematics to facilitate everything from long term investing to scalping stocks. In 2005 he started a mentorship under the former risk manager and lead trader for Tudor Jones Capital, one of the most successful, if not the most successful hedge fund of the common era. To this day, Mr. Robertson still trains under his mentor.

His educational background started at the University of Miami for a B.S. in Mathematics and Harvard University for an M.A. in Software Engineering. He graduated with a B.S. in Decision Systems and Mathematics from Carnegie Mellon. He graduated in the top 3% of his class with Phi Beta Kappa honors. In his senior year, Mr. Robertson was given the opportunity to be an assistant teacher to Junior students majoring in Computer Science and Decision Systems. He held his own class in teaching proper Object Oriented techniques using Microsoft's visual basic and C++.

At CMU, his advisor and mentor was the late Dr. Herbert Simon, often considered one of the most prolific scientist and economists of the 20th century. He was awarded the Noble Laureate, Medal of Science recipient, and the Turing award, and is considered the father of artificial intelligence.

Mr. Robertson has written and designed software for such industries as the airlines, automotive, health, semiconductors, and the stock market. Upon graduation from Carnegie Mellon in 1996, until 2006, he worked with such companies as Intel, Ford, Microsoft, Oracle, SUN Microsystems and numerous other fortune 500 companies.

"I had just been trading for 8 months when I depleted my first whole account. The rule that all brokers know is that within 3 to 9 months all beginning traders get blown up is a fact no matter how intelligent the beginning trader thinks he is. I was determined after a loss equating to a Yale or Harvard tuition, to trade correctly and learn from the best there is. It didn't take me much time to discover Customized Trading.

The light bulb clicked and I decided to tackle the science, everything any trader whether beginner, advanced or even master can and will find an edge in Customized Trading's tools and techniques.

I would go as far to say that they have the best most advanced high-tech trading tools and strategies that exist on earth. There are no shortcuts in professional trading but with Customized Trading (CT) traders will have a genuine chance at success if they put their mind to it.

Not only you get a variety of powerful and simple tools but the lessons explaining the how and the why which will elude most traders present and upcoming beginners or veterans.

I firmly believe that CT is the 1st and only stop to professional trading with the plethora and richness of all kinds of materials it offers. Moreover, CT goes further and has handled all my complex programming requests flawlessly, there is no other high-level professional trader, super coach or master programmer like Mark David Johnson. I have the privilege to have been indoctrinated in the correct fundamentals and principles that still hold true since the golden era of technical analysis on Wall Street.

I highly and strongly urge anyone looking to find his edge in the speculative markets to start with CT and go all the way as the marathon is long but doable. Having CT on my side shaved off perhaps decades of the learning curve and they even made my tasks easier by creating their custom indicators and further customising them to meet my exact needs and trading styles. As such, I have never seen something as powerful and efficient as CT. it's a university for professional traders that offers everything from tools to bespoke work to trading lessons. For success in this modern day and age, I would only chose one website for all my needs and education as everything is technology oriented, technically sound and true, and powerfully computer-assisted making several of the trader's jobs easier and comfortable".

"I have used Mark David Johnson's EasyLanguage programming services for many different projects over the last few years and I am always very impressed with his expertise and knowledge and also the quick and professional manner he works.

He is very easy to work with and is logical in both a trader's mind and a programmer's mind.

I have always been happy with his completed projects and I have learnt a lot from his work - I will continue to use his expertise as I move forward in this EasyLanguage world."
Michael Hale from Howick, New Zealand


"As we have worked with each other over the past several months I have become increasingly impressed with your market knowledge and related products. Your product line is adaptable for system traders, as well as discretionary trading; plus you have products for every market mode (trending, consolidation, range bound). I particularly like the Multiple Time Frame (MTF) work and your visual presentation of the indicator. The MTF indicator is very unique and applicable to many aspects within the market.

If someone were to ask me what one area would you recommend the most?, I would, without hesitation, say it is the webinar training / coaching. Mark, you have the ability to teach as well as program. This is a talent rarely seen. I have found you to be well spoken, patient, and very insightful."
William L Cargill from Virginia, USA


"I have been working with Customized Trading over four months now. Their indicators are far superior to the competition. I have enjoyed very reasonable custom programming by purchasing the 'Scalper Day Trading System'. They provide not only the products you need, but the support to improve your implementation for using this advanced programming. The coaching webinars are extremely helpful, I highly recommend taking advantage of the talent and experience you will glean from. I am always excited to learn about any new product or technique they offer. CustomizedTrading is a company you can trust, that cares about you."
Paul Graumann from Colorado, USA
