Introducing Merlin

A quantitative strategy for trading stocks and ETFs

Then you’re in the right place!

Allow Merlin, a quantitative strategy developed by the Trade Risk, to guide you through the chaos of markets and help you profitably trade individual stocks and ETFs.

Trade aggressively in bull markets and stay defensive in bear markets

Merlin's real magic is in its unique ability to toggle the strategy from its aggressive growth state into a more defensive mode during unfavorable market conditions.

Choose to follow a more aggressive Margin portfolio, which allocates up to 150% invested (50% margin), or a more conservative traditional IRA portfolio, which uses no leverage.

Here are the performance results for the IRA and Margin portfolios compared to a 60/40 stocks and bonds portfolio.

How Merlin works

Merlin is a long-only algorithm that buys retracements in momentum stocks during healthy market environments. It trades individual stocks, equity ETFs, and all signals are generated using daily closing prices.

That means no intraday screen watching is required and all orders can be placed after the market closes. 

Trade confidently with a systematic, evidence-based strategy

Merlin is based on the time-tested, academically approved factors of mean reversion, momentum, and growth, and its execution refined from over a decade of bar-by-bar price action analysis and live trading by Evan Medeiros.

The strategy has been backtested and validated across thousands of stocks and ETFs with careful considerations not to data mine or overfit.

Frequently Asked Questions

What is a quantitative strategy? What are the benefits?

A quantitative strategy means all of the buy and sell decisions are based strictly on mathematical computations and probabilities. There’s no gut feel or subjective analysis – the system contains all of the rules to make the best decisions possible.

There are many benefits of quantitative strategies:

  • 100% discipline, the system always executes flawlessly
  • No emotional biases
  • The strategy has been tested and verified over past market environments
  • The strategy is easily measurable and can be enhanced over time

What makes Merlin extra special is that it was built by a trader first. Evan’s market observations and live trading for over a decade are at the core of Merlin’s decision making process. That means Merlin is not just applying random and impossible to explain mathematical theory, instead, it’s a simple system based on how markets really work.

How do I interpret the performance measurements above?

We pride ourselves on transparency and we want to be sure you have all of the information possible to properly evaluate the Merlin trading system. This is why we give a detailed view of performance measurements so you can make an informed decision about the strategy. 

Some of these terms get pretty complicated with in-depth equations which is why we created a Trading System Performance Metrics glossary to share all of the details behind everything like: Sharpe Ratio, MAR, Correlations, etc. If you're confused about anything you see in the table above, or if you simply just want to learn, head on over to the glossary

How many trades can we expect a week?

Merlin has averaged about 1 to 2 trades per week over the past decade, however, the actual distribution of trades tends to be much lumpier. Instead of consistently trading every week the strategy tends to go through busy periods followed by quiet periods.

During busy periods you might get a full month of five or more new signals each week. What follows after a busy period like that is usually a month or two of quiet activity as the trades play themselves out. Of course, Merlin's activity is largely dictated by the overall market environment so the healthier things are the more likely it is that Merlin is going to be active. 

What is the minimum account size for Merlin?

Merlin is a professional trading strategy that focuses on producing strong risk-adjusted returns. It’s designed to scale and handle large account sizes. 

Account minimums are a personal decision and will vary greatly from trader to trader depending on your circumstances, goals, and risk tolerance. Here are some general guidelines to get the most out of the Merlin trading service. 

  • Minimum account size: $25,000
  • Recommended account size: $50,000+

What subscribers are saying

"So far three months in, I am very satisfied with the service. I track things closely and the returns in my Trade Risk (TR) account are significantly better than when I trade on my own in other accounts.  I have been a trader for several years, but unfortunately, I never found the consistency that I needed. TR has really made me a happy trader!"

David D.

"Merlin has been on fire! Wow! Great and courteous support by Evan. Texts are timely and clear. A true bargain. Highly recommended!"

Jim B.

"Your Merlin system is amazing, simple to understand, and on a fundamental level, it completely makes sense to any seasoned trader. I have seen much success with your system and it looks like Merlin is here to stay in my playbook!"
