Unfortunately, there seem to be a countless number of ways to evaluate a trading system. Thankfully, there is a whole niche of books devoted to trading system development and evaluation. I have made a list of the books and will begin reading them this year with the goal of refining my personal system evaluation procedures and development processes. I recently purchased "Systems Trading for Spread Betting: An End-To-End Guide for Developing Spread Betting Systems" by Gary Ford. This seems like a good starter book because it walks through the fundamental steps of creating and evaluating a trading system. Currently, I am not interested in spread betting, but I am always looking to learn something new. The real bonus is that the author uses NinjaTrader for the system development and evaluation, which should significantly improve my platform skills.
I will eventually develop an entire post/plan for my evaluation procedures and add it to the side bar, but for now this is more of a kick-off post to highlight the various areas of system evaluation. From what I have seen, below is a list of topics that my system evaluation procedure should address:
- Time frame analysis (ticks, minutes, hours, days, etc.)
- Day trading time analysis (what hours during the trading session)
- Contributions of each aspect of the indicator/strategy
- Entries and Exits
- Filters for volume and volatility
- Backtesting
- Risk management and position sizing
- Parameter optimization
- Walk Forward optimization
- Monte Carlo simulation
- Bootstrap analysis
- Stochastic process control theory analysis
- Simulated strategy trading
- Live trading
This is just an initial list of topics to be investigated. Hopefully, once I have read a few books on the subject I will have the basic steps of my procedure in place and I can begin evaluating systems on this website. My initial goal would be to evaluate at least one indicator/strategy a week. The primary goal would be to familiarize myself with each procedural component to better understand its strengths and weaknesses. Once that is accomplished, I can then focus on determining the true merits of a sample trading system.
