New paper available — Developing Robust Trading Systems, with Implications for Position Sizing and System Health

I have written a paper describing an original approach to evaluating the health of a trading system, and an original approach to determining position size based on system health.
The technique described:
• Is of practical significance to practitioners of active investing.
• Produces both faster account growth and lower risk when compared with a passive buy-and-hold strategy.
• Is illustrated using a fully disclosed trading system.

It can be found on the Resources page, in the Books category:

Why Traders Stop Trading

There is a new article in which I explain my thoughts on why traders stop trading systems. Among the points I make are:

  • It is important to monitor system health.
  • Drawdown is probably the most common reason traders stop trading a system.
  • Position size must be adjusted as system performance changes.
  • The correct position size of a system that is broken is zero.
