Evaluating Averaging Strategies Through Drawdowns and Profit Distributions

Summary

The article examines rebuy, or averaging, systems that add trades against price movement in hopes of closing each cycle at a profit. It argues that a steadily rising balance can hide an unfinished losing cycle, whose drawdown may continue for an unbounded period relative to the available account capital. A good-looking historical curve therefore does not establish that the method is safe or reliably profitable.

The author emphasizes that expectancy estimates from finite samples apply only to the periods and conditions observed. For averaging strategies, the shape and distribution of cycle outcomes matter, and a single backtest is not enough to assess survival or profitability. The discussion proposes using mathematical comparisons of distributions, longer test segments, and diversification across strategies to refine evaluation. The excerpt is incomplete, so it does not provide the full derivations or enough detail to reproduce the proposed procedures. Its broad claims about longer tests and diversified systems producing more attractive curves should be treated as theoretical arguments pending the applied validation promised in a later article.

Key ideas

• Averaging systems can show regular gains while carrying a large loss in an unfinished cycle.
• Finite-sample expectancy describes the tested conditions and cannot establish future profitability on its own.
• Drawdown duration and severity may grow with the test horizon, making deposit and money management central to survival.
• The author proposes analyzing outcome distributions and diversification to improve assessment of averaging systems.
• The excerpt presents its conclusions as theory and leaves full derivations and applied validation for later work.
