Why Daily Candles Can Reveal Backtest Volatility Hidden by Smooth Curves
Summary
The document raises a visualization concern: a smooth backtest equity curve may conceal the size of fluctuations a strategy could experience in practice. It proposes displaying results as daily candles, including each day’s high and low, so readers can see movements within the day as well as the sequence of daily outcomes.
The note offers no implementation method, example chart, or measured comparison. Its useful point is that a single smoothed curve can make a strategy’s path appear easier to tolerate than it might be when interim adverse moves are visible. Daily bars could help with visual inspection of volatility, but they do not by themselves establish realistic execution, capture every intraday path, or replace other risk analysis. The author describes the request as nonessential and says the strategy already has risk controls.
Key ideas
- A smooth backtest curve can obscure fluctuations that matter to a trader’s ability to tolerate losses.
- Daily candlesticks can show each day’s range through their highs and lows.
- A more detailed chart may improve visual understanding of backtest variability.
- The document presents a visualization request, not evidence that daily candles improve strategy performance or risk control.
