Using Drawdown, Holding Time, and Profit/Loss Ratio to Assess Traders

Summary

The article warns against choosing copy-trading accounts solely by headline win rate or return on investment. It argues that unrealized losing positions and repeated averaging down can make a record look successful while hiding substantial exposure and eventual liquidation risk. As an alternative, it names three measures to inspect: maximum drawdown, average holding time, and the ratio of average profits to average losses.

Maximum drawdown is briefly defined as the largest percentage decline in account equity from a prior peak to a subsequent low. The article frames holding time as a clue to changes in trading style and the profit/loss ratio as a measure relevant to long-term expectancy, but the provided text gives no definitions, calculations, thresholds, examples, or supporting data for those two measures. These indicators can help prompt further review, but the piece does not explain how to combine them or account for leverage, risk per trade, open positions, or changing market conditions. It is a short checklist, not a validated trader-ranking method.

Key ideas

• A high win rate can conceal large unrealized losses or repeated averaging down.
• Maximum drawdown measures the largest equity decline from a previous peak to a later low.
• Average holding time may help reveal whether a trader’s behavior or style has changed.
• The profit/loss ratio should be considered alongside win rate when assessing trading outcomes.
• The article names useful review metrics but provides no calculation examples or validated selection thresholds.
