The 1-2-3 Rule for Confirming Trend Reversals

Summary

This article presents the 1-2-3 rule as a practical interpretation of Dow Theory’s trend-reversal logic, associated with Victor Sperandeo rather than a term used by Charles Dow himself. For an uptrend, it describes three signs: a trendline break, a rally that fails to make a new high, and a decline through the prior pullback low. The sequence may vary, but all three conditions are presented as necessary for confirmation.

The article recommends checking volume on the final break and using Dow Theory’s confirmation principle across related markets to reduce false signals. It suggests placing a stop near the key prior low and illustrates the pattern with Bitcoin’s 2021 market top. That example is illustrative, not a systematic test; the article gives no comparative results or quantified reliability. The rule remains a chart-based framework, so isolated signals may fail and should be treated cautiously.

Key ideas

• The 1-2-3 rule translates trend reversal into three observable price conditions.
• For an uptrend, the sequence involves a trendline break, a failed rally, and a break below a prior pullback low.
• The conditions may occur in different orders, but the article requires all three for confirmation.
• Volume expansion and confirmation across related markets are proposed as ways to assess a break.
• The article presents a Bitcoin example but does not provide systematic evidence of the rule’s reliability.
