Three Line Break Charts: Construction, Filters, and Trend Signals

Summary

The article explains how to construct a Three Line Break chart from closing prices without using equal time intervals to determine each new line. A line extends the current direction when price exceeds the prior extreme; a reversal requires price to cross a threshold based on recent lines. The classic method uses one selected price series, while the described modified version combines open, high, low, and close data, with synchronization rules for missing values. The indicator also supports a minimum movement filter, configurable reversal length, period color changes, and a moving average aligned to the chart data.

The author discusses using the chart for trend analysis, including moving average conditions as possible buy or sell cues, and notes that candlestick patterns can also be examined on the transformed display. The examples are illustrative rather than a rigorous performance study. The author favors longer-term use and cautions that signals may be infrequent and drawdowns substantial; the suggested approaches need further development and validation.

Key ideas

• Three Line Break charts add lines when price extends an extreme and require a multi-line threshold for reversals.
• The chart filters minor price fluctuations because elapsed time does not determine when a new line forms.
• The indicator offers classic and modified construction using selected price fields and synchronization options.
• A minimum movement setting and moving average can be used as additional filters for chart analysis.
• The author recommends longer-term use and identifies infrequent signals and possible drawdowns as limitations.
