The Crossley Bird ID Guide is, to my mind, a good segway to Abe Cofnas’s Sentiment Indicators: Renko, Price Break, Kagi, Point and Figure: What They Are and How to Use Them to Trade (Bloomberg Press, 2010). Cofnas contends that the best way to use the chart types he describes is “in tandem with candlesticks” because “using all five charting methods together [will] generate enhanced confirmations of key price points.” (p. 8)
Each chart type has a “best use” in trading. The price break chart is best at detecting the beginning of a trend, projecting reversal points, and confirming cycle turning points. The Renko chart detects “micro changes in sentiment and momentum.” The point and figure chart shows support and resistance lines, projects breakout ranges, and balances bulls and bears. And the Kagi chart is good at timing the turnover of sentiment. (p. 7) Let’s look very briefly at the first two types of charts here.
Price break charts, available on Bloomberg Professional workstations but easily programmable on other platforms (Cofnas spells out the construction logic), are often known as three-line break charts, although there’s nothing sacrosanct about the number three. They could be set up as six-line break charts just as easily. The idea is that “a series of black columns will be followed by a white column if the high of the previous [x-number of] black columns is broken by the new price. … A black column is added if the low of the previous [x-number of] white columns is broken.” (p. 23)
Cofnas explains how to understand the strength of price movement using price break charts and describes trading strategies (focusing on entries). He also looks at combining cycle analysis with price break charts, describes multiple market applications of price break charts, and explores the use of price break charts in option trading. (more…)
