Computerization
In the US, Chartcraft used an IBM S/360 in the 1960s to produce point and figure charts.
Point and Figure charts were automated in the UK in the early 1980s by the Indexia company run by Jeremy Du Plessis. This automation increased the popularity and usage of point and figure charts because hundreds of charts could be viewed and altered quickly and easily. At the same time a method of log scaling point and figure charts was devised, where the value of the Xs and Os was set to a percentage rather than a price. This allowed the sensitivity of Point and Figure charts to remain constant no matter what the price level.
Kaufman, in New Trading Systems and Methods, 2005, documents research he and Kermit Zeig performed over many years computerizing point and figure charting. LeBeau and Lucas also developed computerized point and figure charts in Technical Traders Guide to Computer Analysis of the Futures Markets.
