Stefan and Bob. Ascending Triangles. Stefan, your presentation of the charts with the scans, in post #212, is very useful. Here's a chart that I've created based on an example in John Murphy's book, Technical Analysis of the Financial Markets. <img src=http://stockcharts.com/def/servlet/SharpChartv05.ServletDriver?chart=%24TRAN%2Cuu%5Bh%2Ca%5Ddaolynay%5Bd19970702%2C19980218%5D%5Bp%5D%5Bi%5D%5BJ7047713%2CY%5D> I think this example demonstrates just how difficult it could be to design a scan to find similar Ascending Triangles. The triangle formed over a three month period, in Daily data. The flat top was almost, but not exactly flat, so using an "=" sign wouldn't quite work, but using "=>" might not produce the correct results either. Any ideas for a scan that would locate this sort of pattern? Cush
