Let me ask a more basic question. If P123 is paying Yahoo to provide those charts, why hasn’t Yahoo given them new URLs for the charts?
How about stockcharts.com as a provider for the charts? They have a number of smaller “Candle Glance” charts, with a variety of parameters. The parameters could probably even be customized by individual.
