Every now and then I see a post with a chart with this. What services provide bullish %, and how is the data computed?
StockCharts.com displays Bullish % Indicator http://www.stockcharts.com/education/Resources/Glossary/bullishPercent.html and you can also do a good search via Google at http://www.google.com/search?hl=en&q=Bullish+Percent+Indicator&btnG=Google+Search It brings up tons of info on this indicator.
