My name is Jaime Sommer, I am brazilian, I am a retired software developer living in Israel. I developed an app(for desktop)/apk(for android) in order to offer POINT & FIGURE Chart. At the moment I have only Bovespa B3 in my app. I would like to put also American SE in it. I saw you offer csv file with historical series, but at a cost that I can`t support. As this graphic is not very popular, even being the best of all, I propose some kind of partnership in order to reach this goal (maybe you could consider offering it in your site...) . If You are interested, I can provide a video of the app. Thank you for your attention.
