Could anyone give advice to me on how to make a share portfolio manager app?

hey friends, I am thinking of making an app that can help you track the value of your share assets, besides keeping account of your dividends and being able to tell you if you are profiting or making a loss by holding that stock. Could somebody give me advice on how to build such an app? I will need to take data from a website that has the price of shares right?

Have you checked out the web sites of investment houses like

Black Rock, Fidelity, and Vanguard?

They do that for you, within the bounds of your holdings

at each site.

Unfortunately I don't use those websites. My website doesn't have one that takes into account dividends too.

Perhaps this app in the gallery will help you

@Tim     Unfortunately the Amazon finance api has changed dramatically since 2015.   User's have to obtain an api key and the service is no longer free; the service is through subscription.  The change occurred sometime in 2018.  The api link in this example you pointed to no longer works.  Try this... this indicates Amazon is not free but does offer a free usage tier https://blog.rapidapi.com/how-to-use-the-yahoo-finance-api/ 

@ Joe  This app no longer works with the Amazon financial api.   You might build something similar using one of these apis https://www.google.com/search?q=stock+api&oq=stock+api&aqs=chrome..69i57.139321j0j4&sourceid=chrome&ie=UTF-8   or sign up for an Amazon developer account, there is a free tier (see above link)

Good luck.

@ Steve

Was about: "how to make a share portfolio manager app"

@Tim ..thought anyone expecting the app that is in that link would work would be disappointed.  The app does not work.  The example depends on an old Amazon financial api. and is the old api specific  :)

Edit... time repaired.

Old Father Time agrees :)
