Measurement of how accurate is the forecast information.
I pay a cryptocurrency price forecast service, but they don't have any API, so they show the information only on their website. I want to copy and paste the forecast information of each cryptocurrency in an app every day in order to compare it with the daily real price and measure graphical and numerically how accurate is the information their selling to me.
The app has to have the capability of:
--Add manually any cryptocurrency symbol then manually upload the daily information making copy in my provider and paste into the app.
--Must compare the information uploaded with the daily price of that cryptocurrency.
--The newly uploaded information has to update the former information.
--The live price should get it via any API.
--With only one click the app should show me a graphic and numerical report separately but on the same page.
--The graphic has two axes, price and time, then should show three historic things according to the data uploaded. (see photo example)
1-The line of the real price.
2-The line of the forecast price.
3-The forecast price range.
--The numerical report should show me a list with the following columns.
1-Date.
2-Daily Percent o accuracy (more close to zero, mean better accuracy of the forecast).
3- Up-today of total accuracy percent average ( more close to zero, mean better accuracy of the average forecast).
--The app should have only two interphases.
1-The front page that let me create a new Cryptocurrency symbol and show me the number that is the overall accuracy average.
2-The one with the list of symbols created and each symbol in the list has three buttons.
a)-One button that lets me upload new information for that specific symbol.
b)- The one who let me see the reports.
c)-The one to delete the symbol and their information.
