• Input: date range
• Output:

1. longest bearish (downward) trend
2. date with highest trading volume
3. Dates for optimal buy / sell

Publish the app somewhere on the web. Shouldn't be too hard as Flutter web apps are self-contained JS thingies with static files. This is not strictly necessary but I'm guessing it might be beneficial.

Alternative B would be an Android app, but that might be a bit more complicated. Could be a nice extra, though.

• Progress indicator
• I18n of date picker
• Error handling
• Currency display prettification
• Split off number crunching from scraper
• Make layout adapt better to huge windows (= make it narrower)
• Maybe a price point class or such to bundle DateTime and value

The date picker goes "mm/dd/yyyy" in my browser. Should probably look into that side of things.

Looks like finding optimal trade dates (numberCruncher.getOptimalTradeDates) doesn't quite work. A range from 2021-12-08 to 2021-12-17 shows a 3 day bearish period but "trading in this period is not advisable". Must rethink algorithm.

• Need to get the dates from the UI (see #1 )
• Pull data from CoinGecko (https://www.coingecko.com/en/api/documentation)
• Do the necessary operations (check for bearish trend, highest volume, optimal buy/sell)
• Push the answers to the UI.
