An aggregating portfolio tracker. This tracker will be able to fetch product id's and prices from DeGiro, Binance and StockX. Consequently, this data can be stored, for example in a .csv file for personal bookkeeping.
Implement a similar .xlsx writing method as is implemented for stocks but for the cryptocurrency wallet. Now, the script returns the EUR value of the held cryptocurrencies (with the exception of locked staking products) and they have to be processed into the .xlsx manually.
Right now, the StockX portfolio tracker takes the 10 most recent prices of a shoe in any size to calculate the value of the shoe. This should be changed to only take the prices of the shoe with the same size as in the inventory. Note that there are also items that have no size or are one-size only that still need to have their value calculated as well.
Scrape the StockX website for the latest sale prices of shoe in inventory (.xlsx file). Take the average of the sold prices in one week as an indication for the price of a given shoe.
Binance does not as of yet support fetching locked staking products. Keep an eye on Binance API developments and implement when possible. Otherwise finding another workaround would be fine as well.
