Sort stocks by percent change or my holdings change

Vanguard-Sortfix.js

/*
  Generally, don't run random JS in your browser console, especially on financial sites, but here we are
  By default this sorts by Percent Change. If you uncomment the next line it sorts by myDelta (price x your shares)
  Caveats:
  - I'm not affiliated with Vanguard or any licensed financial advisor or tax preparer. I don't have a clue what's going on with your finances.
  - The script assumes you did NOT trade today; it uses today's change and current shares
  - Delta-sort does not handle penny stocks as well because the UI says 0.01 and we reverse-engineer from current balance
