The "Whitelist" code is working as is the download of ARK's positions. The next step is to clean up the list. There are a number that are not valid ticker symbols, for example:

[1] => 4477 <--- numbers
[16] => ARCT UQ <--- space
[82] => NTDOY <--- 5 letters, valid but...

These are easy to get rid of with code, most won't have Yahoo price data anyway. Suggestions?
