### Comment:
For what purpose? If I put in $5k buying at whatever price, and get $10k out at whatever price... It's exactly the same thing. Do they charge a different percentage based on how much you make on a specific trade??

### REPLY:
You can play with the numbers to pick the year you take gains in. If you make 1k two years in a row, you pay less tax than if you make 100k this year (pay maybe 40k in tax) and lose 98k next year (get no tax back). 
  
 Not an accountant, if someone else knows better how it works please chime in.
