Don't go with any percentage apecifically. Once up, whatever that is for a particular day, take profits and reevaluate. Setting limits of, oh when it is 20% I'll take profits, will get you in trouble. You'll be at 15% one day and say, well it isn't my 20%, then next day it plummets. So just take any gain asap and never look back.
