You who are math whizes (I'm a word person -- not numbers as much) -- you talk in percentages all the time. How in the world do you figure out the percentages so fast - 5% above this -- et cetera (I can do 10 percent -- that is simpler) on setting your limit orders? Is there an easy way to know? TOS doesn't give percentages -- Street Smart Edge -- old Schwab -- did give percentages in the order form (helped me greatly). Any tips for quickly entering orders on TOS?
