Its very unfair that others are allowed to trade during off hours and us retail investors have to wait until 930(?)

Everytime i look at a particular stock that i owned and trying to sell at a specific $, its alwys above that limit between 8 and 9 and by 930, it has dropped below and i jave to keep holding and pray i get lucky later.

Ppl are really making millions and shutting us off the opportunity to make our little 2 dollar profits.
