In the time I've traded pennies, stocks tend to trade in small steps until about 3+ cents.
My example would be people putting orders for the ask to be 0.0112, 0.0115, 0.0117 instead of 0.03, 0.031, 0.035.
It's annoying because when prices are where they are, you're making a ~0.3% in stock price. Unless you have tons of money invested here (tens of thousands) then sure you'll see a profit in the $500-$1000. But what if you made a 0.001 increase. You'd make bank! Like today! Stock goes up 0.0021 and we go up ~%22. I made 1/3 of what most people make in a year today (where I live). I think of this as value though ;) I'll probably hold until they finally get their debt completely gone. Then, we'll fly super high. Atleast a x10 multiplier in share price. I've traded those situations before and boy are they the best way to make bank!
