Use stop-loss orders: Possibly the single most important tactic for investing well in penny stocks is to use stop-loss orders. Basically, you commit early on to immediately sell your shares if the price dips to a certain point.

You may see better overall trading results by selling your losing positions very early and letting your gains run.

It can be helpful to start with paper trading, or simulated trading that allows you to practice without risking actual money. By keeping track of pretend money, and making imaginary trades, you'll learn what tactics work and what sorts of penny stocks provide you with the greatest profits.

That set amount buys more shares when the stock price goes down and fewer shares when it rises, but overall, it evens out the average price you pay. Some online brokerage firms let investors set up an automated investing schedule.
