this is actually true and a good suggestion...
you would have to put in a high GTC order (like 30% to 40% above what it currently is) and your shares can't be borrowed by your broker.
you just need to be sure you adjust this order from time to time; wouldn't want to sell early!
GTC are also good because there have been times when a stock ran extremely high, and then crashed. by selling at a certain point in between, you still made a profit and can get back in without having taken a ridiculous loss.
ill probably place a GTC order at .25.. sounds ridiculous right now, but then again, it doesn't.
one way to practice is to set up a GTC order for 1 share, at, lets say, .002. and watch it go through. doing it is always the best way to learn.
