That is one way to trade them but I disagree it is a requirement. You can hold these for 10 minutes to 3 hours and ride the wave. That is exactly what I do. You may be influenced by Ross Cameron since he does rapid trades, but he has people jumping into stocks right behind him. You can't mirror his results and it's not the way most people are trading these stocks.
Most of my trades are stocks under $10. Wall Street firms can't effectively trade small/micro caps moving with high volatility. They need to move far more money in and out of trades just to cover their office, salaries, data fees, etc. By trading these you are not likely competing with them. That's why you can win with these. Guys at those firms are capable of seeing the opportunity but they can't make any money on them from their point of view. They are trading with tens of millions of dollars even at a very tiny firm. So if you are happy trading with an account that is under maybe $5 million then this is the sweet spot. If you need to make many millions per year then you won't find the liquidity you need with these stocks.
OTC stocks should be avoided. The deck is stacked well against you with those. Stick to exchange traded stocks.
