if you are trying to make some money by trading in and out of a stock using price variations / oscilations , then it is much more difficult to do it with stocks of low price levels - the reason is that percentage wise the spreads are far greater and take away most of the profits made ..........
ie. the percentage spread on trading a stock of at a price level of $0.18 compared with a stock of say $5.18 is far greater .....
