I've been following DYN to possibly add to my portfolio. On paper its a great stock because its very volatile, but watching the spread on it makes me wonder how anybody trades it! It goes from a low of .10 to .70+ every 10 seconds! The volume is large around 5 million per day. That seems like a big spread for such large volume, is there justification for this? Do people make money trading this on a short term basis? My trades are 1/2 hour to several hours and I can't justify trading it, especially with IB's backward stop algorithm.
