SG,
You put a lot of emphasis on determining support and resistance, as it shows on the chart. Once you see it approaching an S/R point, how do you determine if it respects it once it reaches it? Or, how do you determine if it blow right through it? This G/U chrt is an excellent example of it hitting support multiple times, but I don't know how you can tell that it isn't continuing down in the spots where it went below the purple line.
