TC, the straight VTO method uses lower/upper limits of 30/50 respectively. How did you arrive at 28 for a lower limit in CSGCOS(not that it is that much different, and have you ever looked at increasing the upper limit to say 60 or 70 or waiting for a confirmation (such as decreased volume), before issuing a "sell/short"? I was using a modified VTO before coming to iHub, and I've noticed by bailing consistently at 50 you often leave a lot of money on the table, and volume dropoff is a pretty good sign that buying interest is fading. DMI might also be useful as a confirmation. Bottom line, by bailing at 50 you can miss a good portion of a sustained uptrend (may have a corollary on the downside as well).
